How to reanimate a car battery at home?

Probably, every car enthusiast at least once came across the situation when the battery for some reason refused to work. This is a serious problem if you need to urgently go somewhere. Many will go and acquire a new battery. But, knowing how to reanimate the battery of the car at home, you can not only restore the battery, but also to extend the life of its operation for another a few years.

But for starters, let's understand actually in the structure of the Akb itself and the principle of his robots! IT'S NOT HARD!

The battery is a hermetic plastic container, inside which negative and positive lead plates are installed. In modern models, the plates can be not only from lead, but also nickel, cadmium and other alloys. The inside is also sulfuric acid - thanks to it, a galvanic pair is formed.

When the current terminals are driven by the battery, the accumulation of energy will begin. When the capacity limit is reached, the battery will turn into a voltage source in 12 V. every time the bus owner turns its car, the battery loses part of the energy. But as soon as the engine starts, the generator must fill the energy reserves. But it is only ideal. Therefore, sometimes the battery is discharged to the limit, and how to reanimate the battery, a motorist, especially a beginner, does not always know. The reasons for which the battery fails, a lot. Statistics says that a large amount of batteries fails due to sulfation and sinking of smeared.

Sulfate - one of the reasons for the exit of the battery

The battery is a source of electricity of chemical type. If the battery is charged, then sulfuric acid - in electrolyte. With a discharged battery, it is on sulfate electrodes. The operation is reversible when charging and this is a normal process. If you leave the battery for a long time discharged, then lead sulfates will be dissolved, and as a result they will begin to form on electrodes in the form of large insoluble crystals.

How to reanimate a car battery at home?

Sulfate layer - insulator. As a result, part of the battery capacity is lost, and if the battery has long been in a state of discharge, it will die. Diagnose sulfate is very simple - the battery capacity is rapidly lost, insufficient power to start the engine, the electrolyte boys and the plates overheat. There is also a higher voltage on terminals. Calcium sulfates in modern batteries Leads are doped with calcium. This allows you to reduce virtually minimizing water boiling and reduce self-discharge. However, if the battery is discharged quite strongly, the electrodes are covered with calcium sulfate. To charge this battery will not succeed. Due to the fact that the internal resistance of such a battery increases, it is believed that it needs to be charged with voltages from 15 V. This is an error. You need to know exactly how to reanimate the battery, otherwise you can kill it at all.

Well, now, let's turn to the very essence of the topic! So how to actually extend the life of our battery?

The main way that is used for batteries of a variety of modifications is charging with a small current. The battery is quickly charged and also discharged. In a short period of time, the power source ceases to take the charge. Here it is necessary to take a pause, and then repeat the cycle. It is necessary to know exactly how to reanimate the car battery - when choosing incorrect charge parameters, you can completely destroy the battery. Thus, the current of the current should be only 4-6% of the battery capacity. For example, for 60 AC batteries, the charge current is allowed not more than 3.6 A.. Often, the time of one such cycle is about 6-8 hours. Pause - from 8 to 16 hours. For recovery, 5-6 such cycles may be needed.

How to reanimate a car battery at home?

It is possible to stop the procedure if the electrolyte density is restored, and the voltage level is in the limits permissible for a specific battery.

Restoring procedures at home

This option is suitable for those who do not have time. Experienced motorists use it for a long time. If someone did not know how to reanimate the battery, then this method involves dissolving sulfates by washing with special solutions. First of all, the battery is charged to the maximum of its capabilities. Next, the electrolyte is drained, and the insides are washed with distilled water with 2-3 times. Then, a solution of ammonia and a trilon B is poured into the cavity and leave the battery for an hour. When the reaction is over, it will be visible. Gas release will stop. Then the process should be repeated if the plates were not cleaned enough. After all, the battery is washed again, the electrolyte is poured and charged by the standard way.

How to reanimate the old car battery

Manufacturers of the battery are recommended to throw out old batteries at the end of the term. Do not hurry with this - there is an opportunity to revive them. Today in many cities there are companies on the buying of old batteries - they are reanimated and then sold at an acceptable cost. If one such is one in the garage, you can try to return to him the hadacities. One should only know how to reanimate the old battery so that everything happens. After all, even the Chinese battery will cost at least 2000 rubles, and these are any, but still money and they can be saved

Getting processed

First of all, define faults. Black electrolyte is destroyed coal plates. The container fell - sulfate. There is also a closure of plates, but on how to reanimate the battery with such a problem - we will tell below. Heavy case - swollen Bock battery. Here only replacement.

How to treat closure plates

To eliminate this problem will help a special additive.

How to reanimate a car battery at home?

It is added to the electrolyte, the density of which is 1.28 g / cc, cm, and leaves there for two days. After that, the mixture is poured into the battery and the density is measured. If the indicator remains at the same level, it is charged and discharged. If heating or boiling is not observed during the process, then the current can be reduced twice. After two hours, the density of the electrolyte is measured again. If it is normal again, charging stop. We can assume that the battery is restored. If the density has grown, plotting water. When it decreased, then sulfuric acid. After that, he is charged again!

Today we will talk about ways to restore the car battery, the reasons for the exit of it and the system, as well as affect the topic of the device and the principles of operation of the AKB.

The power plant of any car, be it gasoline or diesel, starts using a special power electric motor - starter.

But that the starter starts to work, it needs to be powered by electricity. To do this, an external source of electricity is provided in the auto - rechargeable battery (battery, battery).

The main task of the battery includes short-term output of the electricity of significant power per starter to ensure the launch of the power plant.

In addition, the battery provides energy all the electrical devices of the car, until the motor starts, after which the on-board network washed from the generator.

Now the batteries are produced, which are used on cars, several types: acid, alkaline, and recently appeared gels.

Acid batteries have the greatest distribution on cars, so we will be considered.

2

The design of the battery is quite reliable, and nevertheless there are cases of damage to batteries or due to non-accurate use, or in case of incorrect maintenance.

Further use of the battery on the car during damage is impossible. But if a relatively new battery was damaged, you should not change it immediately, you can try to restore it.

To begin with, we will understand what the design of the acid battery.

If you look at it, it consists of a closed plastic housing with two derived terminals.

Structurally batteries are serviced and maintained.

At the serviced battery there are closed holes in the upper part of the battery case.

Unnwided batteries with such holes are not equipped, there is only a small hole for gases.

3

Inside, the case is divided into 6 sections called by banks. These banks are placed working elements of the battery - a set of positive and negative lead plates with an active mass applied to them.

They are arranged, that is, a positive plate, next to it is negative, then again goes positive.

Additionally, to eliminate the possible contact of these plates between them is the separator.

4

The plates are combined into blocks, each unit has an output jumper - a barlet that is connected to the bridge. With the help of Bartka, the blocks of each bank are interconnected into a common bridge with an output to the terminal.

5

The return of electricity at the battery is made due to chemical reactions, therefore the banks are filled with an electrolyte - a strictly dosed solution of acid with distilled water.

By itself, the battery does not produce electricity, it is, in fact, is simply storage of electricity.

When charging the battery incoming electrical energy from the charger or the generator is converted to the chemical. And when discharge, the opposite effect is performed.

All this is valid for this: when the energy consumer is connected to the battery, a sponge lead of negative plates with a lead plate of a positive plate and electrolyte is introduced into the reaction.

Between them occurs. The reaction, resulting in the release of electricity, which is consumed by the consumer. At the same time, a lead sulphate layer appears on negative plates.

When charging the battery, a reverse process occurs, as a result of which the layer of the sulfate appeared is dissolved in the electrolyte, and a layer of lead dioxide is formed on the positive plates.

If it is simple, then when the battery is discharged with a positive led particle plate due to chemical. Reactions are transferred to negative. And when charging the battery, these particles are returned back to positive plates.

All this is accompanied by the release or consumption of electrical energy.

Elimination of external faults

All accumulatory batteries can be divided into external and internal.

External faults are only two - the strong oxidation of the terminals, which is why there is a bad battery connection with an on-board network.

6

The second fault is a breakdown of the body or because of the external influence on it, or the crack on the housing is caused by internal faults.

7

Regarding the terminals there is nothing to say if a strong layer of oxides is seen on them, it is written.

The breakdown of the body to identify is easy - electrolyte will flow from it. The crack, if any, can be seen, but only if the battery is served.

The electrolyte merges from the battery, after which it will be possible to close the crack.

To do this, you can use the soldering iron and a piece of plastic. First, the crack itself is missing, and then for greater confidence over the prepared plastic prepared.

After that, it is necessary to check the tightness of the case, the bay of the distilled water.

Internal malfunctions

Internal faults that occur in the battery are much larger, and most of them damage the batteries harm that cannot be eliminated.

One of the most common battery malfunctions is plate sulfate.

An irrigated operation of the battery leads to the Sulfatition of the battery - long storage of the battery in the discharged state, frequent deep discharges, constant shortage of the battery, so it is important to pick up the battery on the car brand.

Sulfation itself is an education on the surface of the plate sulfate plates, due to which the electrolyte cannot penetrate the active mass, so part of this mass can no longer be react.

8

Resistance inside the battery increases, so the container falls, as a result, the battery cannot take a completely charge and quickly discharged.

In the early stages, the sulfate of the plates can be eliminated, but if it is deep - the battery is not repairable. There are such malfunctions as shrinking of the active mass from the plates, with a possible subsequent circuit.

Usually, when unscrewed squeezes helps washing with distilled water by batteries.

Perhaps the blink of the battery due to the freezing of the electrolyte. It happens if the discharged battery was at a strong frost.

Recovery car battery after freezing is not subject to.

Ways to eliminate sulfation

The methods of eliminating the sulfate of the plates apply several.

The first method.

The first, the most common method is to conduct a training cycle (CTC). The use of this method will allow to eliminate sulfate in the early stages and restore the capacity of the battery.

The essence of this method is reduced to the Cycle charge-discharge. For CTC, you need the presence of a charger, aareometer, voltmeter and source of electricity consumption.

First, a full charge of the battery is performed. The charging of the battery is performed by a current equal to 10% of the nominal capacity, that is, with the capacity of the battery in 60 Ah, the current should be 6 A. after charging, the density is checked.

9

This indicator has a fully charged battery should be 1.27. If this value is below, the density will be made to the desired value, followed by a battery processing for half an hour so that the electrolyte moves.

ten

After charging, a controlling discharge is made. To do this, the terminals are connected by the source of energy consumption. In this case, energy consumption by a connected consumer should not exceed 10% of the tank.

It is best to use a car lighting lamp as a consumer with a certain power.

eleven

Calculate the power that can be needed by multiplying current and voltage. The strength of the current is taken from the calculation based on the battery capacity.

That is, when calculating the power that is needed for the discharge of the battery by 60 Ah, the current is taken 6a, this value is multiplied by 12V. We obtain the power value of 72 W, approximately such power and need a lamp.

Next, the battery is discharged with a lamp, while the voltage is periodically measured.

The discharge battery needs to achieve a reduction in voltage at terminals to 10.2 V. This voltage value will indicate the full discharge of the battery.

At the same time, the time for which the battery discharge occurred. The new battery has a given value to be about 10 hours. The smaller the discharge time, the greater the battery lost its container.

For a long time, the discharged battery can not be left, it immediately needs to be put on charging until the charge is completely recovered.

When performing this operation, the battery capacity will be restored, and due to the reduction of sulfate, it is reduced to internal resistance.

Next method.

The second method of removing sulfation is the use of reversing currents when charging the battery.

The disadvantage of the reversing current method is the need for special equipment - reversing current generator.

The essence of this method is reduced to the long-term charge of the battery with small currents.

So, with a minor sulfate, the battery is charged with a slight current - 0.5-2 A. And the charging is carried out for a long period, sometimes can reach 50 hours.

The end of the desulfation process is the invariance of voltage on terminals, as well as the unnecessary electrolyte density for 2 or more hours.

12

The third method used to restore the battery.

Is washing the battery with subsequent charging. But this method is long and delaying its execution can up to a month.

The electrolyte is drained from the battery, and distillates poured into its place. After that, the battery is put on charging at a voltage of 14 V.

thirteen

After the start of the discharge of distillate - the voltage is somewhat reduced. The main goal is to maintain boiling into the battery, but non-intensive.

Over time, the distillate density will increase due to dissolving lead sulfate in water. After that, the water merges, and the new and the battery is poured again for charging, under a small tension.

It is necessary to ensure that bubbles appear in distillate, but it did not communicate before boiling.

On charging, the battery will need to be kept until the density has changed for several days.

Chemical method.

There is a quick way to remove sulfation - chemical. It is reduced to washing the battery with a solution of ammonia and a trilder b

14

Before washing with a solution, the battery is charging, the electrolyte merges with it and is washed with distillate.

Then the aqueous solution is poured into the jars, in which 2% of the volume of the water of the trilone b and 5% -amyamia is added.

15

This solution will react with sulfate solution, this reaction is accompanied by a boiling solution and splashes.

As soon as the boiling is stopped - the solution can be merged, the banks are washed with water, and then the electrolyte is poured and the battery is charging.

Battery fault prevention

All malfunctions with the battery do not arise by themselves, they happen due to negligent operation and ignoring periodic maintenance.

The battery itself requires not much attention. It is enough to recharge its charger in half a year.

Before charging, if the battery is served, you need to trace the level of electrolyte and to restore it when necessary.

Also follow after charging, check the electrolyte density in each bank.

Differences on density testimony between banks should not be, or the difference between them should be minimal.

Before installing a new battery on a car, it will be necessary to check the voltage issued by the generator to eliminate the reload.

And installing a new battery on the car you need to fasten it well to prevent possible damage to the case. The source is www.avto-pulss.ru

Greetings to you friends. Today I will tell you about the most effective method for restoring the container in lead acid batteries.

In the period of even the right to operate, the battery loses its container every day. And at one fine moment of his charge lacks to start the car engine. This example is exacerbated with the arrival of cold weather.

The most effective way to restore the battery

Naturally, the car enthusiast puts the battery for charging and after some time sees that the battery does not charge, and the voltage during charging stands as normal - 14.4-14.7 V or higher (12.6 without a charger).

The most effective way to restore the battery

Then if there is a loading plug, the check is made to it and it turns out that under the load, the voltage is very sensitive. Everything indicates the battery loss. The reason for this is the sulfate of the plates.

The most effective way to restore the battery

Usually, with proper operation, this occurs in about 5 years. This is a very good indicator. And here there is a way out - buy a new battery. But, if you want to save money (as the batteries are not cheap now, and extend the battery life for another couple of years, then it is necessary to carry out its service. And not a simple, but a special that can reanimate the battery.

What batteries can be restored?

This method is suitable for batteries, which during the period of operation have not been susceptible to serious current or mechanical damage. And they were unusable as a result of temporary, natural sulfation.

This method is not suitable for rechargeable batteries in which there is an inner swap plate, there is an internal closure of cans, there is a swift or other mechanical damage.

The method is excellent for desulfation of plates and is called the people by the method of "revroves" of the battery.

I divide the recovery battery into three stages.

Battery recovery process

Stage First: Preparation

The first thing is not necessary, but you need to do this to clean the surface of the battery from any contamination. Rinse with detergent all surface.

Further, to be visually verified in the absence of damage on the housing, in the absence of fuses and convexities on the sides.

Second, open all jacks of cans and make sure that the electrolyte is available. If it is not in one of the cans, then you need to make sure there are no cracks on the case.

Then, with the help of a flashlight, inspect the plates inside - ships should not be. Here just for one one can clearly see sulfate - white bloom on the plates.

The most effective way to restore the battery

If everything is in order - add distilled water to each jar to the level. It will not be superfluous to measure the density of the electrolyte of each compartment.

Stage Second: Classic Recovery Method

Before switching to the storage of the battery, you must test the usual restoration method that has already become classic.

Step one:

We charge the battery to a complete charge of 14.4 V.

The most effective way to restore the batteryStep two:

The halogen light bulb or another load is discharged by the battery to 10.6 V (the voltage is measured under the same load).

The most effective way to restore the battery

We repeat the cycle of these two steps 3 times and charge the battery for complete. Check the capacity of the load fork or starter in the operation of the machine. If the battery recovered - well - continue operation. If not, or not enough, then proceed to the third stage.

Stage Three: Rechacter Revolutionary Battery

This battery recovery method is the most effective of all existing ones. And reanimits the battery in almost 90% of cases.

Step one:

We hang on the battery load in the form of a halogen lamp, and discharge the battery at zero. The lamp will go through after a day (it all depends on the initial capacity of the battery). We leave the battery with the connected lamp for another 2-3 days to finally discharge the remnants.

Step two:

Charging the battery reverse current. Connect the charger on the contrary: plus to minus, and minus to the plus. In order not to spoil your charger (or so that the protection against short circuit does not work), the battery consistently connect the same halogen lamp. And charge the battery in reverse polarity. After the voltage rose to Volt 5-6, the chain lamp can be excluded. Charge current It is advisable to put 5 percent of the battery capacity. That is, if the capacity of 60 amps-hours, then the charge current in the opposite direction is 3 amps. At this time, all the banks with electrolyte begin to be actively brown and hiss it is normal, since there is a reverse process.

The most effective way to restore the battery

I charge about a day, until the voltage appears 12-14 V. In the end, you turned out a fully charged battery with which at the output of the plus - minus, and on the minus - plus.

The most effective way to restore the batteryStep Three:

Again, completely discharge the battery with a halogen lamp for a couple of days. Then we produce the correct charge plus to the plus, minus to minus. We charge to full up to 14.4 V.

On this all actions are completed.

Recovery Battery Recovery Result

Typically, the result helps to increase the battery capacity to 70-100% of the factory, of course there are exceptions.

Specifically, in my case, it was possible to raise the container by 95% - which is an excellent result. The plates disappeared white sulfate flying, and they purchased a black color like a new battery. The electrolyte has become more transparent and clean.

Battery recovery video

I recommend you to watch the video where the battery is completely restored, which is about 10 years old.

At first, there is a "routing" with a change in the polarity of food, and almost at the very end already given a full cycle of ransom.

Purpose of the AKB is to start the engine starter and maintain the power of consumers in the electrical on-board network, together with the generator. If the car battery does not perform functions, the restoration of working capacity or replacement is required. Knowing the principle of operation of the battery, the design, you can try to return the battery with your own hands.

How to restore AKB

Types of malfunctions of AKB

Not always the first sign of the malfunction of the battery is the loss of tension. It can be detected, the body of the device has given a crack, or the terminals are covered with a salt tap. Restoring the housing integrity and cleaning the battery terminals with their own hands belong to the elimination of external breakdowns.

Internal faults of a car vehicle require recovery:

  • Capacities deeply discharged battery;
  • Chulfate sediment sediment in cathodes;
  • the closure between the variant plates leading to the discharge of the electrolyte and warming the cans;
  • Sowing of the active mass with plates leading to a closure.

It is impossible to restore the automotive battery with their own hands if the housing and plates are deformed due to deep polling. If the lead plates are destroyed, the case of the housing, the battery is disposed of.

Akb on disposal

Restoring the car battery do it yourself

If there is an almost new car battery, the owners are trying to perform recovery with their own hands, or because of a faulty generator. This is possible, but more problems with the repair of a non-servant battery.

Regardless, whatever the operation is carried out, you need to remember protection. The electrolyte is a concentrated solution of sulfuric acid, well reacts with the skin, charring the skin. When cleaning the terminals, it is necessary to use rubber gloves, all levels of level and density of electrolyte in open banks lead in protective glasses.

Is there suspicions of microcracks in the case? Moisten the surface and put a litmus paper. If it blooms - look for leakage. But dust during cleaning terminals is also soluble and gives an acidic reaction. Consider it.

Any hull wash, electrolyte drain can be carried out in enameled or plastic dishes. Remember, when diluted with water, the temperature of the solution rises. Neutralize spilled electrolyte can be drinking soda.

We offer to see ways to restore the car battery do it yourself on video.

Restoration of the car battery after deep discharge

The battery does not produce electrical energy, and retains it converted to chemical. Voltage is the potential difference between the two terminals of the element. It must be equal to 2.1 V with full charge. During charging, positive particles are collected on the anode, absorbing electrical energy. Distinguishing, ions from the anode go to the cathode, give energy in the form of a pulse to the network of the consumer.

The conductor serves an electrolyte - a solution of sulfuric acid of standard density. During the discharge period, small PBSO4 crystals appear on the surface of the plates. But deep discharge leads to the formation of large insoluble crystals. This means the electrolyte is impoverished, becomes weaker and is not able to create the desired energy capacity. Education on the plates of insoluble sediment makes it difficult to pass the current, resistance increases. Battery sat down. The recovery of the battery charge depends on the destruction of zinc sulfate sediment.

terminal

Another reason for the loss of the capacity may be short circuit in one or several elements. Negative and positive plates are separated by separators. But the blow, permanent shaking, a bad fastening of the housing in the nest can cause displacement of the plates, their contact. The sign will be the heating of the case, the loss of general voltage by 2.1 V (non-working bank). Restoration of the capacity of the AKB with CW requires replacing the cans or exposure to a pulsed current in 100 A.

Recovery of the capacity of the automotive battery

Even if there was no deep discharge, but the battery operates in a dilapidated state, the plate sulfate will occur inevitably. The thicker precipitate, the lower the electrolyte concentration, the battery capacity.

The capacitance schemes of the capacity of the battery are to restore the density of the electrolyte and the ability of the battery to receive a charge.

  1. Disassembly of plates and their mechanical cleaning is used if another method is only disposal. The holes are cut into the housing cover, remove plates. Distilled water was washed cavities and plates. The tightness of the design is restored, the electrolyte is poured, charging is performed. But since the plates are fragile, the restoration of the acb in this way - the job is jewelry.
  2. Chemical dissolution of crystals can save the fully sex battery. The active substance is a trildon solution B. should be discharged by the battery, drain the electrolyte, rinse the insides with distilled water. In pure banks, pour a 2% trilon solution b and 5% ammonia in a calculation for the entire volume. Within an hour, boiling and gas formation will be observed. Perhaps the solution will have to fill it repeatedly if the reaction of the dissolution of the sediment continues. After draining the solution, rinse with distilled water and pour fresh electrolyte. Carry charging.

Electrolyte density

Charger for restoring car batteries

  • The dissolution of crystals at an early stage by the method of a control cycle. You will need, ammeter and voltmeter, consumer of energy. The principle of recovery of the car battery density is to use multiple charging cycles with full battery discharge. The operation is performed with your own hands but requires a lot of time.

Charging is conducted with a current of 0.1 from the initial battery capacity. The density of the electrolyte is measured in each bank, is communicated to the norm, for mixing the charging is still half an hour. After the incandescent lamp is connected to 70 V as the current consumer. At a voltage of 10.2, the battery is considered discharged. The discharge time determines the remaining battery capacity. The new battery is discharged 10 hours.

The cycle is repeated several times, sulphate crystals dissolve, the resistance drops, the battery discharge time increases. The process of cleaning the plates from the sediment must be continuous. This is the best way to restore the old or maintenanceable car battery.

Сульфатация пластин

  • You can dissolve sulfate stone without chemistry, using only distilled water. Akb's flooded water is charged, under the voltage of 14 V. Weak boiling in banks is maintained by voltage regulation. In the process, the density of the fluid varies - the dissolution of the precipitate is underway. Water changes several times, the process may take a month. After cleaning the plates with dissolution, the cavity is washed and poured with an electrolyte of the desired density.
  • When no methods help the restoration of the car battery, use the surveillance. The method will help if the battery is high-quality, the electrolyte is transparent, just visible on the plates. Sulfates are deposited on the anodes. If the plate is minus, the precipitate will collapse. With a fully discharged battery, we connect to the reverse current by force of 6 A, we decrease to 2a, add resistance to reduce the acb bars warming up. Recovery is accompanied by boiling cans. After it is necessary to reassure the device. Capacity will return or the battery will finally collapse.
  • There is a special charger for automotive batteries with a function of pulse mode and desulfation. Capacity recovery scheme:

Charging on a small current 10 minutes;

Discharge under load 1 minute.

The cost device is commensurate with the price of a good battery. It is more often used to restore and charge automotive batteries. An ordinary charger.

Восстановление банки

If the bank closed in the battery

The first sign of the failure of banks will be the voltage drop to 10.5 V. The second is the boiling of the battery and the sulfate of the plates. Detect a faulty element by electrolyte density.

You can free up the jar from the electrolyte, rinse and remove the plate from it. After inspecting and eliminating damage, the contour is restored, searched. Sometimes the bank is replaced by a similar, from the non-working battery. The element is placed in place, the connection is restored from the car battery terminal.

The closed battery bank is the cause of its disposal. Sometimes a risky effect of exposure to the problem area by a pulse with a current of 100 A for 1-2 seconds is used. The location of the plates must melt - point contact and great resistance. However, it is worth risking if the battery is preparing to write off.

Video

We offer to watch a lesson how to restore a very old battery.

Many cars have many, but do not everyone know how to restore the battery after breakdown. The car battery feeds the vehicle with energy, but after several years he can fail. Under normal conditions, the device is enough for five years. Как восстановить аккумулятор автомобиля в домашних условияхIf the battery has become given signs of breakage, which is not necessary to run to the store and get a new one. There are several ways to reanimate acb.

Signs of wear

To understand that the battery will soon fail, it is necessary to possess some information - learn the main signs. Without the necessary knowledge, the restoration of car batteries will be difficult. It will take carefully to follow your car. Only in this case it will be possible to take the necessary measures to repair, in particular the rechargeable battery.

There are several basic signs:

Как восстановить аккумулятор автомобиля в домашних условиях

  1. If the battery quickly loses its charge, then you need to worry about. This is the first sign of a decrease in the quality of the electrolyte poured inside.
  2. Another correct feature of the battery malfunction is a very fast charge through a special device. The reason for this will be sulfate, which has already begun.
  3. Electrolyte darkened. If the substance has become dark, then it is necessary to immediately begin to restore the battery, because it is one of the main signs that coal plates begin to crumble and collapse.
  4. If separate battery sections are heated or the electrolyte boils, this is due to the closure of the plates or damage them. The main reason for this malfunction becomes what the car has a long time without action on strong cold. The plates can climb, and the body of the device will cover ice. As a result, a closure will appear, which, in turn, will lead to very rapid boil when charging the electrolyte. This malfunction is already very serious, and in most cases the device will not be resurrected.

The battery can be restored almost in all cases, if it is not fully running. The operation can be quite expensive, but the money will go much less than when purchasing a new unit.

It is necessary to carefully refer to the operation of the battery and immediately notice various problems. From this will depend on the life expectancy of the AKB. Before you begin to directly restore the car, you need to find out which parts of the battery are subject to resuscitation.

Electrolyte density

Как восстановить аккумулятор автомобиля в домашних условияхThe electrolyte is poured inside the rechargeable battery . This substance is usually a kind of acid and water cocktail. If the battery nickel-cadmium or nickel-iron, then in this case the alkaline electrolyte is poured inside.

We recommend: how many kg of lead is contained in a 55 ampere battery

Before you start repairing the battery, you need to know the electrolyte density. To do this, use the device called an areaometer.

It is not necessary to spend a lot of money on his purchase, it is selling absolutely in any store with auto parts. And you can also use a voltmeter to measure the density of the acidic solution.

Turns off the equipment to the car terminals.

In the disconnected state, the numbers must be equal to about 11.9-12.5 V. After that, we turn on the car, gain 2500 revolutions and measure it again. If the voltage is equal to 13.9-14.4 volts, then the density within the normal range. In this case, the old battery must only be recharged. But, if the indicators are too small, you will need to restore.

Several ways to resuscitate:

Как восстановить аккумулятор автомобиля в домашних условиях

  1. Using the battery charger and the charge to 100%. You can't lose charge.
  2. Full replacement of the solution from the Akb to the new one.
  3. Use of an elevated density electrolyte.
  4. Adding only sulfuric acid.
  5. Adding only water.

Before restoring the acid solution, it is worth trying to simply recharge the equipment. Sometimes it happens that after such an easy procedure, all problems disappear.

If after charging, problems with electrolyte appear, then it is necessary to change the density of the solution in the battery.

Water in no way pour in sulfuric acid . It is very important. Otherwise, you can get very serious damage to the skin in the form of burns. Water will boil and will splash in different directions. Restoring car battery needs to be made carefully.

Destruction and closure of plates

If the plate collapsed on the battery or only the plates begin to collapse, then it is necessary to immediately take measures to recover. If the battery collapsed significantly, then it will not be possible to restore it.

Как восстановить аккумулятор автомобиля в домашних условиях

That is why before resuscitation, you need to make sure that this is not a useless occupation. The process of destruction can be stopped only if it just started. A pretty embossed device to reanimate makes no sense.

If there were signs of destruction, you can immediately wash the jars:

  1. First you need to fully discharge the device by connecting any load to the battery. For this purpose, a conventional light bulb is usually used.
  2. All damaged mortar is removed from the cans. For this use rubber pear. The solution is placed in glass dishes, which was previously prepared.
  3. Banks are wedged with distilled water until full purity. Akb When cleaning, you must constantly turn over and shake.
  4. If there is a lot of dirt inside, and the crumb of coal is still limp, then the process is already irreversible, because it came far away. In such a variant, the battery is no longer subject to restoration.
  5. When I achieved complete cleanliness, a new solution should be placed in the bank. Before this necessarily checked the density of the substance.
  6. The battery is set to recharging so that the previous tension returned to the desired level.

When the cleaning operation is completed, and the device is fully charged, you need to check the electrolyte again and its density. If necessary, the indicators will have to lead to normal.

Diagnosis of sulfation

Как восстановить аккумулятор автомобиля в домашних условиях

Sulfation is one of the most common problems associated with the battery. If normal operating conditions occur, during the discharge-charging in the battery there are certain processes. But when the car starts infrequently, the processes will be disturbed.

Sulfate crystals may appear on the plates. They are difficult to remove and they can lead to such consequences:

  1. Battery capacity decreases.
  2. Internal resistance increases.
  3. The volume of the plates increases.

In most cases, sulfate begins to manifest itself if the car stands for a long time without use, it is overheated or critical current conditions are served. It can be understood that sulfate began, seeing the drop in charge.

To determine this indicator, you must use the tester. If a defect is found, you need to think about the ways to restore the battery in the next time. You need to act quickly until the device is still able to restore.

For recovery it is necessary to use a special additive to the electrolyte. A desulfator is usually used, which dissolves the formed crystals. These were the main faults.

Having studied them, you can learn how to reanimate the car battery at home.

Chemical methods of recovery

The chemical type of home battery recovery is quite effective. Professionals allocate three basic methods. Recovery options:

  1. A simple variant of the rechargeable battery with your own hands: Banks need to be cleaned and pour them with distilled water. The battery is charged with a weak current of 0.01 from the tank. Sulphate lead will slowly disappear from the plates, and a new electrolyte is formed. This process must be made within a few hours, and after making a small respite. And after starting charging again. It will takes the use of several cycles. As a result, sulfation drops sharply, and the electrolyte that has been formed again in banks will affect performance. Как восстановить аккумулятор автомобиля в домашних условиях
  2. The battery needs to be charged 100%, after draining the acid solution. After that, the cans are very well washed with distilled water. They are placed a solution of drinking soda. The concentration must be 25 g per 1 liter. The substance will need to be left in the battery for about 2 or 3 hours. After that, it is necessary to replace this substance with a solid salt. The concentration should be the same. The device needs to be charged for one hour. After this process, the salt concentration increases to 4%. Battery charge completely. After this process, the banks will need to rinse well with distilled water. The battery is filled with electrolyte and charging.
  3. The battery needs to be fully charged, after draining the electrolyte and rinse the cans with distilled water. The trilon b and ammonia is poured inside. It turns out a good reducing agent. Typically, such substances can be obtained in various chemical laboratories. The substance is stored only in the dark and carry out the room. The bank in no case can be left open. Desulfation will occur within one hour, after which the chances of reviving the battery will sharply rise. During operation, the substance will begin to highlight the gas, and small splashes will be noticed on the surface. When splashing ends - the process is completed. After processing, flush the battery with distilled water several times. A new electrolyte is poured and the battery is fully charged.

Not every degree of sulfate can be restored with your own hands. That is why it is desirable to notice this process as soon as possible by car.

Account Care Tips

So that the battery worked without interruption, you need to constantly and competently and perform Uncomplicated tips:

  1. Regularly will have to be observed for the electrolyte and its density. The main cause of boiling is the reload or overheating of the device. The faster the problem is discovered, the greater the chance of recovery.
  2. If in the winter period the car is not used, the battery needs to be removed and placed in a well-heated room. If the battery is frozen, it will not be possible to restore.
  3. Rated current - 0.1 from the capacity of the entire battery. If this threshold rises, the device will not restore.

Recommended: Search and selection of the battery on the brand and car model

These are very simple battery maintenance tips in proper state. Do not neglect them. Only in this case the battery will work for many years without interruptions. Restoring the car battery is not a difficult thing, but it will be necessary to make efforts and explore the main fault. After examining all the tips, you can understand how to restore the car battery on your own.

How to restore the efficiency of a car battery?

The performance of the car strongly depends on the technical condition of the battery. It is worth it to discharge or fail, and it becomes very difficult to operate the car.

Constantly push either to take a vehicle in tow - no way out. Because the replacement of the power source is the pleasure of the cheap, the natural question arises, how to restore the car battery in a regular garage.

Often extending the service life is quite real.

About the design of acid battery

On vehicles used 3 varieties of batteries - gel, alkaline and lead-acid.

The first are considered relatively new, they are infrequently applied and until the sufficient resource has been accumulated to talk about recovery. Alkaline batteries are found on commercial transport, electrical loaders and carries.

The overwhelming majority of passenger cars are equipped with acid acb, so their resuscitation is considered to be considered more.

The lead-acid battery is a hermetic plastic case, which elements are placed:

  • Positive electrodes (anodes) in the form of lead plates with an active filler collected in blocks (on jargon - banks);
  • Negative electrodes (cathodes) of identical design;
  • separators - insulating partitions from polymeric materials or fiberglass;
  • Connecting tires ending with two terminals for connecting the battery to the automotive power grid;
  • The electrolyte is a solution of sulfuric acid.

Negative and positive electrodes are established alternately, separators are placed between them to avoid closure. In the process of charging the battery, a chemical reaction occurs, why lead dioxide is precipitated on the surface of the anodes - energy is accumulated.

After connecting consumers, the dioxide reacts with the lead cathode lead, forming a lead sulfate layer on negative electrodes - energy is released. The gas released as a result of the reaction outward through the valve and the vent hole.

Common battery malfunctions

Restoration of the car battery is possible not always and depends on the type of malfunction. Also plays a role type of battery:

  • The serviced battery is equipped with plugs installed on top of each bank;
  • The main power source is characterized by a solid plastic housing - a monoblock without traffic jams.

If there are unscrewed covers, you can check and adjust the electrolyte density or drain the liquid to repair. The hermetic monoblock is reanimated by one way - by charging according to a specific algorithm, but the positive result is not guaranteed.

Battery malfunctions are conditionally divided into 2 groups - external and internal. Every variety should be disassembled separately.

Elimination of external defects

During the operation of batteries, motorists have to deal with two outer malfunctions: oxidation of lead terminals and cracks in the case. The latter arise for such reasons:

  • The housing burst as a result of mechanical damage (for example, the drop in the battery);
  • bloating of the discharged acb located on a strong frost;
  • Plastic became fragile from old age.

The oxidation of the terminals prevents a reliable contact of the source with an on-board network and often serves as a starter reason. The defect is "treated" with a simple stripping using large sandpaper, in the running cases - a small file. Similarly, the layer of oxide is removed from the contacts placed on the terminals and the bolted bolted.

Как восстановить аккумулятор автомобиля в домашних условиях

  1. Drain the electrolytic liquid from all cans and rinse the housing from the inside with distilled water so that the hot tool is not in contact with the acid.
  2. Dry the body from the crack side, then carefully read it along the entire length.
  3. Cut the patch from plastics and breed it over the crack, closeing the seams without skipping.
  4. Another option is to use a glue gun. The defect needs to be slightly expanded, filled with a polymer composition, and then apply a latch.

After completion, check the battery for tightness, the bay to the top distilled water. In the absence of leaks, fill the battery with electrolyte and try to charge. If the blocks of the plates are not damaged, the battery "takes" the charge and continues to serve as a car.

Note. If the housing has cracked from bloating or old age, it is unlikely to revive the battery by soldering the defect. The accurate result will only show charging performed after seeling the crack.

Internal malfunctions

Most of the internal faults unambiguously leads the battery in disrepair if the problem is too late. In the early stages, resuscitation is quite possible. The list of common problems looks like this:

  • Sulfate electrodes - deposition on the plates of a thick layer of a lead sulfate, which does not allow the electrolytic fluid to be properly in contact with the active filler;
  • Swimming filler with lead grids;
  • Closing electrodes and blocks with each other.

Reference. Short closure plates - a consequence of a large amount of active filler with grilles. The defect is critical - the battery is not subject to restoration.

Как восстановить аккумулятор автомобиля в домашних условиях

  • Multiple complete discharge of an acid-lead battery "in zero";
  • Operation of the power supply with a low level of charging due to the problems of the generator or the electrical part of the car;
  • Long storage in the discharged state.

If the problem is detected at the last stage - deep sulfate, total shrinkage - to reanimate the car battery will not succeed. The irreparable defect is diagnosed simply - the battery absolutely does not perceive the charging, the electrolyte constantly boils. In other cases, try to implement the ACB restoration methods described below.

How to get rid of sulfate?

The first way to eliminate the malfunction is suitable only for serviced batteries. For implementation, the charger will need, the device - the electrolyte density meter (range), the multimeter and the light bulb - the consumer on 12 V.

Important! The lamp power is taken by this calculation: the battery capacity (for example, 45 Ah) is multiplied by the coefficient 0.1 and the voltage value (12 volts). In this case, the power was 45 x 0.1 x 12 = 54 W.

Restoration of the faulty battery is carried out in the following order:

  1. Fully charge the current power battery equal to 10% of the power supply capacity.
  2. Check the amount of density in all banks by the area, it should be 1.27 units. If the density "displaces" to the specified digit, add the electrolyte and charge the battery for 30 minutes.
  3. Connect the lamp to the terminals and discharge the battery, periodically measuring the voltage. Do not forget to damage the start time of discharge.
  4. When the voltage falls to 10.2 volts (full discharge), turn off the light bulb. If the process took more than 8 hours, the battery is in an acceptable state (the discharge rate of the new battery is approximately 10 hours).
  5. Upon completion, charge the battery to 100% and put it on the car. Do not hold the power source fully discharged.

Как восстановить аккумулятор автомобиля в домашних условиях

  1. Layout the charger capable of producing small currents - from 0.5 to 2 A with a periodic shutdown function.
  2. Charge the battery at least 2 days, periodically measuring the voltage.
  3. Turn off the charger and check the voltage within 2 hours. If it does not fall, try to put the battery on the car, otherwise charge further.

To achieve a positive result, the charging duration can be 50 hours or more. It is preferable to use a charger in which the desulfation function is provided - it will supply the current of 2 and after certain intervals.

Method of chemical washing

This procedure is used to eliminate sulfate and rapid recovery of the battery serviced at home. It will take 2 reagents available on sale, "Trilon B" and a solution of ammonia. The procedure for such:

  1. Try to fully charge the battery, then drain the entire electrolyte.
  2. Rinse the battery with distilled water.
  3. Prepare the solution by adding 5% ammonia to distillate and 2% "trillion b" (from water volume).
  4. Carefully pour the solution into banks - a rapid reaction will begin, accompanied by boiling and spraying.
  5. When the fluid stops boiled, drain it and re-rinse the battery.

Как восстановить аккумулятор автомобиля в домашних условиях

The last method of removing lead sulfate is to replace the electrolytic liquid with distilled water and long-term charging with a voltage of 14 volts. At the first stage, the battery is brought to a boil, then the voltage decreases.

The goal is slow dissolution of sulfate with water. At the second stage, the distillate changes, and the voltage and the charging current is minimized. The operation is considered successful if the density of the solution does not fall within 2-3 days.

By duration, the procedure may take 3-4 weeks.

Battery recovery

Purpose of the AKB is to start the engine starter and maintain the power of consumers in the electrical on-board network, together with the generator. If the car battery does not perform functions, the restoration of working capacity or replacement is required. Knowing the principle of operation of the battery, the design, you can try to return the battery with your own hands.

Как восстановить аккумулятор автомобиля в домашних условиях

Types of malfunctions of AKB

Not always the first sign of the malfunction of the battery is the loss of tension. It can be detected, the body of the device has given a crack, or the terminals are covered with a salt tap. Restoring the housing integrity and cleaning the battery terminals with their own hands belong to the elimination of external breakdowns.

Internal faults of a car vehicle require recovery:

  • Capacities deeply discharged battery;
  • Chulfate sediment sediment in cathodes;
  • the closure between the variant plates leading to the discharge of the electrolyte and warming the cans;
  • Sowing of the active mass with plates leading to a closure.

It is impossible to restore the automotive battery with their own hands if the housing and plates are deformed due to deep polling. If the lead plates are destroyed, the case of the housing, the battery is disposed of.

Restoring the car battery do it yourself

If there is an almost new car battery, the owners are trying to perform recovery with their own hands, or because of a faulty generator. This is possible, but more problems with the repair of a non-servant battery.

Regardless, whatever the operation is carried out, you need to remember protection. The electrolyte is a concentrated solution of sulfuric acid, well reacts with the skin, charring the skin. When cleaning the terminals, it is necessary to use rubber gloves, all levels of level and density of electrolyte in open banks lead in protective glasses.

Is there suspicions of microcracks in the case? Moisten the surface and put a litmus paper. If it blooms - look for leakage. But dust during cleaning terminals is also soluble and gives an acidic reaction. Consider it.

Any hull wash, electrolyte drain can be carried out in enameled or plastic dishes. Remember, when diluted with water, the temperature of the solution rises. Neutralize spilled electrolyte can be drinking soda.

Restoration of the car battery after deep discharge

The battery does not produce electrical energy, and retains it converted to chemical. Voltage is the potential difference between the two terminals of the element.

It must be equal to 2.1 V with full charge. During charging, positive particles are collected on the anode, absorbing electrical energy.

Distinguishing, ions from the anode go to the cathode, give energy in the form of a pulse to the network of the consumer.

The conductor serves an electrolyte - a solution of sulfuric acid of standard density. During the discharge period, small PBSO4 crystals appear on the surface of the plates. But deep discharge leads to the formation of large insoluble crystals.

This means the electrolyte is impoverished, becomes weaker and is not able to create the desired energy capacity. Education on the plates of insoluble sediment makes it difficult to pass the current, resistance increases. Battery sat down.

The recovery of the battery charge depends on the destruction of zinc sulfate sediment.

Как восстановить аккумулятор автомобиля в домашних условиях

Another reason for the loss of the capacity may be short circuit in one or several elements. Negative and positive plates are separated by separators.

But the blow, permanent shaking, a bad fastening of the housing in the nest can cause displacement of the plates, their contact. The sign will be the heating of the case, the loss of general voltage by 2.1 V (non-working bank).

Restoration of the capacity of the AKB with CW requires replacing the cans or exposure to a pulsed current in 100 A.

Recovery of the capacity of the automotive battery

Even if there was no deep discharge, but the battery operates in a dilapidated state, the plate sulfate will occur inevitably. The thicker precipitate, the lower the electrolyte concentration, the battery capacity.

The capacitance schemes of the capacity of the battery are to restore the density of the electrolyte and the ability of the battery to receive a charge.

  1. Disassembly of plates and their mechanical cleaning is used if another method is only disposal. The holes are cut into the housing cover, remove plates. Distilled water was washed cavities and plates. The tightness of the design is restored, the electrolyte is poured, charging is performed. But since the plates are fragile, the restoration of the acb in this way - the job is jewelry.
  2. Chemical dissolution of crystals can save the fully sex battery. The active substance is a trildon solution B. should be discharged by the battery, drain the electrolyte, rinse the insides with distilled water. In pure banks, pour a 2% trilon solution b and 5% ammonia in a calculation for the entire volume. Within an hour, boiling and gas formation will be observed. Perhaps the solution will have to fill it repeatedly if the reaction of the dissolution of the sediment continues. After draining the solution, rinse with distilled water and pour fresh electrolyte. Carry charging.

Charger for restoring car batteries

  • The dissolution of crystals at an early stage by the method of a control cycle. You will need, ammeter and voltmeter, consumer of energy. The principle of recovery of the car battery density is to use multiple charging cycles with full battery discharge. The operation is performed with your own hands but requires a lot of time.

Charging is conducted with a current of 0.1 from the initial battery capacity. The density of the electrolyte is measured in each bank, is communicated to the norm, for mixing the charging is still half an hour. After the incandescent lamp is connected to 70 V as the current consumer. At a voltage of 10.2, the battery is considered discharged. The discharge time determines the remaining battery capacity.

The new battery is discharged 10 hours.

The cycle is repeated several times, sulphate crystals dissolve, the resistance drops, the battery discharge time increases. The process of cleaning the plates from the sediment must be continuous. This is the best way to restore the old or maintenanceable car battery.

Как восстановить аккумулятор автомобиля в домашних условиях

  • You can dissolve sulfate stone without chemistry, using only distilled water. Akb's flooded water is charged, under the voltage of 14 V. Weak boiling in banks is maintained by voltage regulation. In the process, the density of the fluid varies - the dissolution of the precipitate is underway. Water changes several times, the process may take a month. After cleaning the plates with dissolution, the cavity is washed and poured with an electrolyte of the desired density.
  • When no methods help the restoration of the car battery, use the surveillance. The method will help if the battery is high-quality, the electrolyte is transparent, just visible on the plates. Sulfates are deposited on the anodes. If the plate is minus, the precipitate will collapse. With a fully discharged battery, we connect to the reverse current by force of 6 A, we decrease to 2a, add resistance to reduce the acb bars warming up. Recovery is accompanied by boiling cans. After it is necessary to reassure the device. Capacity will return or the battery will finally collapse.
  • There is a special charger for automotive batteries with a function of pulse mode and desulfation. Capacity recovery scheme:
  • Charging on a small current 10 minutes;
  • Discharge under load 1 minute.

The cost device is commensurate with the price of a good battery. It is more often used to restore and charge automotive batteries. An ordinary charger.

Как восстановить аккумулятор автомобиля в домашних условиях

If the bank closed in the battery

The first sign of the failure of banks will be the voltage drop to 10.5 V. The second is the boiling of the battery and the sulfate of the plates. Detect a faulty element by electrolyte density.

You can free up the jar from the electrolyte, rinse and remove the plate from it. After inspecting and eliminating damage, the contour is restored, searched. Sometimes the bank is replaced by a similar, from the non-working battery. The element is placed in place, the connection is restored from the car battery terminal.

The closed battery bank is the cause of its disposal. Sometimes a risky effect of exposure to the problem area by a pulse with a current of 100 A for 1-2 seconds is used. The location of the plates must melt - point contact and great resistance. However, it is worth risking if the battery is preparing to write off.

Methods of resuscitation of the automotive battery at home

The battery is one of the main devices of the car, which has a property to wear during operation. Therefore, from time to time, car owners have to change the battery due to the fact that it cannot perform its functions. More information about how the car battery is restored at home, you can find out below.

How to return to life and revive your car accumulator? This device provides continuous transmission of current to power the electrical equipment of the vehicle.

Accordingly, without this device, the normal operation of the instruments will be impossible, especially since the battery can no longer hold the nominal charge required for nutrition.

Not all Akb that do not work well, you need to throw away - the old battery can be tried to reanimate. This will avoid unforeseen financial costs.

Как восстановить аккумулятор автомобиля в домашних условияхDevice and designation of the components of the boutique

If we talk about acid-alkaline batteries, the structure is several positive and negative lead plates in sulfuric acid. Today, these type devices are the most common among cars used in the countries of the former USSR. Despite its prevalence, the resource of the battery life is lower.

Restoring the car battery with your own hands can be carried out using repeated recharging technology. This should use a short force.

The charge procedure using a charger of the recovery device should be interrupted. Starting from the first charging of the device and to the last voltage level, which is present in the battery, will gradually increase.

As a result, the device must stop discharged.

The charger restorative device should work with pauses, this will allow the potentials of the electrodes that are in the plates to be aligned. The recovery procedure itself for electrodes is safe. The use of a charger of the recovery device with pauses will provide the transition of the most dense electrolyte from the plates into the space between the electrodes.

Как восстановить аккумулятор автомобиля в домашних условияхRevealing traffic jams battery

As a result of the use of the technique of partial discharge, an increase in the capacity of the battery contributes to an increase in the density of the electrolyte. From the owner of the car it is required to wait for the moment to which the voltage will correspond to 2.5 volts, and the density parameter will correspond to the nominal one.

And in this case, we must not forget that the car battery needs a break, so the charger of the recovery device must be disconnected periodically. For complete resuscitation, the cyclic recovery procedure should be repeated 8 times.

It should be borne in mind that the current indicator should be less than 10 times compared to the capacity of the charged battery.

Replacing electrolyte

It is possible to restore the battery by replacing the electrolyte, this method has proved its effectiveness in practice.

To replace the electrolyte, the liquid from the design must be fully merged, after which the system should be washed with warm or hot water.

After flushing, several spoons of ordinary food soda are required - 3 spoons are diluted with 100 ml of water, while preferably use distillate.

Как восстановить аккумулятор автомобиля в домашних условияхBay of Soda Soda Battery

The mixed solution must be boiled and pour into the design instead of the fusion electrolyte, then leave the battery for 20-30 minutes. Then the fluid is drained from the device, and the procedure is still three times. After the last cycle, rinse with hot water again, preferably several times.

The method is relevant for many types of batteries. After the design of the washing, you need to pour a new electrolyte and put the battery for charging. The charging and restorative device must be included for 24 hours.

Then a cyclic charge of the device is performed - for 6 hours daily for 10 days. At the same time, we note that the memory itself should have such properties - the voltage parameter should be not more than 16 volts and at least 14. As for the current force, the indicator should be no more than 10 amps.

Reverse charging

How to recover a car battery? To do this, you can use the backling method. The house procedure is quite possible, but this will require a fairly powerful current source, for example, a welding machine.

The device that will be used should have a voltage not lower than 20 volts, and its current strength must be at least 80 amps.

After getting the equipment, you need to unscrew the plugs on top of the design of the AKB and produce a feedback procedure.

To perform this task, you need to connect the positive output of the charger to the negative battery terminal. The negative output of the charging device is connected to the positive battery terminal. If everything is done correctly, the procedure will increase the battery life resource for several years.

Note that during charging, the car battery can boil, you should not worry. The device charge procedure should be carried out exactly 30 minutes, no more and no less.

After that, the electrolyte from the design should be merged, and the device itself is washed with hot water. When all actions are performed, a new electrolyte can be filled into the design.

Upon completion of these actions, the battery will need to be connected to a normal memory (the current parameter of which should not exceed 15 amps) and charge the instrument over the next 24 hours.

Distribution of charge in distilled water

If you have not decided how to restore the battery and what method for this to use, we offer another option. Using it, it is possible to restore the efficiency of the device in less than 60 minutes.

If the car battery is completely discharged, it will need to be charged in advance. From the charged battery, it is necessary to completely drain the old electrolyte, after unscrewing the plug on the lid, after which the design can be washed with water.

As in the previous cases, it is better to use distillate.

After the battery is charged and the progress, the design should be pouring a special solution of the third-type trilon. The solution includes 2% of the trilder and 5% ammonia. Using fluid, the desulfation procedure is carried out, which is carried out no more than an hour.

When the battery is recovered, it will be possible to notice the release of the gas from its design, which is also accompanied by minor splashes that will appear on the surface. These gases are harmless to the body and human health, but it is better to put the battery in the ventilated room.

When the system stops highlighting the gas, this will indicate the termination of the desulfation process.

When actions are made, the design needs to be washed with distilled water - flushing is carried out several times. After washing into the device you need to pour the electrolyte of the corresponding density.

The device again needs to be charged and then you can consider recovered.

In general, the charge procedure and restoration of the rechargeable battery is not difficult, even an inexperienced car enthusiast will cope with it.

Not all modern batteries can be restored. Sometimes the device can be reanimated for a day, a few days or a week, and sometimes recovery allows you to ensure the performance of AKB for several years.

Much depends on how the battery was used, under what conditions, many electrical appliances were connected to it throughout the entire life.

An important role is played by the Terms of Use - if the device is often exploited in a discharged state, there is a chance that it will not be possible to restore it.

You need to check the moment on the use of the charger. The memory must be sound, otherwise it will use its battery breakdown. Our resource has already written about charging the battery and the use of special memory. In detail with the recommendations on this issue can be found in the article.

How to restore the battery: Desulfation of AKB

As is known, in the car, the battery consists of lattice plates made of lead dioxide or simply lead plates. A water-acid solution (sulfuric acid and distilled water) is chosen between the plates), which is called electrolyte.

During the operation of the AKB, there is a constant discharge / battery charge. At the same time, it is important to understand that in the process of discharge, some reactions flow, whereas in the process of charge others. The result is a gradual formation of deposits on lead plates (sulfate plates) of the battery.

When such deposits accumulate too much, the battery ceases to work normally. However, before changing the battery, you can try to apply methods to clean the battery plates from deposits. Let's deal with.

Sulfate plate acb and desulfation

If simply, lead and acid react with each other, which allows you to create an electrical charge. However, in the process there is a decay to certain elements that do not create electricity. These include water and salt.

Next, after the battery is discharged, the battery receives a charge from the generator or the memory (current supply to the electrolyte). In the process of charge there is a reverse reaction when water reacts with salt, which leads to the formation of acid and metal or metal oxide. In turn, these elements again have the ability to create electricity.

As already mentioned above, the complete recovery when charging the discharged battery does not occur and some of the salts of sulfuric acid remains on the plates. It is this process that is called sulfate. Salt on the walls of lead plates deposited as a result of a chemical reaction when the battery discharge, ultimately does not allow to contact lead and acid. After the lead sulphate becomes too much, the battery will stop working.

In turn, desulfation is the removal of sulfuric acid salts (lead sulfate or calcium sulfate) from lead plates of the battery. In this case, this can be done in different ways.

  • The first, desulfation of the automotive battery, which is the most correct, is the alternation of short and weak charges with minor and short discharges.

To implement such short discharge / charge cycles, you need special chargers for a car battery with a "function" of desulfation. In other words, the desulfation of the battery charger is the most gentle and efficient way.

At the same time, it is necessary to perform such a procedure with a certain periodicity during the operation of the AKB. It is also important to monitor the overall state of the battery, control the density and level of electrolyte, etc.

Available car battery recovery methods

So, besides the desulfation of the plates of the battery with the help of the memory, there are other solutions. Immediately note, such methods cannot be considered the best option, but in some situations they can be used.

For example, if the mechanical cleaning of the plates from lead sulfate will require the parsing of the battery, the extraction of plates and their cleaning, then the chemical cleaning eliminates the need to disassemble the battery. For such a cleaning, it is enough to open the covers on the banks, pour the solution - the cleaner and wait until it is cleaned with salt on the plates.

Of course, such methods are complex in sales and even dangerous (work with battery and acid involves compliance with the safety rules). However, if the battery is fully maintained with the electrolyte replacement, as part of such works, it is possible to hold and desulfate.

As for ordinary car enthusiasts, in practice, it is not all comprehensive to maintain the battery. In this case, it is much easier to purchase a battery charger with desulfation mode or a separate device for desulfation of the plates of the battery. Taking into account the fact that the second version is not suitable for everyone, then consider the method of desulfation of the usual memory.

How to carry out the desulfate battery charger

First, it is necessary to check the electrolyte density in the banks of the battery (norm of about 1.07 g / cm³), as well as the electrolyte level (if necessary, adjust the addition of distilled water).

Next, the main task is to charge the battery with small currents about 8 hours. There are 14 V and not more than 14.3 on the memory, while the current force is taking 0.8-1 A. If the memory does not allow you to set such parameters, you need to look for another charger for the car battery.

At the end, it is necessary to check the density of the electrolyte (nothing should change after the first check), but the voltage indicator should be about 10 V. If this is so necessary to turn off the battery from charging at least 24 hours.

Description of the Car Battery Restoration: Features, Types of ACB problems, where to start repair. Video recovery video.

Восстановление аккумулятора автомобиля – особенности работы

With the onset of cold weather, auto owners often begins to cause anxiety the state of the battery. But even if he stopped issuing the required current, it is not worth a hurry to send this unit on scrap metal - as practice shows, most of the worn acb after recovery can still have a significant time. While the new battery is not enough. The peculiarities of the repair of different types of energy-saving devices will be on.

What's wrong with the battery

неполадки автомобильного аккумулятора

The car rechargeable battery is usually a closed plastic container, inside which lead plates are positive and negative, which are a galvanic pair. As a rule, they are washed with sulfuric acid solution, also called electrolyte. The terminals of the electrodes can flow a current from the charger or generator. Well, when the battery accumulates enough ammers, it itself becomes the source of electricity spent on the start of the engine, the operation of the instruments and lighting.

The car generator during its movement replenishes the energy consumption, but it may be that the accumulated current is not enough at least in order to start the engine normally. What to do - time takes its own, and even with the correct operation of the machine, the battery plate is wear out.

However, in most cases, such ankb can be restored. There are a lot of ways to give the battery "second breathing", but in order to choose the most applicable, you need to determine the reason for the device failure to produce the desired amount of electricity.

Sulfate lead electrodes

Sulfate lead electrodes

Of all the "diseases" of the battery, this is the most common. The fact is that the work of the battery is usually accompanied by the formation of hydrochnya raids on its plates. If you do not bring the battery to a deep discharge, then when filling its energy, such deposits dissolve.

However, the causes of sulfate lies not only in extreme discharges. It can be caused by such factors such as a frequent incomplete charge or long stay of the battery in a discharged form.

To find out if the battery sulfate is amazed, it is necessary to unscrew its plugs and inspect the plates. Light raid with a brown tint is a faithful sign of such a process. Other symptoms This problem, which can be manifested in the maintenance of non-maintained acid batteries, are as follows:

  • When charging the battery scums after a while;
  • Fully charged battery is not able to promote the engine and sits in a few minutes from a regular light bulb;
  • White raid on the battery case.

Other malfunctions

Other malfunctions

The second battery malfunction is the destruction and sinking of their plates, which is easy to remove the black electrolyte color. If the damage is serious, then to reanimate this battery will be more problematic.

In addition, adjacent plates can be elementary to block themselves due to their deformation or accumulation at the bottom of the sludge formed from their squeezing. The contact of the electrodes is usually occurring in one of the batteries blocks. At the same time, in a defective bank, the electrolyte does not boil when charging, or this happens with the delay, and the voltage does not increase or grows barely.

If a thoroughly discharged battery is held for a long time on the frost, the acid electrolyte in such ankb can simply be frozen. The ability to restore the battery in this case will depend on the effects of low temperature effects.

Repair battery do it yourself: where to start

Ремонт аккумулятора: с чего начать

At the first stage of recovery, the battery should be cleaned its housing. The surface of the battery is washed with a solution of soda in order to remove the contamination and neutralize the electrolyte, often entering the lid.

Retaining with battery terminals is removed with small emery paper. By the way, it is precisely the oxidized surface of the contacts may be the cause of unstable battery operation. Therefore, after their purification, the car battery will be experiencing in action.

Desulfation by charge-discharge

Desulfation by charge-discharge

For this purpose, the "cedar" automatic charger is coming in the sale or similar. Such gadgets are independently started and stop charging depending on the settings.

The recoverable battery is pre-filled with electricity to all available capacity. After that, the charger with a swivel lantern connected parallel to the light bulb runs 3-5 days in training mode, which consists in a minute charging and a dechecond discharge. After such a "rich" battery should be charged finally.

Along with industrial, car enthusiasts for this method use and self-made units, alternating short pulse charge current with small discharges. If neither the serial, nor self-made specialized charger in the arsenal is available, you can try to desulfate the battery manually.

In this case, the usual charger with fixed settings exhibited by 14 V and 0.8 A, connects to the battery for 8-10 hours. After this time, the voltmeter should show the result of filling the battery of the battery. The day is given a battery for rest, and again charging, but already with a current of 2 a, after which the voltage with the density should increase a little.

The lamp is then connected to the battery, and for 6-8 hours, the voltage reduction is controlled by a voltmeter to 9 V - it is less desirable not to allow. And hereinafter - Repeat cycles before receiving voltage from battery capacity in 12 V and normal electrolyte density:

  • Charging with a current by 0.8 A;
  • day - on vacation;
  • again charging current in 2 A;
  • Discharge with a light bulb.

Depending on the state of the battery, it takes it to a feeling in such a way to two weeks.

Replacing electrolyte with your own hands

Replacing electrolyte

It happens that the substance in the banks of very old, long-not used batteries becomes muddy or black. The same phenomenon occurs with a short circuit, which can be detected in the absence of gas release from a particular container when charging. The contaminated electrolyte is better replaced, and if the battery "Korotit" due to the deformation of the decisions, then physical intervention is required for its recovery.

On batteries, where each bank is installed separately, it is relatively simple: a short-circuit container is revealed and new plates are mounted. For modern battery with elements placed in a common case, such a repair is difficult, but also possible.

From the battery, subjected to a short circuit, first merges the acid by pulling it with a pear. You can free from the liquid only a defective bank, but it is better to the entire battery, since the fresh electrolyte does not hurt her. Next, the battery should be filled with distilled water, slightly shake the housing and dramatically drain it. You should not turn over the device not to clog the plates with sludge. And so as long as the flushing fluid becomes clean.

Well, for the exclusive repair, a more radical way is seized with a short circuit. Thus, under it in the bottom of the battery, a small hole with a diameter of 4-5 mm is drilled, through which the liquid merges with the sludge, and the compartment itself is washed with distilled water. Then the artificial hole is closed with plastic with a soldering iron. If the plates of the battery are intact, it will be enough to add the electrolyte according to the following method:

  1. Pour an acid density 1.28. For two days before that, the electrolyte can dissolve a special additive for desulfation.
  2. A day you need to wait for air to come from the battery.
  3. Charging the battery current 0.1 A to 14-15 V and complete density recovery. At the same time, you need to trace so that there is no violent boiling of liquid and strong heating of the case. In the case of which the battery is better to turn off, give it to cool and then continue the process of filling the battery with energy.
  4. When the area will show the desired value, the current should be reduced for two hours. If during this time the electrolyte density will not change significantly, charging stops.
  5. Discharge current 0.5 A to 10 V. If the voltage decreased to this value earlier than after 8 hours, the cycle is repeated. Otherwise, the battery is simply charged to the nominal indicators.

How to remove the plates of the battery

How to remove the plates of the battery

Even if the battery is insecured, replaced the plates in the event of a short circuit in it, you can still. To do this, on top of a faulty can, pre-released from the acid, is cut off plastic, and jumpers leading to neighboring containers are disconnected. The block is dismantled from the battery and is rinsed well in the water, getting rid of electrolyte residues.

Further task is to find the reason for the closure, for which the plates and dielectric should be examined. Damaged electrodes can be replaced with similar integers from another battery.

After troubleshooting, the bank must be rinsed, thereby freeing it from pollution, and return to the place. The jumpers are restored, previously removed part of the battery cover is mounted back with the help of glue, epoxy resin or plastic melted with a soldering iron. The electrolyte is poured, the battery is charging.

Radical stirring

Радикальная переполюсовка АКБ автомобиля

When in one of the six cans of the battery there is a significant reduction in voltage, when charging the pole in it changes their sign. Such a phenomenon provokes a chain reaction, leading to similar metamorphoses in neighboring containers.

Surprisingly, this is the case when repairing the product helps the fault artificially created in it. The ignition allows you to largely clean the plates from sulfates and restore up to 80% of the initial battery tank.

However, such a radical approach should not be applied if :

  • electrolyte color in banks - black;
  • The battery has a short circuit;
  • Electrolyte density is insufficient.

Of course, the method of ignition is different as a barbaric you will not name, but if other ways to restore the battery did not lead to the desired result, you can also try such technology. If the battery does not work, it will not be worse for her anyway.

So, first of each bank of the battery accumulator, the electrolyte is selected and the indicators of this instrument are determined, based on the state of the containers. Among them are completely inoperable, it is usually a bit - one or two. And to restore the capacity will have to, by and large, only these elements. Moreover, the ignition can be carried out at home, without disassembled the battery.

The main stages of the process:

  1. The discharge of the battery "to zero" with some load - for example, a car light bulb. If some voltage remains, a short closure of terminals is applied.
  2. In the rupture of the terminal with the minus sign of the charger, the ballast resistance is included - for example, a resistor by 50 kΩ, to protect the battery plates from a short circuit.
  3. Connecting the charger wires to the battery in reverse polarity: positive - to "minus", negative - to the "plus".
  4. Charging the battery current, the force of which is 10% of the capacity of the AKB, followed by a decrease in this value to 2 A.
  5. After boiling the cans, charging continues two more hours.

The electrolyte density is re-checked. In service banks, it should be less, and in defective - to increase. Using the closure of the terminals, the battery is subjected to a deep discharge, after which the battery is connected to the charger already according to standard polarity and the above-described cycle of energy set passes. For reliable recovery, the battery is recommended to swing twice.

Conclusion

Of course, restore the battery at home is quite possible. However, it should be noted that the sulfuric acid is in it and the gases formed in this unit are unsafe. Therefore, when performing work related to disassembly of the battery, you need to wear gloves, and the room should have good ventilation. And in general, to repair the battery is better in the fresh air.

Video recovery video:

Since not everyone can use the battery correctly, there are various problems in the form of breakdowns. Signs of malfunction of the battery are extensive and different, so it is quite difficult to identify the true cause of failure. However, even identification of the cause does not guarantee the full battery recovery.

ACB faults subject to recovery

The main types of faults that are not critical:

  • Plate destruction
  • Short circuit.
  • Sulfate.
  • Blowing electrolyte.
  • Permanent battery discharge.
  • Surprise.

Eliminate such faults can be if you do everything according to the instructions.

Is it possible to restore the dried acb

To revive dried acb, but it will be necessary to use distilled water. The description of the process, how to fix the battery:

  • So, you first need to take the battery, then using a screwdriver to open a plastic cover.
  • Next, remove the caps and in each hole, with a syringe, pour 3 ml of water.
  • Then put the battery for charging. Pick the voltage until the current appears. If the battery is in a bad condition, you may not see the current for 15-30 minutes.
  • Voltages need to be raised until the current of at least 10-20mA appears. Having achieved such values ​​should be careful, since the current will gradually grow and have to regularly reduce the voltage. When the current comes to 100m, do not reduce the voltage. And when the indicator comes to 200mA will need to turn off the battery for 12 hours.
  • Further put the battery for charging, the voltage should be so that the charging current for our 7Ah aggregate was 600mA. Support the specified indicator of exactly 4 hours. After recharging, about an hour, the battery must be discharged to 11 volts, it is possible to do this with any 12-volt lamp (for example, on 15wat).
  • After the battery is discharged, it is necessary to charge again with a current of 600mA.

It may not be possible to return the nominal capacity, since the plate sulfate has already affected the resource. But the battery can be further operated without any problems.

Methods for restoring alkaline and acid batteries

Alkaline and acid acb are returned to life in different ways. We will consider the repair of old disk alkaline batter D-0.55. And how to repair the battery:

  • If the batteries are present in a set of some battery, they will have to be divided. Wrap in a package of polyethylene and put in the freezer for several days;
  • After the freezer, immerse them into a container with water and put on fire. It is necessary to wait until the fluid boils and boil them about fifteen minutes;
  • Then cool the batteries without removing from the water. Then remove them and rinse with cold water;
  • Next, put the battery on the plate of metal and warm in the stove for 5-10 minutes at a temperature of 60 000 degrees. Give batteries to cool;
  • The last step is charging alternating current. To do this, place the batteries back to the set or charge them separately. Charging time 30 minutes, and current - 0.2 * s.

After recharging alkaline batteries, wait a couple of hours, and the recovery process ends with usual charging in the simple memory. This is how to revive the battery without any problems.

The revival of lamellast alkaline batteries with sulfuric acid. There are many ways to restore lamella alkaline acb, among which you can select the easiest and most popular option:

  • Battery discharge;
  • washing with distilled liquid;
  • Activating type of additive;
  • Removal of unnecessary crystals and impurities.

This method is complemented by electrolysis in water and control cycles in the alkali solution. And now consider the standard method for restoring lead acid accumulators. And how to return the battery to life:

  • First, it is necessary to drain the entire electrolyte from the battery, washed with hot water, and then a warm solution (3 teaspoons of soda per 100 ml of water) leaving a solution in the battery for twenty minutes. Repeat the procedure, and at the end will pour a new electrolyte.
  • Next, you need to charge the battery (spend on this day), and then, for 10 days, 6 hours a day.
  • The second way is the reverse charge, first need a powerful voltage source, for example, a welding unit, recommended current - 80 amp voltage 20 volts.
  • Further, the rally is performed, that is, plus to minus, and minus to the plus, and for 30 minutes you need to boil the battery with its native electrolyte, after which the electrolyte must be drained and rinsed with hot water battery. Then pour the new electrolyte and, by observing a new polarity, over the day, charge 10-15 amps current.

Repair completed, so you learned how to restore acid battery. These ways are so simple that even a child can cope with repair.

How to reanimate old or non-servant batteries

Many people think about how to restore the maintenance-free batteries old. The full revival of the AKB is available in the presence of equipment. There are several ways to resuscitate batteries:

  • multiple type charge or discharge with low currents with low complexity electrolytes;
  • String or welding of cracks in the battery case;
  • repair terminals.

To revive, the battery case must be opened. Typically, the top wall of the battery is pricked with the basis of the hot "method. Reheat heating can cause deformation. Sometimes the lid is snapped by gaskets from rubber in the appropriate groove.

Attention! When swinging or closure, the plates cannot be connected to the battery to charging. For desulfation of the plates, you need to buy a special additive to electrolyte:

  • In the fresh electrolyte dissolve the additive for 2 days (much depends on the volume of the battery).
  • Electrolyte is poured into the battery.
  • With the help of the area, the density is determined (n. - 1.28 g / cc.).
  • Tubes are unscrewed.
  • Include charging to pass the cyclic steps "Charging-discharge". Current value - 1/10 part from max. permissible. The battery should not be heated and boiled. If the density has not changed for several hours, the battery is charged.
  • To change the electrolytes, purified water is added to the liquid. Nominal type of density value - 1.28 g / cc.
  • KB discharge. To do this, the load is connected, and the current is limited to 1 or 0.5 amps for 6 volts batteries. The current is multiplied by the discharge time to determine the value of the tank. To achieve a minimum, you need to repeat the step "charge-discharge".
  • At the end, additives are added again and fasten the plugs.

Quick method of restoring maintenanceable battery:

  • The battery is charged to a maximum;
  • pour an old electrolyte;
  • The battery is washed with distilled liquid (how to rinse the battery know almost everything);
  • A trone b and ammonia solution is added (5%); for 30 minutes, it is expected.
  • If required, repeat the desulfation procedure.

The work is completed. Here you learned how to reanimate the battery.

Features of recovery after deep discharge

The deep discharge of the battery is the process of identifying a minimum charge, after which the electrical chain is blocked by means of a special controller. If you do not perform the operation on the launch, the battery will continue to fall, and then it will stop holding the charge at all. And how to make the battery hold, recovered? To restore you will need tools for checking voltage and current, a six or twelve volt adapter, a stroke resistor.

Specialists argue that the low level of battery level negatively affects the state of the battery. Even after repair, most likely, partial degradation will be detected and a decrease in the tank will be revealed. If the battery does not start at all, then you need to do the following:

  • First you need to make a standard charge for 30 minutes.
  • If you can't do it, you have to disassemble the case to access the terminals.
  • Then it is worth to isolate the scheme of the unit, for this you need to disappear acB from terminals.
  • After determining the polarity of the battery terminals. It is important that because of this process, the battery can stop working.
  • At the end it will be necessary to submit voltage within 4.2 volts. It is important not to exceed the indicators.

If you are all done correctly and consistently, the battery must turn on and start working. It is easy to understand how to restore the battery, it is difficult not to move away from the rules.

What can not be done if the battery went into a deep discharge?

  • Do not try to connect the device to a more powerful charge. Most often, due to this, the controller of the device begins.
  • It is forbidden to connect the charging directly to the terminals, because this power supply will supply more voltage than necessary.
  • If you have a charging having an adjustable voltage, then under no circumstances connect it to the terminals without determining polarity.
  • If you failed to start the battery, then it is better to replace it with a new one.

If we consider the above recommendations, you can solve a lot of problems.

Clearing banks in battery

To restore the unit, you need to find out what the bank is closed. There are two ways: technical and simple. The first method involves performing the measurement of the voltage of each bank using a new tester - a multimeter. This technique is relevant for old batteries, because earlier jumpers can be in products from above.

New devices are filled with plastic, so the second method provides for the measurement of the voltage of the entire device. If, after complete charging, the voltage ranges in the range of 10-11, the bank closed. To determine the defective bank you only need to find a section that does not release gas bubbles.

The second method is simple: the electrolyte color inside the sections indicates their state. So, if the composition is very dark or black, it means that the separation does not work. After identifying a defective bank, you can proceed to repair:

  • unscrew the section cover;
  • Drain the electrolyte from the bank;
  • Cut plastic from above around the section;
  • Disconnect the jumpers from neighboring compartments;
  • Remove the package of plates, rinse the liquid;
  • Determine the location of the closure:
  • Examine each plate, use dielectric;
  • Rinse the deposition department;
  • Immerse the packet of plates into the section;
  • perform a soldering jumpers to neighboring departments;
  • Fill electrolyte;
  • Screw the covers;
  • Perform a solder of the cut plastic places by epoxy resins, adhesives.

At the end of the procedure, you must recharge the device. More than 85% of cases, the voltage level comes to the desired mark. The battery is ready to use.

Battery capacity recovery features

Even if there was no deep discharge, but the battery operates in a dilapidated state, the sulfate of the plates will occur sooner or later. The larger and dense precipitate, the lower the concentration of the electrolyte, the capacity of the battery capacity of the battery capacity is to restore the electrolyte density and the battery ability to receive a charge:

  1. Disassembly of plates and their mechanical cleansing is used, unless otherwise disposal. Holes are cut into the case cover, plates are removed. Distilled liquid wash cavities and plates. The tightness of the design is restored, the electrolyte is poured, charging is performed. But since the plates are easy to damage, restoring the battery in this way - the work is complex.
  2. Chemical dissolution of crystals can revive the fully-stop battery. The basic substance is the trilon B solution. It is necessary to discharge the battery, pour the electrolyte, rinse everything inside with distilled liquid. In pure banks pour a 2% trillion solution b and 5% ammonia per volume. Within an hour, the boil and formation of gases will be observed. It is likely that the solution will be required repeatedly if the reaction continues. After draining the solution, wash it with water and pour fresh electrolyte. Carry charging.

Tips for restoring terminals

With permanent operation, a large snow-white flare appears on terminals. The reason is an oxidizing process that corps the metal. It is forbidden to do when oxidizing the battery terminals:

  • use for cleansing vaseline, as it negatively affects conductivity;
  • Processing elements with gasoline, as it is dangerous.

Terminals are usually restored by soda. The process occurs as follows:

  • For soda solution, 1 tbsp will be required. Soda and glass of hot water.
  • First, the engine engine must be drowning, weaken the nut and remove the terminals.
  • Then you have to get the battery and check whether there are cracks, leakage.
  • Then, using an unnecessary brush for teeth, moistened in solution, carefully process the terminals.
  • To eliminate the corrosion flush from the battery cables, place them in hot water.
  • Battery Wash with cold water and wipe dry.
  • At the end of the terminals, handle with protective lubricant, and attach back.

Attention! If the raid on the terminals is too solid, to repair, take a sandpaper and a sharp knife. However, act carefully. Before checking the battery, you should make sure that all the elements are reliable.

With a short circuit, the Accord terminal melts and loses its original shape. For its recovery in living conditions, sweeters are used:

  • Cleaves remove the melting traces.
  • The remains are cleaned and deserve a soldering iron.
  • For a new terminal, a tin type is suitable.
  • Prepared by the solder is slowly filled with a form, slightly mixed.
  • Form cutter from a pipe or coofer.
  • The workpiece is treated with a mill.
  • The shape of the terminal is changed by sandpaper and file.

Important! In automotive services can restore the old terminal. To prevent the battery breakdown, it is better to make a new one.
