Is it possible to revive the battery of the car. How to charge maintenance-free batteries? How to reanimate the battery? Batteries for car

17.11.2019

Hello everyone! Many motorists are familiar to the situation when their battery is hopelessly losing the container. But you do not need to rush to the store for a new one. After all, the old battery can still be returned to the system. You just need to know how to restore the car battery. We will talk about it about this.

Why battery breaks

Before you understand how to restore car batteryLet's determine the reasons why he fails.

Causes of capacity loss:

sulfate plates - The most common malfunction. Diagnosed simply - the battery quickly loses the charge. It is usually possible to make the restoration of the container;
one of the cans does not work - Most often occurs as a result of short circuit between contact plates. In this case, the closed bank begins to overheat and boil during operation by car. And in the battery, the capacity is strongly sitting - it is often not enough to start the car;
sowing coal plates - The electrolyte becomes muddy or black. In this case, the battery is usually not subject to restoration;
frozening electrolyte - If you use a low-density battery in severe frosts - the electrolyte will freeze. As a result - the case can crack, and the plates are deformed. In this case, it will definitely have to buy a new battery - the battery will not work.

If we say simply - the reasons for the premature failure of the battery two. Either the manufacturer's marriage, for example, poor-quality coating of plates, can lead to closures in banks. And the second reason is incorrect operation. Most often, resulting in plate sulfate.

Since this is the most common malfunction, let's consider it in more detail. It is worth noting that the recommendations on the restoration of AKB are referred to as acid batteries. Alkaline type is repaired differently.

What is sulfate plates

As you know, the principle of operation of an acid lead car battery is based on the use of liquid electrolyte. And its basic characteristic is the density that should be within 1.25 g / cm3 - 1.27 g / cm3 for the charged battery.

In the process of charging on lead plates, active substances accumulate, and the electrolyte density increases, because The distilled water is absorbed. And when the battery is discharged, its density drops, distillate is distilled, and sulfuric acid is absorbed.

Also, in the process of energy absorption, crystals begin to appear on the plates - lead sulfates. Under normal operation mode, i.e. When the battery works cyclical - this phenomenon does not harm it. With the next charging, sulfates are simply blurred.

But, in the work of the battery there is an unpleasant dependence:

small discharge - small crystals are formed, which are easily dissolved;
deep discharge - large sulfates appear that do not dissolve in electrolyte.

Thus, with incorrect operation of the battery, the surface of the plates is reduced by sulfate, and its container falls.

Desulfation of battery

Restoration of automotive batteries with a fallen container as a result of plate sulfate is made by such methods:

physical cleaning of plates;
chemical cleaning;
desulfation with help charger.

Let's look at these ways in more detail.

Physical cleaning

This is a fairly extreme method. The recovery of the battery is reduced to the excavation of the packages of contact plates and their manual cleaning.

How to revive the battery:

the windows are cut out in the top cover - it is best to do this with a thin soldering iron or a hot knife - in banks will not fly garbage from plastic. Although it is possible to use the electroltrol bike;
the plates are removed through the holes and cleaned;
after that, they need to be thoroughly rinsed with distilled water;
inside the cans are also washed with distillate;
contacts are placed back, the windows are sealed;
the battery poured the electrolyte to the level;
The battery is postponed.

On the one hand, everything is simple. And on the other, there is one big but - lead plates are very fragile, especially after a long use. Therefore, the likelihood is great in the process of cleaning. It is possible to repair your battery this way only in the case of its complete hopelessness.

Chemical method

For this, a special chemical solution of the trilder V. Battery resuscitation does not take much time - desulfation takes place in 1-2 hours. The only difficulty in the preparation of the solution itself.

What you need to do to restore the capacity:

The battery is fully charged;
electrolyte completely merges from it;
banks are well washed with distilled water;
a trilon solution is poured into the battery in and left for about an hour. The process of dissolving sulfates will be accompanied by gas dividing and boiling. When the reaction is over - the operation can be repeated;
the battery must be rinsed again with distilled water, after which the fresh electrolyte of the desired density is poured into the jars;
The battery is postponed.

This restoration method is quite effective after deep discharge. But there is in it and cons - during manipulations from the battery, the pieces of lead can get between the plates - as a result of banks can be shorted.

Desulfation of AKB using a charger

The most common method of repairing AKB at home is the use of charger. The process is simple, but long-term.

Repairs can be done in several ways, but their essence is reduced to the alternation of a complete charge with a discharge. Those. Sulfates dissolve naturally. Let's look at how to restore old battery With the help of a charger.

By the way, first of all, you need to check the level of electrolyte. If it is below the norm - be sure to add distilled water. Pouring electrolyte is impossible - in the process of desulfation, its density will rise, and it is a plates.

Pulse charge

To do this, you will need a charger for AKB, which can work in a pulse mode and equipped with the function of desulfation. It connects to batteries and everything. The device itself makes desulfate.
The principle of operation is quite simple:

the battery is charging on a small current for 10 minutes;
then the load is fed to it and it is discharged for one minute.

The time interval can be different, but the essence does not change. This option can be used in rigorous cases. Another minus is the price of the device. It may be higher than the cost of the battery and varies in the range of 5-10 thousand rubles.

Restoration of ordinary charger

The easiest and most affordable method. Moreover, the usual charger has most motorists. Let's deal with how to restore the battery in this way.

Sequencing:

Akb needs to be charged on low current. We put on the charging 14 V and 0.8-1 A. The battery must be charged for 8-10 hours. If it starts to boil - you need to reduce the current;
the result of such a recharging will be a small voltage rise in AKB;
Akb is removed from charging and defended during the day;
after that, it is necessary to slightly increase the current - up to 2-2.5 A and leave the battery to charge for 7-8 hours;
as a result, the density and tension should rise a little;
the battery is discharged to 9 V. To do this, connect to the terminals of the car lamp far Light And wait until he sees;
the cycle is repeated until the voltage is obtained in 12V and normal density.

The method of course is not fast, but quite efficient and allows you to revive fairly running batteries.

If the bank closed in the battery

This breakdown is very detrimental for the entire battery, because Disabled bank has an impact on working. The fact is, while charging the battery, the voltage is evenly distributed between all the packages of the plates. And when one bank does not work, too high current is fed to the rest. As a result acid battery It starts to boil, which causes the sulfate of the plates.

Let's figure out how to restore the car battery with a non-working bank. In fact, not everything is so scary:

it is necessary to find out which bank is not working. When charging, it can boil, or vice versa - others will boil, and the closed will be dead;
the entire electrolyte is poured out of the bank;
in the upper cover the hole is cut;
lead plates come from banks and are well rinsed in distilled water;
now you need to find the cause of the closure - for this plate carefully examine. By the way, if the Akb is old - the cause of the closure can be in the sediment at the bottom of the bank. Therefore, if it is - it needs to be washed;
after, washing and inspection, the package is placed back to the jar, and the cover is searched.

If you do everything carefully - the high probability that the battery can be repaired. It is important to remember that it can not be strongly pool and turn over the legs - the other plates can be closed.

If the battery is non-servant

Restore the maintenance-free battery is much more complicated - there are no access to banks. Those. There is no possibility to check the density of the electrolyte. In some forums, the question can be reached before the internal batteries, they advise to drill the top cover.

It is better not to do this - in such batteries, a gas feed system is arranged in the upper lid. If it is broken - the battery will not be exactly repaired. So let's consider how to correctly restore such batteries:

first, you need to determine the level of electrolyte in banks. Make it can be translucent of their bright flashlight;
if it is below the norm - in the upper part of the battery (above the electrolyte level) there is a small hole - 2-3mm in diameter;
through it the syringe poured distilled water;
holes are searched.

Also, cyclic charge and discharge helps to restore the tank.

Helium battery

Restoring gel batteries is somewhat simpler - nothing to drill. This type of battery cannot be restored in two cases:

destruction of plates. Usually occurs during the long-term use of AKB at high temperatures;
battery bloating.

Unlike acid, helium batteries, most often fail completely.

What needs to be done for resuscitation:

the top cover is removed;
under the lid there are rubber caps - they also need to be removed;
it is advisable to take a flashlight and enjoy the inside of each bank. If the surface of the plates is light and normal form - we go to the next step. And if inside the black tube, the battery can be thrown out - it will not work back to life;
inside each jar is added two cubes of distilled water and the battery is sealing. It is important to trace so that the top cover of the village is tight.

If he has greatly lost the capacity - it can be reanimated, driving cyclic charges and discharges. This procedure is described above, the main thing is not to discharge the acb below 10.5 V.

Thus, restore the battery with your own hands is quite possible. Of course, it will take time, and in some cases the result may not be very. But, nevertheless, it's worth trying. A new battery you will always have time. In addition, dried accumulators are restored by the same ways.

On this, I hope the material was useful, and you can restore your battery. Do not forget to leave your comments.

Car owners with problem accumulators have difficulty while starting the engine. After all, only a serviceable battery gives the necessary current. After reading the article, you will learn what kind of battery faults are whether they can be fixed and learn to restore the performance of this device.

When the battery is required

The first feature that the battery is not all right - the difficulty with the start of the engine. Competitive and fully charged battery without difficulty crankshaft Motor at temperatures from +50 to -30 degrees. If this happened, measure the voltage at the battery terminals.

When the ignition is turned off voltage should exceed 13 volts, and during starter operation do not fall below 11 volts. If the voltage is in order, then the problem is not in the battery. If the voltage does not match the above, the verification of this device is necessary.

How to check battery - Is it possible to recover?

First of all, remove the battery from the car and wipe off with a clean cloth. Put it on the table and carefully inspect. Perhaps in one of the walls of the body, the crack, through which the electrolyte is eliminated. Do not forget to examine the bottom of the battery (for this slightly tilt it). If there is no crack anywhere, remove the plastic bar, which closes the fuel holes. Look in them - the electrolyte level must be 1-2 below the battery lid.

If the electrolyte is below, it may not cope with its work, which is why the charge voltage is higher than the required. As a result, the electrolyte boils and the pairs goes through the breather (small holes with a diameter of about a millimeter) of plugs of the filthy gorlovin.

In the nearest store of auto parts, buy a device called "Aareometer". Without it, you will not be able to estimate the state of the battery. The density must be within 1.22-1.3 g / cm3. If the density is below, the battery must be charged. If the density is stacked in these values, more serious diagnosis is needed. It is necessary during the topping of distilled water to restore the electrolyte level.

Video - how to raise the density of the electrolyte

Restoring car battery

Making sure that the battery density is in order, prepare the plastic pelvis in which the electrolyte will be merged. This operation is performed in rubber gloves, protective glasses and respirator, because sulfuric acid not only leaves chemical burns, but also distinguishes poisonous substances. There are two ways to drain the electrolyte - the slope (and then turning) the battery and using rubber pear, which can be bought in some stores selling auto parts or medical supplies. The first way is faster, second safe.

Place or remove with 2/3 electrolyte with a pear. Wipe the battery with a clean cloth to remove the residues of the acid, then tighten the plug. After that, lift the battery above the table and swing to the left - right. It is necessary to raise from the bottom of the sediment, because it is precisely on it that you can determine the state of the plates. Immediately after this, carefully pour the remnants of the electrolyte in the pelvis. If the electrolyte is clean and does not contain any solid fragments, then everything is in order with the plates.

If there is a lot of fine sand or opaque suspension in the electrolyte, then the plates are slightly worn, but well-efficient. If the electrolyte includes solid pieces of over 1x1 millimeter size, the plates are partially destroyed. Try to determine which holes contaminated electrolyte resulted out. If from one, then the battery makes sense to restore. If from two or more, then it will be cheaper.

Battery repair

Determining the electrolyte with large fragments of plates, wipe the battery with a clean cloth to remove the acid residues. To restore performance, you will need:

First of all, it is necessary to determine the boundaries of the damaged bank. Carefully inspect the battery lid, on which terminals and filling holes are located. In most cases, it is viewed by transverse partitions that share batteries banks. Determining where the walls are located, retreat from them inside the cans of 1 mm and spend the line.

Using a hacksaw or a grinder, cut the battery cover on these lines. This will allow the borders of the side walls. Having defined them, retreat 1 mm, lifting the lines and using the cutting of the canvas for the hacksaw or the grinder. Run the battery cover.

Cause of malfunction rechargeable battery The car is most often the sulfation and the destruction of the plates as a result of a deep discharge, a long reloading or crystallization of the electrolyte at minus temperatures. In the warranty card and the car operating manual, most likely, at such a case you will find only the recommendations for replacing the Akb new. Nevertheless, you can try to reanimate the power supply by proven methods.

We raise the container and density

The main method that in various modifications is used to restore the battery is a multiple charge of a small current (usually such a recommendation can be found in technical literature). Due to the sulfation of lead plates (their surface is covered by a tap, which prevents normal battery operation), the battery capacity is significantly reduced. Charging is carried out quickly, but the discharge also occurs as quickly. In a short time, the AKB stops taking the current from the charger, and the pause is made, after which the cycle is repeated.

Force charging Tok. Must be low ¬- 4-6% of the nominal capacity. For example, if you have a capacity of 60 Ah, then the allowed current will be not more than 3.6 A. as a rule, the time of one charging cycle is 6-8 hours, a break - from 8 to 16 hours. The total number of cycles charge-break - 5-6. The cessation of restoration work is relevant if the electrolyte density has become normal for this AKB, and the magnitude of the voltage of each of the sections varies in the range of 2.5-2.7 volts.

How to restore the car battery at home

A method that is suitable to more motorists who have no opportunity to wait for the result for a long time, consists in dissolving sulfates by washing with a special composition:

Charge the battery on all available capacity.
Drain the electrolyte.
Rinse the internal surfaces of cans with distilled water 2-3 times.
Fill an ammonia solution of trilon b (2% trillion b + 5% ammonia).
Leave the battery in this state for an hour (the end of the reaction will indicate the termination of active gas release).
Repeat desulfate in case of insufficient cleaning of plates from the plaque.
Rinse the battery with distilled water 2-3 times.
Fill the electrolyte of the required density.
Draw an AKB in the standard way.

The washing option easily lies in the following:

Drain the electrolyte.
Rinse the inner surfaces of the hot water battery several times.
Twin-three times rinse the plates with a shutter speed of 20 minutes with a cleaning solution with a cleaning solution and 3 teaspoons of technical (can be edible) soda.
Rinse the inside a couple of times with hot water.
Fill the fresh electrolyte and charge the battery during the day.
After the discharge of the AKB in the process of driving a car daily charge it within 6 hours over the next 10 days. Approximate charge time - 6 hours at voltage

14-16 volts and charging current no more than 10 amps.

Is it possible to reanimate a non-maintained acid battery

A reliable way to resuscitate the maintenance free car battery is very simple, but requires patience. First you need to pour the entire electrolyte, replacing it with the usual distilled water. Terminals are connected in the usual order to the charger on which the constant voltage of 14 volts is exhibited. After a couple of hours you need to listen to the processes occurring inside. There should be gas emission. If it is intense, then it is necessary to slightly reduce the voltage of the charging current. Thus, it is necessary to achieve a moderate, but stable gas formation.

In this state in two weeks, the battery will make a weak electrolyte from the water as a result of its reaction with lead sulfate on the surface of the plates, which will be gradually converted into sulfuric acid molecules. After the specified time, the contents of the cans are replaced by water again, from which a new electrolyte should be obtained within 1-2 weeks under the action of already tested current. At the end of the desulfation, the electrolyte of weak density is subject to replacement with a normal electrolyte. The final stroke of the recovery will be recovery in accordance with the standard parameters for this battery.

Correctly eliminate short circuit

It happens that the problem of the discharge of the battery became a consequence of a short circuit in one of the cans. In this case, the electrolyte charge in the problem section becomes impossible. The only output is to eliminate the closure zone by burning it out of the current. It is enough to connect terminals, for example, to a welding machine with a rectifier diode at the output to give a current of current to 100 and more amperes. Close the chain will be enough for a couple of seconds. This is enough to eliminate the place of contact of the plates as a result of its critical overheating.

Reverse charging

The welding machine can also help when restoring the battery by reverse charging. Polarity should be perceived in this case with accuracy to the opposite: "plus" the power source connects to the "minus" of the battery, "minus" - to plus Terminal. The voltage should be 20 volts, charging current is 80 amps or more. With the plugs of all the cans of all cans serve. The battery should be actively boiled for half an hour, after which the electrolyte should be merged. After washing acb hot water, you can pour a normal electrolyte and charge the day battery. But there is an important nuance: Terminals have now changed polarity, so the "plus" of the charger is installed on the "minus" of the battery, and the "minus" goes to the former "plus".

If the above methods do not help solve the problem or there is no possibility to wait, you will have to buy a new battery.

Automakers seek to ensure a decent life of their products in general, as well as their individual elements. However, there are ways to help expand the framework established by these companies. An example is the reanimation of the main electric device In a car. In the article, tell me how to restore the car battery so that it will work out a few extra months or not.

Buying a new battery in this case is not canceled, but only postponed for this period. For experiments, initially high-quality batteries are suitable. Related materials to help "revive" the developed unit are available for any car owner.

When the battery is subjected to frequent complete discharge and a long-term idle position, then with such an operation, the main "disease" occurs - sulfate plates arises. The consequence of this process is a noticeable decrease in capacity. Because of this, such a battery cannot scroll through the starter during the start of the motor.

Sulfate plates AKB

You can learn about the starting sulfate in several signs:

increased voltage on terminals;
noticeable heating of plates during operation;
sometimes electrolyte boils;
the charge capacity is reduced.

Another cause of breakage can be the destruction of plates, which leads to a short circuit between them. Sometimes the full separation of the plate happens from its place. The reason for this damage can be an excess of the voltage filed for the charge of the ACB with a lack of electrolyte in the container.

It is necessary to know that both insufficient and redundant charge can lead to the destruction of the automotive battery.

After carrying out repair work With the battery to revive the car battery, it will be necessary to get rid of the source of destruction of the electrical element.

External damage to the battery

Before the start of the elimination, we define a variety of troubleshooting and the possibility of eliminating them. Oxidation of terminals is present as external faults. Due to the coating with a layer of scale, there is no high-quality contact between the surface of the battery electrode and the wire in contact with it.

Throwing the surface can be restored the output electrical characteristics of the battery. Sometimes the terminal is attached quite tightly, bins to the electrode, so it is necessary to unwind the connection and control the presence of a good pairing.

The second most popular external problem is damage to the battery case. This is due to external mechanical damage or due to internal faults. Restoration of the car battery and close up the platforms are possible only on the serviced battery. For this, the contacts are folded, the battery is removed, the remnants of the electrolyte merge and the outer wall is soldered with plastic marks. You can check the tightness using distillate. Only then in the container, fresh electrolyte is poured.

Domestic breakdowns of AKB

The main problem that spoils the battery from the inside is the coating of the plates of the salts of the reaction of acid and lead. They prevent the movement of charged particles from one electrode to another. In parallel, resistance is growing, which leads to a decrease in the total battery capacity. Early periods of such a process are reversible, but if the reaction has significantly damaged the plate, the renewal of the aggregate is impossible.

Electrolite density measurement device

Sometimes it is possible to swallow particles from the plates leading to the closure. If this happened not so long ago, it will help the washing of the inside with distilled water. In order not to get the inflatation of the housing from strong long frosts, you should not leave the battery in the car. The electrolyte extended by this process will destroy the design of the AKB, which after such a "stress" cannot be restored.

Methods for recovering battery

We describe the most popular ways to resume performance, in which the repair of the car battery will give him an extra lifetime.

Battery protection

How to operate the battery

Pull the repair of the car battery and extend the service life of its service by performing simple rules:

at least once in the season it is necessary to control the density of the electrolyte;
during frosts above 20-25 C, it is necessary to bring the density to 1.35-1.4 g / ml;
to charge the battery, the current is used, less than 10 times from the numerical value of the tank;

if the car may be on an open parking during the frost from -25 s, it is desirable to hide it or pick up with me so that the frozen electrolyte does not bring the unit fail.

You will need

- Ready electrolyte
- distilled water
- Areometer
- Charger - for example "cedar" with automatic cycle mode, excluding recharge
- desulfating additive added to the electrolyte
- Pipette and small enema

Instruction

Most often displays incorrect operation. Fasting in traffic jams with inclusive headlamps, fan, the radio is depleted so much that the repeated start of the engine becomes impossible. Forgetfulness of drivers leaving for a long time enabarits - also lead to problems when you turn on the starter.
If it has decreased the capacity due to long-term discharge, sulfate plates - a long-term charging cycle will help to return it to life.

"Resuscitation" should be started from washing the battery with distilled water, thumbling the old electrolyte. Turn over and cut out all the garbage from it. And then on points:

Dilute in the electrolyte additive and pour it into the battery.

Connect the charger (bay stops do not spin!) And start a charging cycle in automatic mode.

The cycle is carried out until the voltage on the terminals reaches 13.8-14.2 volts.

Define the battery through the connected light bulb to voltage 10, 8 volts.

Start a charging and discharge cycle again, check the charge time and charging current. Alternating, determine the battery capacity. Upon reaching the nominal capacity, the restoration is finished.
These operations will help not only restore the car battery for further operation, but also teach it right to handle it later.

battery recovery

The reasons for the "death" of the battery are quite a lot, it can be the proofatration of plates, staying on a strong frost and much more. To "reanimate" the battery, you need to hold a number of actions that will help restore its performance.

You will need

- electrolyte;
- additive;
- distilled water;
- Charger.

Instruction

Leave for 48 hours, it is necessary that the electrolyte squeeze the excess air, and was well dissolved. If after that lacks the volume of the fluid, then the electrolyte is reduced to the recommended level. Usually it is worth a mark, to which the electrolyte must be poured.

Connect and enable the charging-discharge cycle. It is necessary to restore the battery capacity, it is impossible to charge immediately. After a peculiar "resuscitation", turn on the device into charging mode. Turn the current about 0.1 A, do not forget to monitor the voltage on the terminals. Be careful, it is impossible to allow heating or boiling electrolyte if this happens, reduce the current. Character until the current on the terminals does not reach 2.3 - 2.4 V per each of the sections.

Reduce twice charging current and leave the battery for another 2 hours. At this time, the density of the electrolyte and the current should remain unchanged. If after pumping the battery, the liquid is not enough, the electrolyte or ordinary distilled water.

Detach the battery using a conventional light bulb. Repeat the entire battery operation cycle first. It is necessary to sweat well. If discharge occurs very quickly, try adding a little more additive. This method Recovery of capacity and performance will help extend the life of the battery for many years.

If during charging the electrolyte hopelessly boils, you can safely throw the battery, it will not help him. This can be done with a frozen device, when even visually seen "swollen" sides.

The battery is an essential part of the car. It leads to a motion starter machine required to create rev. crankshaftwho will start the engine. Cars are equipped with a special charging relay that charges the battery during the engine operation. But the discharge of the battery can still occur for a number of reasons. During long-term operation of the battery, the electrolyte density drops and have to restore the battery.

You will need

- electrolyte with a density of 1.27-1.29;
- Charger;
- hydrometer;
- desulfating additive;
- distilled water.

Instruction

Remove battery corks. With the help of a carometer, measure the density. After that, drain the electrolyte from the battery. It is necessary to wash its sections with distilled water. Fill water into each throat and pour it through time. Repeat this process until the water becomes pure, without coal impurities and other garbage.

Fill a new electrolyte into the battery and add desulfating additive. Now, within two days, expect until the additive is dissolved in the electrolyte. During the same time, air is removed from the battery sections. After that, measure the density and, if necessary, add the electrolyte.

Connect the charger to the battery. Until you need to charge it completely. Exploct current in 0.1 amp. Discharge and charge it with a rectifier. This is necessary to ensure normal container. Do it until the voltage on the terminals reaches the value of 13.8 volts. Make sure that the electrolyte does not boil and not heated. This can lead to the destruction of the battery. Next, reduce current strength twice. If when charging for several hours, the voltage on the terminals does not change, stop charging.

Follow distilled water to the required density. After that, discharge the battery to 10.2 volts. After that, check the density, and charge again. Then add additives to the battery. After that, the battery can be used.

In the restored battery, as well as in the usual, never add the electrolyte. To bring to the required density, always use distilled water. Put the charging at lower currents.

If you have a non-working battery on your hands, you can try to restore it. Of course, in some cases, for example, if it is moving and when charging the electrolyte immediately boils, it is impossible to do it. With some other faults - the proofatration, partial destruction of coal plates - the operation of the battery can be restored.

You will need

- electrolyte;
- distilled water;
- Charger;
- a small range;
- Tester;
- Desulfative additive.

Instruction

Drain the electrolyte. Rinse with distilled water. Shake, turn over, shake all the garbage. Do it until the coal crumb stops up. If this does not occur, coal plates are destroyed. Stop washing - your nothing will help you. However, quite often this procedure helps to eliminate the closure of the plates.

The next step is to eliminate sediments of salts on the plates. Fill fresh electrolyte. Add. Leave the battery for two days. During this time, the additive will dissolve, air bubbles will rise to the surface. If necessary, fragile the electrolyte to the nominal volume. By the way, the additive can be dissolved in advance.

Remove the plugs, connect the charger. At this stage, "Training" is to be treated. Charging and discharge of the battery until its normal container is restored. Exhibits Charging Current Approximately 0.1 A. Ensure that the electrolyte does not heat up. If necessary, reduce charging current. Watch for tension on terminals. It should reach 2.3-2.4 V per battery section.

Reduce the current twice and continue charging. If within two hours the voltage on the terminals does not change, stop charging. Bring the density to the nominal. To do this, fray the electrolyte or distilled water.

Connect the bulb to the battery, the current of which is approximately equal to 0.5-1 A. Discharge the battery until the voltage value is obtained at 1.7 V terminals per section. If the container does not reach the nominal value, repeat the charging cycle and add a few more additives to the electrolyte. Close the plugs. The efficiency of your battery is restored. In the future, follow the general guidelines for the maintenance of AKB.

Most motorists rejoicing that thin poor battery served warranty period, get rid of it. Quick loss of tank, frequent recharging - they say how it seems to them, about the approaching batch of battery. Is it really, and is it possible to restore the car battery?

You will need

- Charger;
- ammonium solution of trilon B (ethylene diamine tetra acetic acid sodium);
- distilled water;
- Fresh electrolyte.

Instruction

In the practice of craftsmen, several ways to restore batteries are applied. Among them, for example: rejoice with low current and the treatment of the battery with a deep discharge. These methods require practically inconspicuous presence of a person and take a lot of time - up to several days.

The electrochemical method of restoring the car battery is carried out using a special charger. Batteries are restored when they charge them asymmetric current. This method allows you to restore the accumulated batteries of batteries, as well as carry out prophylactic processing of good battery.

The most radical I. fast way Recovery of the car battery - chemical. To carry out the chemical reduction of the container, you will need an ammonium solution of trilon B (ethylene diamine tetra acetic acid sodium), which contains 2% trillion b and 5% ammonia.

Before proceeding with chemical recovery, fully charge the battery. After that, carefully, in compliance with precautions, pour the entire electrolyte from it. Then rinse, preferably distilled water by 2-3 times.

In a thoroughly washed battery, pour the cooked ammonium solution of the trildon B. Leave the battery in such a state for desulfate, which will be accompanied by gas release and the formation of small splashes. After 40-60 minutes, gas formation will stop, which will indicate the completion of the process.

Drain the solution and rinse 2-3 times with distilled water with a battery. Fill the electrolyte of standard density into the banks and put it to the nominal container. Everything. Another 2-3 years restored battery will serve.

Batteries are:

Acidic;
Alkaline;
Gel.

The acidic battery is the most popular. The plastic box is divided into six sections, inside which there are beams filled with sulfuric acid with a dose of water, and lead plates, with a positive and negative charge. Plates are installed alternately - a positive / negative charge, there is a separator between them, eliminating random contact with each other. The battery performs the role of storage, and energy enters special terminals, turning into chemical reaction. With the primary launch of the car, the battery loses the energy charge, which is replenished after a while. In chargeable condition, sulfuric acid is in electrolyte on positive electrodes, and in the discharged - in the form of sulfate on the negative electrodes.

Causes and elimination of the discharge of AKB

The external cause of the malfunction is easy to detect when inspection: the connection to the onboard network is violated due to the oxidation of the terminals or due to the damage to the plastic case (crack or mechanical barrels). With serious faults, it is possible to repair and use the battery only if it refers to the serviced battery. Oxide on terminals is easily removed, and cracks to sink, pre-drained the entire electrolyte. Additional flushing of the battery can be delayed for a month, since after cream electrolyte, distillates are poured into it, washed, and put to charge. Faster chemical flushing is carried out with the help of ammonia mortar and "Trilon B". The electrolyte is drained before the procedure from the discharged battery, and the ammonia solution added after pre-washing with distillate will boil. After boiling, the solution is drained, the box is washed, charge on a new one.

Worse, if the plates themselves are damaged: sulfate - reduction of power, overheating, electrolyte boiling or squeezing with the closure of lead plates. Delete malfunction in such cases is almost impossible. It is the incorrect maintenance of the AKB (a long charge, or, on the contrary, insufficient) leads to irreversible violations.

To remove a whitish oxidation flask, use the rag, and then carefully clean the contacts using sandpaper.

The second step is to complete the battery charging with the subsequent discharge (cycle charge-discharge with the capacity of 60 hour battery at a voltage of no more than 3,6A). If everything is done correctly, the AKB density should be 1.27. After complete charging, an automotive incandescent lamp is used for the control discharge. The lamp power must correspond to the battery capacity. With proper discharge, the voltage in the terminals should be dropped to 10.2 V.. Then again put the battery for the charge, this time the final one.

A more sparing method - the supply of battery with energy with minimal current charges. To do this, you must have a special generator.

If the battery swelled in the cold, then the restoration is not subject to, only full replacement. So that problems with the car did not occur, once every six months spend a full charge of the battery.
