Is it possible to wash the battery with simple water. Correct car battery care

03.02.2021

How to restore the car battery? Such a question arises not only from newbies, but also from experienced drivers. After all, on how well it is functioning, the performance of vehicles depends, the launch speed.

Before recovering the car battery with your own hands, the causes of the breakage are studied.

The container is lost for several reasons:

  • Lead sulphate formation. Such a malfunction arises constantly. Determine the damage of batteries can be charged.
  • The failure of the bank, which is included in the power supply. It occurs due to short circuit, which occurs between lead plates. With subsequent use, the electrolytic composition begins to boil, the container falls.
  • Destruction of lead plates. The remains fall into the electrolytic composition, change its properties. In these cases, the rechargeable battery is not restored.
  • Freezing of electrolytic composition. Some batteries are filled with a substance that is characterized by increased density. At a negative temperature, the composition freezes, the housing is destroyed. It is impossible to reanimate the battery with your own hands.

Based on the foregoing, it can be concluded that the battery malfunction occurs due to improper operation of the power supply.

Effective ways to restore the automotive battery

Knowing how to restore the car battery on your own, you can get rid of many problems.

Desulfation of lead plates

In lead-acid power sources, crystals are formed when absorbing energy, which include lead sulfate. With constant use, sulfation practically does not affect the performance of the battery. Another dependence is traced:

  • A small discharge leads to the appearance of small crystals. They quickly dissolve in the electrolytic composition.
  • After a deep discharge, large sizes sulfates are formed. They are not destroyed.

Purification of lead plates is performed:

1. physical way

The auto accumulator at home is dismantled. After that, the plates are withdrawn, cleaned. To simplify the seizure process in the lid, holes are formed. For these purposes, a soldering iron is used, with which it is easier to carry out work.

Purified hand plates are washed. For this use distilled water. It is necessary for washing the inner part of the can. After all, the flushing of the battery contributes to the restoration of performance.

After that, the plates are placed inversely, poured with electrolytic composition. Rechargeable battery charge.

It is difficult to implement such a way, since the integrity of the plates is easy to disrupt.

2. Chemical method

A solution is used for cleaning, which introduced active substances. Restoration of AKB with a chemical method requires 1-3 hours. But preparing the substance is required before implementation.

Power sources are restored:

  • Full battery charging.
  • Drain of electrolytic composition.
  • Cleaning, flushing car battery. For these purposes, distilled water is used.
  • The solution is poured for 1-2 hours. This time is enough, so that sulfates were dissolved. Gases are distinguished during the process.
  • Re-wash the battery is important. After all, from the inner part of the case it is necessary to withdraw the residues of sulfate.
  • Pouring electrolytic composition with the required indicators.
  • Re-charging power source.

When chemical cleaning is the likelihood of lead in banks, between the plates. This often provokes KZ.

Resuscitation with the charger

How to restore the old battery yourself? You can use charger. But this method takes a lot of time, forces. After all, the alternation of the discharge-charge of the battery is required. This leads to a gradual dissolution of lead sulphates.

The level of electrolytic composition is checked before implementation. Before charging, electrolyte or distilled water is performed if necessary.

Recovery is performed by a conventional or pulsed charge. Choosing an option, it is necessary to take into account the state of the battery unit, the duration of its operation.

Pulse charging

To resuscate the rechargeable source, the memory is used, which is equipped with such functions:

  • Desulfation.
  • Pulse charge.

Such an aggregate is summarized to the car battery that you are trying to revive. Wires first connected to the source. After that, burst into the network.

The charge is supplied for 9-10 minutes on a small current. After that, the appropriate load is supplied. This is enough for the power source completely discharged.

Installation and other time intervals are allowed.

The pulse charge is applied provided that the battery state is normal. After all, the cost of such a device is quite high.

Application of standard zoom

Resuscitation of the battery is possible and using a standard memory. Before proceeding with the restoration, you need to clean the unit, remove the residues of the oxide, lower the electrolytic composition.

  1. Charging the power source on small currents for 9-10 hours. The current level decreases if the unit is overly heated, the electrolytic composition boils. If everything is performed correctly, the voltage increases slightly.
  2. Rechargeable power supply is disconnected from charging. At rest is left for 12-24 hours.
  3. Repeated to zoom. The current rises to 2,5A by 6-8 hours. This contributes to an increase in the level of density of the electrolytic composition, an increase in voltage.
  4. The discharge of the power supply to 8-9 V. To do this, the lamp is supplied to the device.

Activities are repeated until the optimal density is established, the voltage of 12-12.5 V.

Battery restoring in the usual charge takes more time. But with it, even old power supplies reanimate.

KZ "Banks" of the rechargeable battery

Such a breakdown leads to irreversible consequences, if not take timely measures. After all, the performance of intact "cans" is gradually deteriorating, as a huge current comes on them.

To restore the auto accumulator, follow-up activities:

  • Definition of banks that failed. In the process of charging, the non-working element boils or does not function at all.
  • The electrolytic composition is merged from the damaged bank. Such actions are performed in rubber gloves. After all, when burning with electrolyte, a burn is formed.
  • The holes are prepared through which lead plates are withdrawn. They are washed using distilled water.
  • Determination of the cause of the CW. In old batteries, the reason is a precipitate that focuses on the bottom of the jar. Therefore, you need to know how to wash the jar.
  • In the purified jar placed the plates of lead, the electrolyte is poured.
  • The formed hole is neatly searched.

With careful execution of all processes, the power supply is restored.

Resuscitation of a non-servant battery

Other power supplies can be restored. After all, it is prohibited to create a hole in the lid, as this negatively affects the system of the gas feed.

The process of resuscitation of non-maintained auto accumulators includes:

  • Determining the level of electrolytic composition. For this, the housing is shouted with a lighting device.
  • With a deficiency in the housing, the hole is prepared. It should be slightly higher than the level of electrolytic composition. The magnitude of the opening is 2-4 mm.
  • Pouring distilled water. It is carried out using a syringe.
  • You can close the hole using soldering.

The device capacity is restored by discharging and charging. These processes are performed cyclically.

Restoration of the helium power supply

Resuscitation of gel type power supplies are more simple. After all, there is no need to prepare holes. Recovery includes such actions:

  • Dismantling upper cover.
  • Neat seizure of rubber caps, which are located under the lid.
  • Translucent cans that are included in the composition. Banks are considered workable if the insides are preserved. When detecting ducts or other contaminants, the resuscitation of power sources is not conducted.
  • Each plot distilled water (1-2 cubes). After that, the source is seal. This procedure is accurately carried out in order to ensure tightness.

Restoration of helium battery is not carried out in such cases:

  • Complete destruction of lead plates. This may be the result of long-term operation of power supplies at elevated temperature.
  • Swimming power source.

Resuscitation and distilled water

It is possible to revive the car battery with distilled water. It takes 45-60 minutes to implement this method.

If the rechargeable battery is completely completely, then it is charged before resuscitation. After that, the electrolytic composition merges. For this, twist the plugs that are focused on the lid.

The housing and elements are washed with distilled water. After that, the special solution is poured, with the help of which desulfation is performed.

The desulfation process is accompanied by gas release. Therefore, placing the recovery source is better in the room in which the ventilation system works.

Distilled water is used for cleaning. The flushing procedure is performed 2-3 times. Only after that the electrolytic composition is poured inside, which has the required density.

The reanimized power source is connected to the charger and network.

This restoration method is easy to implement. Therefore, they can enjoy newcomers, experienced motorists. But the duration of operation of the recovered power supply is difficult to install. It all depends on:

  • Timely maintenance.
  • Compliance with the terms of use.
  • Periodicity of vehicles.

For example, the frequent operation of the auto accumulator in a discharged form leads to the fact that it is impossible to restore it.

The process of restoring the automotive power supply includes many aspects, rules. And on how accurately they will be implemented, depends, whether you can revive the aggregate. Therefore, all stages must be performed in accordance with the recommendations of specialists.

4 ways to restore the car battery

Batteries are a stable source of constant voltage, they are indispensable in separate design and instruments. But of course there are no eternal things on Earth and with batteries, it takes time and they are no longer suitable for use what to do? Throw away and buy new? You can of course, but it is better to try to repair them. On the market you can find a sea of \u200b\u200bbatteries of different types of containers and voltage. Basically use acid alkaline and lithium batteries. Today we will talk about the methods of repairing such types of batteries, like lead. Acid batteries - more often they are called lead helium. Two lead plates are immersed in sulfuric acid, one plate is a positive pole, the other is negative. Such batteries are most often used in automotive equipment and in pocket lanterns. They have a relatively low service life. They can be repaired (restore) in several ways.

The first method of repeated charging with a small value of current with small temporal interruptions between charging. By the end of the first and subsequent charges, the voltage on the battery is gradually rising, and it ceases to take charge. During the break, the electrode potentials on the surface and in the depth of the mass of the plates are aligned, with a more dense electrolyte from the pores of the plates flowing into an interelectrode space and reduces the voltage on the battery during temporary breaks. During the cyclic charge, as the battery kit is set, the electrolyte density begins rises. When the density becomes normal, and the voltage on the same section will reach 2.5-2.7 volts (the nominal of each 2 volt can) is terminated. Repeat this cycle 5-8 times. Charging current of ten times less battery capacity, let's say the battery has a capacity of 1000 mA / hour, then the charge current should be from 80 to 100 ml.

The second way to restore acid batteries is the replacement of the electrolyte. We drain the electrolyte from the battery and rinse the battery with hot water several times. Next, we take 3 teaspoons of soda and dilute in 100 ml of water. Boil water and immediately pour boiling water into the battery, we are waiting for 20 minutes and drain. This process is repeated several times. Then we rinse with hot water battery 3 times. This restoration method is very convenient to use for automotive batteries. At the last stage of the work, we pour a new electrolyte and charge the battery 24 hours, the repaired battery is charged once a day for 10 days, the charge lasts 6 hours, the parameters of the charger - 14-16 volts, charge current 10 amp (no more).

The third method is a reverse charge. To do this, you need a powerful voltage source (welding machine for example), the voltage of the charger 20 volts, and the strength of the current is 80 amps and more, open the jacks of cans and charge them only back - plus the power source is attached to a minus battery, and minus power supply to the plus battery. The battery will boil, but do not pay attention, charge within 30 minutes further drain the electrolyte, rinse with hot water and pour a new electrolyte. We take an ordinary charger with a current of 10-15 amps and charge the repaired battery 24 hours, just do not confuse polarity since the factory plus pole will already have a minus, and we will talk about the repair and restoration of alkaline and lithium batteries in the next article, stay with We are Arthur Kasyan (Aka).

Fourth way Differs high efficiency and efficiency (the battery is restored in less than an hour). The discharged battery is preloaded. The electrolyte is drained from the charged battery and washed 2-3 times with water. A flush battery is poured an ammonium solution of trilon B (ethylenediaminetetrauxuscase sodium) containing 2 weight percentage of trilone b and 5 percent of ammonia. Time desulfation with a solution - 40-60 minutes. The desulfation process is accompanied by the release of gas and the occurrence on the surface of the solution of small splashes. Termination of gas division indicates the completion of the process. With severe sulfate, the solution to the solution should be repeated. After processing, the battery is washed at least 2-3 times with distilled water, then filled with normal density electrolyte. The flooded battery is charged with a charging current to the rated tank according to the guidelines. On the issue of preparing the solution, it is necessary to apply to enterprises with chemical laboratories. The solution is stored in a darkened place in a vessel with a hermetic lid to avoid evaporation of ammonia. http://www.handiman.ru/

battery recovery

Probably, every car enthusiast at least once came across a situation where 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, at home, you can not only restore the battery, but also to extend the life of its operation for a few more years.

How batteries are arranged, the principle of work

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 of the capacity is reached, the AKB will turn into a source of energy with a voltage in 12 V.

Every time the car 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 to the limit, but how to reanimate the battery, car enthusiast, 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

So, a typical battery is lead plates in sulfuric acid. This metal is easily destroyed by the impact of weak acids, for example, acetic. But the sulfur for him is not at all dangerous, even if it is very concentrated or heated. A film that is formed as a result of a sulfuric acid reaction and lead protects the metal from the destruction.

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.

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, lead is doped with calcium. This allows you to reduce virtually minimizing water boiling and reduce self-discharge. However, if the battery was discharged quite strongly, the electrodes are covered to charge this acb completely will not succeed. Due to the fact that 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.

Sowing coal plates

It is also a fairly common cause, which fails. Diagnosis to deliver easily - sulfuric acid will darken. In this case, there is a risk of battery death - unfortunately, such a task, how to reanimate the car battery, in this case is not solved.

Lead acb in the course of evolution changed many times and upgraded.

However, the principle of operation remained all the same. On the plates applied paste oxides of lead. This part or namaze is held on the electrodes due to the coupling properties and the design of the plates. It crepts as a result of vibrations, sulfate, temperature fluctuations. The crying process is quite natural. This speaks about the aging of the battery. If you treat the battery neatly, the service life will increase significantly.

How to reanimate car battery

For reasons, everything is clear. In warranty coupons for cars in this case, the driver will only find a recommendation for replacing the battery. But there are options for restoring the power supply.

How to raise the container and density

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.

It is possible to stop the procedure if recovered and the voltage level is in the limits permissible for a particular 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 the cavity is poured and the trillion b 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 with a 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.

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.

Circuit repair: Method number 2

To eliminate the closure, the problem zone is burned with large currents. To do this, it is enough to connect the battery to the welding machine with the current should be from 100 A. The chain is closed only for a couple of seconds.

On the maintenance-free AKB

Manufacturers have made these batteries so that they are simply changed.

On how to reanimate the maintenance-free battery, they do not write in the instructions. But there is still a way.

The first thing is poured the electrolyte, and replace it with distilled water. Next, the battery is charged on a constant voltage in 14 V. in a few hours it is necessary to listen to what happens inside the battery. The process must be accompanied by the formation of gases. With intensive selection, the current is reduced.

In two weeks, the battery will turn water into the electrolyte, and lead sulfate is converted into sulfuric acid.

After two weeks, the contents merge and water poured again, and this process is repeated again. When the desulfation is completely over, you can pour a normal electrolyte and charge the battery with standard parameters.

How to reanimate the battery, the modern manufacturer does not tell. All these methods are used by motorists themselves, at their own risk. The main thing is to accurately comply with these recommendations, and then there is a chance that the battery will revive and will delight your owner for many years.

So, we found out how to reanimate the car's maintenanceable battery.

The flushing of the battery refers to one of the non-core ways to restore it.

But as a rule, car services in this type of work do not do, as it is believed that this does not lead to tangible results.

Usually, batteries are washed and the electrolyte of car owners at home, as they try to extend the battery life and save on it.

When you need to rinse the battery, signs

Signs that will indicate not only on the need for washing the battery, but also to other problems:

  • Fast charge and battery discharge;
  • Unnatural (brown) electrolyte color;
  • The battery is "dead" - does not give out voltages.
  • The causes of the above features are:

  • As a result of deep discharge and sulfate, the plates decreased the capacity of the battery;
  • The shuddy sludge not only changed the color of the fluid, but also closed the plates among himself.
  • It cannot be said that after washing the battery will restore its previous characteristics, most likely not, but for a while it can extend its service life.

    Also, the dark color of the fluid indicates that the active substance from the plates is already beginning to crumble and the plates themselves have become thinner and you can not restore their thickness.

    Therefore, even after washing the battery and the complete replacement of the electrolyte, it is not worth talking about a long period of battery life.

    And yet, it should be understood that modern batteries in a plastic case with a common lid, especially those who are maintained, when closing the plates immediately change to new ones, since their disassembly, replacing the plates and the subsequent assembly with sealing is a clapboard.

    To check on the closedness, the load plug is used if the battery does not hold the load (the voltage is constantly falling and lowered below 10 volts), it means that at least one bank is closed.

    Stroke work

    For flushing need:

  • Rubber pear or a special device for draining (not suitable for all cases);
  • Capacity where everything will merge, preferably glass or metal;
  • Load plug;
  • Rubber gloves, glasses, clothing made of dense material;
  • Hydrometer.
  • Fully discharge the battery available for you. If banks are not closed (i.e. there is no sediment at the bottom), then a special design or rubber pear can be used to remove old electrolytes.

    As for the construction, the moment is controversial, as specialists do not recommend tilting the battery greater than 45 degrees, since the shredded elements of the plates can close the latter.

    But our people do not stop, especially many manage to drain the electrolyte, for flushing, drill holes in the housing.

    At the final stage, pour distilled water again and let it stand for 3-4 hours.

    If you understand that there is a precipitate (the bank is closed), then you should not turn the battery, as it is only aggravated by the situation.

    Here, at the first stage, the liquid of rubber pear is extracted, then disassembly of the battery, cleaning it from sediment and old electrolyte, assembly and sealing. Is it worth doing this, everyone solves himself for himself.

    Do not make mistakes with density

    Before pouring a new electrolyte after washing the battery, analyze which situation has led you to these actions, because a mixture of sulfuric acid and distilled water is sold with different density - from 1.2 to 1.28 g / cm3. Which one to pour?

    For example, in winter the battery was discharged, was on the street and in it, as a result of the density drop, the electrolyte frozen. Of course, in this situation the car will not start.

    At this point, the battery is in a state of deep sulfation of minus plates.

    What makes the driver in this situation? That's right, it heats the relatively warm and measured the density of the liquid, which is usually low 1.15 g / cm3. This brings to the erroneous idea to replace the liquid, the bay is the same, but with greater density. And here, as a rule, an error is allowed.

    An important point is not taken into account - the density of the old electrolyte. As a rule, in winter, with a fully charged battery, it is equal to 1.27 g / cm3. The fusion was a liquid with a density of 1.15 g / cm3. And where are the remaining 0.12 g / cm3? And they are on minus plates in the form of a sulfatized plaque.

    A person remembers the figure of 1.27 g / cm3 and, accordingly, it buys the electrolyte with the same density.

    After the new liquid was filled into the battery, the latter, usually immediately charged. And what happens? As a result of charging and desulfation, the remaining 0.12 g / cm3 are somewhat from the plates and are added to the total density of 1.27 g / cm3, in the amount, 1.39 g / cm3 is obtained, and this is a digit approximate to the correction electrolyte density.

    Therefore, in the case provided for example, it would be necessary to simply hold the CTC of the battery.

    Or, if the charger allows, turn on the cyclic mode of short charge and discharge on it to lead the fluid density to the real one. You also need to connect to the battery any consumer of electricity, for example, lamp headlights.

    A large density of sulfuric acid negatively affects the state of the plates and in this aggressive environment they begin to quickly crumble.

    Therefore, after washing the battery, so as not to get into the situation described above (we have an acb space), filled with a density of 1.20 g / cm3 to start the electrolyte.

    An electrolyte is agreed to increase the density, and distilled water. Clean sulfuric acid is not in any case.

    The performance of the automotive battery is limited. When he fails, many just buy a new one. But almost every battery can be restored so that it still serves.

    1 Battery Malfunctions - Symptoms of Disease

    In the closed plastic container there are positive and negative plates. Inside the solution of hydrochloric acid is poured, referred to as an electrolyte, forming a galvanic pair with lead plates. The terminals serves a current from a charger or generator. When it is accumulated enough, the car battery becomes the source of electricity. It is spent on the engine start, the operation of the instruments and lighting.

    The generator fills the loss of energy, but over time, for different reasons, the accumulated stock is missing for normal engine start. With the correct operation, there is a temporary factor: the plates are aging. Under certain conditions, you can restore the battery, breathe a new life into it. There are several resuscitation methods. To choose the most suitable, we first determine the reason for the inoperability.

    The most common cause of dying is sulfate lead electrodes. The discharge is accompanied by the formation of plates on the plates. If you do not allow critical discharges, then when charging the crystals dissolve. But the causes of sulfate not only in deep discharges. It is also caused by other circumstances: permanent underwear, long storage in the discharged state.

    Sulfate is quite easy to determine visually. We unscrew the plugs and inspect the plates. Light white-brown flare testifies to the presence of a process. Other features, including non-maintained acidic batteries:

    • when charging, begins to boil very quickly;
    • a fully charged battery does not twist the motor, sits in a few minutes from a regular light bulb;
    • white bloom on the housing.

    The second common fault is destroyed plates, their sprinkle. It is easily determined by black battery-colored acid. If there have been a lot of grilles, liven up such a voltage source is unlikely to succeed.

    Neighboring plates can be closed. This occurs as a result of their deformation or sprinkling and formed at the bottom of the sludge. The closure occurs, as a rule, in one of the sections. A clear sign of KZ - electrolyte when charging in that jar does not boil or boils later, but the voltage indicator does not grow or grow very weakly.

    Finally, the acid electrolyte can freeze. This happens when storing a strongly discharged battery in the cold. The ability to restore depends on the degree of damage to frost. If the ice-generated ice ripped the plastic case, then the plate, probably, was quenched, and they were closed, after defrosting, they will begin to crumble. If the housing is whole, wech the heat, and you can try to restore.

    Any repairs start with cleaning. We remove the dirt from the surface, rinse with soda solution to neutralize the electrolyte, which is almost always on the lid. Cleans the terminals from the plaque with a small sandpaper. By the way, try how a car battery works with cleaned terminals. Often their oxidized surface does not allow to charge normally and to give electricity.

    2 Simple desulfation - we use the usual charger

    If the battery is overwhelmed, and the plates did not appear (electrolyte clean), it is possible to restore it using a simple charger. We need to break the flare on the plates. In serious literature, a pulse charging is recommended, alternation with discharging, strict hold of modes. Manually do it quite difficult, and special chargers are expensive.

    In practice, everything can be done much easier. We use the simplest memory with a small alteration. We throw smoothing filters at the output of the lowering transformer. Instead, we establish a diode rectifier. Each of the four diodes is designed for current 10 A.

    It will take a carometer to control the density of the electrolyte. We check it in all banks, recording the indicators. If there are 1.20 and lower, it's time to act. We look after the level: if there is an insufficient, pour the electrolyte standard density so that it closes the plates by 1 cm. We connect the charger, set the current 10% of the tank. If we have a battery of 60 Ah, then 6 A, you can less: 3-5 A.

    In a simple memory, without fixing the parameters, the ammeter will first show some increase in current, then it will decrease, and the arrow is zoked in a certain position. From time to time, we watch the process in order not to miss the boiling start. After it, the current is reduced to 2 A, we continue to charge until it starts boiled again, and another 2 hours after that.

    After graduation, the density is measured: it grows slightly. Leave the battery disconnected from the charger at the same time that it was charged. Again, we measure - we observe a small increase in density. If it has not come to normal, repeat the cycle. One day is left, usually the recovery occurs after 3-4, sometimes you have to repeat 5-6 times.

    Never add an acid to an accumulated accumulator: it will only speed up the process and can lead to the death of the aggregate.

    3 Second Method - Cycled Charge-discharge

    There are automatic charge devices like "cedar" and similar. In the process of charging, they are independently disconnected at the right time. Pre-conduct a complete charge to the highest possible level. Then 3-5 days turn on in the workout mode. In parallel, we cling the light bulb from the rotary lamp, press the corresponding button. The process is happening: about a minute is charging, then 10 seconds discharge. After training, I charge finally.

    Several schemes of homemade devices have been developed, which are similar to the factory, give a short pulse charge current and spend a small discharge in the intervals. The figure shows a diagram for which it is not difficult to create such a device if there is knowledge of radio engineering.

    We connect it to the terminals and watch the LEDs. Green glow speaks of readiness for operation, and yellow and red - about the need for desulfation. We carry it out like this:

    • we connect the device for a while until it is completely discharged (the D1 LED goes out);
    • connect the memory and charge;
    • we repeat the desulfate until green diodes D7, D8 appear.

    Perhaps the process charge-discharge will have to repeat repeatedly. In particularly launched cases goes week and more. The feature of the device is that it consumes only 20 mA, it can be connected to the onboard network. It will constantly maintain the right state of the battery without affecting the operation of the generator.

    If there is no pulse memory, but we cannot do it yourself, we try to use manual mode. We take a simple charger with fixed settings. I exhibit 14 V and 0.8 A, we leave for 8-10 hours. The voltmeter will show the increased parameters. Be sure to leave for a day to settle and charge again, but the current 2 A. Voltage with density will increase a bit.

    Run the process of desulfation. We connect a light bulb. For 6-8 hours, we see the voltage drop to 9 V, we no longer admit - this is what we need. We will have to control the voltmeter. We repeat the cycles:

    • night - I charge 0.8 A current;
    • day costs;
    • again the night - Charging 2 A.

    Depending on the degree of launching, the process takes up to two weeks. A fully discharged battery is restored by 80%, which is enough to start the engine.

    4 Change the electrolyte - return to the life of short-circuited batteries

    If the liquid in banks has gained incomprehensible color: turbid, black, it will have to be replaced. This happens in very old, long-used batteries and short-circuit. In general, if the CW occurred due to lattice warp, it is possible to reanimate only by physical intervention.

    On old batteries it was done simply: each bank was separate. Short-accumulated opened and installed new plates. Now all individual elements are enclosed in the common case, and such intervention is difficult, but maybe. On how to do it, tell me further, and now, how to change the electrolyte.

    A short circuit is determined by black color, which has already been mentioned, and in charge. All banks begin to highlight the gas, and the shortly accumulated this does not happen. Further drain the electrolyte, pulling the pear. It is possible from one container, and better from all - the fill with fresh electrolyte does not prevent. Finding distilled water further, we slightly we swing the housing and carefully drain. Do not turn over so that the sludge is not stuck between the plates. We repeat until the water becomes clean.

    In a bank with KZ, we resort to a more radical way. Serve a small hole 4-5 mm in the bottom of the housing, we drain the electrolyte and rinse with distilled water. All the sludge goes away, nothing remains. Hole close the plastic, applying a soldering iron. If the plates are not fed, then it will be enough to change the electrolyte.

    The further process is happening like this:

    1. Pour the electrolyte with a density of 1.28. It is possible in two days to dissolve in it a pre-special additive for desulfation. Let's give to the day to come out.
    2. I charge 0.1 A current to the full density restoration, watching that there is no rapid boiling and severe body heating. If necessary, turn off, let it cool. We charge to 14-15 V.
    3. We look at the testimony of the area, reducing the current and leave for 2 hours. If during this time the density did not change, stop charging.
    4. We discharge a current of 0.5 a to 10 volts. If the indicator fell to this mark earlier than in 8 hours., Cycle repeat. If not - just charge to the nominal indicators.

    And now about replacing the plates in an unclear battery with your own hands. Around it on top of cut plastic. Jumpers going to neighboring banks, disconnect in any way: we disappear or cut. We take out the package and rinse well in water to wash off the residues of the acid. Now we are looking for where it closes. We look at the plates and dielectric. Task: detect a particle that connects two plates.

    Found - well, we remove it. First you should rinse, removing the whole thing, the package is installed in place. We restore the jumpers, glue the cover using glue, epoxy resin or melting with a soldering iron. Pour electrolyte and charge. If the plates are fused, you can use them from another old battery, selecting the least damaged package.

    All work should be carried out in gloves and indoors with sufficient ventilation, and better in air: sulfuric acid and gases can cause harm to health.

    5 chatter - the last chance in hopeless situation

    If a strong voltage drop occurred in one of six tanks, when charging the poles change its value. A chain reaction is provoked, which leads to the same consequences in neighboring banks. The causes of the occurrence of such a situation are:

    • excessive sulfate, non-recovery;
    • incorrect connection of the battery for charging, which does not have protection against cords;
    • dirt on the housing causing a constant self-discharge;
    • the discharge is not controlled, a strong discharge occurred repeatedly;
    • errors in the operation of the generator and other power supply and consumption devices.

    The method of cakes is considered to be barbaric, but in other ways resuscitation is impossible. If there is a failure, there is nothing to regret, still the battery had one way - disposal.

    To begin with, select the electrolyte from all cans with a carometer and look at the indicators. Reveal fully workers, patients and dead. Dead, as a rule, a little: one or two. Restore the container, by and large, follows only from them. But the solid body does not provide disassembly. You can use the technique described above to get to the defective banks.

    We will tell you how to reassure all the containers at home, without resorting to the disassembly:

    1. First we discharge the old battery to zero, connecting some load, such as a car light bulb. We measure the voltage: if something remains, closing the terminals.
    2. In the rupture of the minor terminal of the charger, we include ballast resistance. Summer resistor 50 com. It will protect the plates from short circuit.
    3. Connect the wires from the memory in reverse polarity. Plus - to "minus" battery, minus - to "plus".
    4. We charge the current consisting of 10% of the container. The charge is gaining enough quickly, but the body is very heated.
    5. Lower the current to 2 A and continue to charge. Let me get bored with a low current 2 hours and turn off.

    Checking the density: in normal containers it drops, in the killed rises. Further we carry out a strong discharge, closed the terminals. Connect to the charger, observing the correct polarity. We charge according to the above scheme. To restore it is recommended to make a reversive twice.

    You should not resort to ignition when there are such signs of malfunction:

    • in banks black electrolyte;
    • short circuit;
    • insufficient density level.

    First, we use repair methods for a particular case, and if it does not help - we use the ransom.
