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.

Low current recovery
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.
Device 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.
Revealing traffic jams battery As a result of the use of partial discharge techniques contributes to an increase in electrolyte density. 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.
Bay 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. 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 the use of special memory. In detail with the recommendations on this issue can be found in.
Any experienced motorist knows that if there are difficulties associated with the battery in the car, it is impossible to slow down with the correction of the situation. The fact is that the consequences of such a delay can be the most unpredictable. Up to the sad outcome, because if the battery is not working, in the most responsible moment, the engine can simply not get started. Thus, an extremely dangerous situation will be provoked in which not only the car owner itself and its car can suffer, but also other road users.
Therefore, for security purposes, it is necessary to eliminate the battery malfunction or replace this unit at the first opportunity. One of the most popular and fairly effective methods for recovering the battery is washing of this unit. Rinse the battery with your own hands is not so difficult - it is only a novice motorist.
When must be done flushing the battery?
First of all, you must make sure that the battery washing is really necessary. Experts recommend flush the battery in the following situations:
The electrolyte in the battery changed its color (from pink up to brownish).
The battery is very quickly charged to one hundred percent and also quickly discharged in full zero. Perhaps the reasons for this are the resulting sulfure (salt deposition). The self-discharge of the battery can also occur due to excessive contamination of the surface of the unit and, accordingly, the disorders of the insulation resistance of the cover, as a result of which the current leak appears (self-discharge).
Upon completion of the voltage check on the terminals of the battery, the device is too low or zero. This indicates that too large the amount of sludge was formed, which falls on the bottom of the active layer of plates. As a result, the short circuit of these very battery plates is overlapped.
Of course, the flushing of the battery will not be able to fully solve all the above problems, however, with a lack of money or time, this method can be used to independently extend the service life of this unit. Before you try to rinse your battery yourself, check out the instructions below.
Step-by-step instruction:
1. Fully discharge the battery.
2. With the help of rubber pear, pull out the electrolyte and drain it into the glass container pre-prepared for this. Subsequently, this electrolyte must be disposed of.
3. Instead of the fused electrolyte, pour clean distilled water. Repeat this process until pure water remains in the bank.
4. Give the battery to stand for about three hours. Then pull the water using a rubber pear all the tight.
5. Follow the electrolyte in banks, while bringing its density to 1.2.
6. Battery Connect to the charger. Charge the battery until the battery voltage is normal. Bring the electrolyte density to normal indicators (depends on the temperature "overboard").
june 25, 2017
Every year new models of batteries (AKB) with improved technical characteristics appear on the market. They have a high reserve capacity, work perfectly at low temperatures, are not afraid of deep discharges, easily give big currents and perfectly take a charge. But one remains unchanged - protruding the terminals of batteries are quite vulnerable and require special attention. Our material will tell how to get rid of the oxidation of contacts and battery terminals and ensure its impeccable work.
Why the battery terminals are oxidized
With the problem of the oxidized battery terminals, every vehicle is faced. It becomes particularly relevant in the off-season when high humidity and frequent temperature change can significantly speed up this unwanted process.
In most cases, the oxidation of the battery terminals is due to the elevation of the electrolyte vapors, the electrolyte leaks on the contacts or malfunctions of the electrical equipment of the car.
ON A NOTE
It should be remembered that even a new battery can evaporate a little acid.
However, having noticed on the surface of the battery of the battery white bloom, first of all it is necessary to deal with the causes of its occurrence. After that, you need to take all necessary measures to eliminate it and prevent re-appearance.
Possible effects of the oxidation of contacts and battery terminals
Many car owners do not consider the appearance of a white fly on the terminals of the battery with a serious problem, but it can deliver a lot of trouble. Often drivers, facing the problem of engine launch, do not even suspect that it may be in the oxidized terminals. After all, the terminals covered with a milestone significantly reduce the efficiency of the battery. And in cases where oxidative processes are so intensively, that the white flare almost completely covers the terminals, the battery may not cope with its task - and you will not even make your car.
To avoid unexpected surprises, it is necessary to regularly examine the battery, follow its condition, to make prevention and, of course, take measures at the very first signs of failures in its work.
How to see and eliminate the problem of oxidation of contacts and terminals
It is possible to determine what the problem is precisely in the oxidation of contacts, it is possible according to the following features:
- You include ignition, but the starter "grabs" is not the first time or too hard turns the crankshaft, as if the battery is greatly discharged. The reason may be in the oxidation of the terminals, especially if your acb is quite new or you have recently poured the electrolyte and charged the battery.
- The light of headlights and overall lights has become much more dim. Look for the cause not only in a weak charge - perhaps this is a signal that contacts were oxidized on the battery.
In any case, in this situation it is necessary to take timely measures to prevent serious problems with the electrical equipment of the car. And there are only two ways to solve this problem:
Replacement of Account
This is the easiest and fastest solution to solve the problem, but it is not always necessary to go to extreme measures. Of course, there are situations where the replacement of the battery is the only correct solution (for example, when the electrode fastening). However, in some cases, radical measures can be avoided.
Removal of white plaque with terminals and their insulation
In this case, special compositions protect them from corrosion and oxidation on the battery terminals are applied, which increases efficiency and extends the service life of the AKB. This method will allow not only to eliminate the problem of oxidized contacts, but also for a long time to prevent its re-occurrence. For isolate the contacts of the battery with the help of modern products is not at all difficult, and we will tell how to do it right.
Clean the contacts and terminals of the battery
To clear the battery terminals as quickly as possible, efficiently and safely, it is necessary to comply with the correct sequence of actions:
- As with any work with the electrical equipment of the car, it is mandatory to drag the engine.
- With the help of a suitable key to loosen the negative terminal and remove it from the battery. Only after that we liberate and remove the "plus".
- Carefully examine the battery to detect possible defects in a timely manner. If you have serious damage, the battery must be replaced.
- We check the battery terminals and leading wires to them for physical wear.
- Before starting the fight against a flaw, put on rubber gloves that protect your hands from the effects of aggressive substances.
- If you have found a thick layer of white plaque on the terminals, its main part must be removed by mechanical way. This can be done with shallow emery paper or a special metal brush. In the extreme case, you can use a knife or other sharp object. The most carefully need to clean the place of contact of the electrode and the terminals, paying particular attention to the inner surface of the latter. It is necessary to act at the same time, so as not to damage the protective sheath of the wire.
- Then (or immediately - if a slight is a bit), dissolve the tablespoon of soda in a glass of water. Apply the agent to the old toothbrush, then read the terminals well to remove the oxidation products.
- Rinse the cleaned places with distilled or conventional cold water, then wipe the terminals of dry.
ATTENTION!
It is strictly not recommended to clean the contacts with gasoline. Such tips can often be found on the Internet or hear from familiar motorists. However, this is not at all safe, since gasoline can easily damage rubber or plastic parts. In addition, when working with this flammable material it is necessary to observe extreme caution. Yes, and from strong smell in this case, it turns out to get rid no soon.
- Paragraphs 6-8 can be skipped if you use modern compositions specially intended for cleaning electrical contacts that are easily and quickly removed dirt and oxidation products. To do this, it is enough just to spray the product on the surface you want to clean. If necessary, you need to repeat the spraying until the desired result is reached. You can feed the voltage after applying such a cleaner after 15 minutes.
- Purified terminals are put on the reverse order - first connect "a plus" To the appropriate output of the battery and well tighten the terminal with a nut, then we are then done the same operation with minusa terminal.
How to prevent the oxidation of the battery terminals
As in many other cases, it is better to immediately take the necessary measures and prevent oxidation, and not to deal with the already appeared by the raid. This will significantly increase the battery life and will help prevent the occurrence of a number of serious problems in your car.
Protect the battery terminals using various methods with more or less high efficiency. We will tell about some of them, and what to choose - to solve you.
Folk ways
After talking with motorists, first-year-old-year-old, you will hear a lot of tips on how to protect the battery terminals with the help of Dedov's methods of varying degrees of creativity. Consider the safest of them.
Motor oil and felt or felt
One of the oldest methods tested by several generations (though, then there has not yet been effective protective compositions). It is extremely simple: from the material it is necessary to cut the ring of suitable size and impregnate it with engine oil. The resulting gasket is put on the output of the battery, and the terminal is fixed on top. The principle of operation lies in the fact that the wool felt gasket prevents the evaporation of the electrolyte and enter it on the battery terminals.
Various types of lubricants
Technical vaseline, solidol, lithol and other suitable compounds available in the arsenal of the motorist are applied to peeled and firmly tightened terminals with a thin layer. However, each of these products has its drawbacks. Thus, the solidol can roll into lumps in the river, Vaseline has bad conductivity and when hit between the contact and the terminal, it can significantly reduce the efficiency of the battery, and the lithol can be cleaned with the usual auto-mup.
UnfortunatelyThe considered defense methods cannot be called highly efficient, so specialists Recommend to use modern meansSpecially designed to protect the battery terminals.
Modern effective means
Today, any auto shop can easily find products specifically designed precisely to protect the battery terminals. Typically, manufacturers color such compositions in bright colors so that it can be easily distinguished by the processed surface from raw. The use of these efficient products will prevent terminal oxidation, which will ensure reliable contact and thereby increase the conductivity of the electric current. All of the above will reduce the battery self discharge and will help significantly increase its service life.
One of the most effective means intended to protect the battery terminals is the lubricant for the battery terminals of the famous Dutch brand Presto. This is a blue wax that reliably protects electrocontacts and poles of batteries from oxidation and corrosion, will prevent the electric current leakage and voltage loss. Another indisputable advantage of the product is that it is well compatible with plastic - now you can be absolutely calm for all plastic elements under the hood of your car!
Presto battery lubrication:
- Reliably protects the terminals of the AKB from corrosion and oxidation
- Provides quick start and optimal car lighting
- Prevents acid damage
- Reduces resistance
- Reduces the risk of current leakage
- Configuously isolates contacts
- Prolongs battery life
- Has aiming jet
Presto battery lubrication is very easy to use - after all, the tool can be sprayed in any position. Shake the cylinder well and apply a thin layer of a protective spray to a dry and clean surface (if necessary, you can use the Presto universal cleaner and the Presto electrical contact cleaner). You can easily control the process of applying the product, because the composition has a bright blue color. This allows you to create a uniform coating and not to leave a single untreated area. Now you can be sure that the terminals of your battery are securely protected!
So, if you want your battery to serve for a long time, and its efficiency was maximum, the battery needs reliable protection. We told you about how to do it right, and now you can deal with the problem independently without resorting to expensive service of the car service. And the right tool will help make it easy and quickly!
When the car owner faces problems associated with the battery, it should not be slow. How to rinse the car battery correctly? The consequences of a faulty battery consist in the engine failure to work at a responsible moment.
This is how the creation of a situation that is dangerous to the driver of a faulty car, and other people participating in motion.
Battery must be urgently replaced or repaired. One of the recovery methods is its washing.
To wash the battery you will need a carometer, rubber pear, a load plug and a container where the electrolyte will be merged.
The need for flushing is determined by the following characteristics:
1. The electrolyte changed the color becoming brownish.
2. During charging, the battery is quickly charged to a complete charge, then fast discharge during operation. This means that the battery capacity has changed and decreased. Possible causes of this are deposits of salts or self-discharge of the AKB. Due to the contamination of the battery, the insulation resistance of the cover, current leakage and self-discharge of the battery has changed.
3. During the verification of the terminal voltage using the instrument, "0" or a figure corresponding to it is shown. Hence the sludge, fell to the bottom of the layer of plates being active, which is why the battery plates and short circuit occurred.
How to wash the car battery correctly - washing - it is, of course, not a panacea from the problems listed above, but if there is free time and you are limited to money, you can completely extend the life of the battery.
Washing the battery should be produced after preliminary battery discharge. Using a rubber pear you need to suck the electrolyte, then drain it into glass dishes (to dispose of in the future). Replace the electrolyte disgrace. The process should be repeated until the time is in banks there will be one distilled water without impurities. Battery with water must be left for a couple of hours. Then it is necessary to drain the water with a rubber pear. Electrolite should be added to banks, bringing the density to a value of 1.2.
Put the battery for charging. Charging should be carried out until constant battery voltage and electrolyte density are installed. Then bring the density to the norm (this is determined by the temperature that the air surrounding).
The most difficult case is crushing the plates with a cream sludge. To avoid deterioration of the situation, the battery should not shake and turn it up to it up so that the sludge of the sludge from the bottom does not occur, and the battery plates did not fall asleep. How to rinse the car battery correctly - this flushing is done during the overhaul of the AKB.
You need to cut down the "bank", then you should remove from the housing, from the housing using a rubber pear for this. Then you need to flush the jar several times using distilled water. Replace the sections of the plates and restore the electrical circuit of the battery. Seat the lid with mastic.
To ensure the safety of work with an acid electrolyte, you should work in glasses, protective apron and rubber gloves. If the electrolyte will accidentally fall on the skin surface you should rinse it using a lot of water. To reduce the density of the electrolyte, add distilled water to increase the electrolyte, but it is impossible to add acid.
How to rinse the car battery correctly we told - try to restore the battery with your own hands.
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:
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 / cm 3. 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 ,. 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 / cm 3. 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 / cm 3. The fusion was a liquid with a density of 1.15 g / cm 3. And where are the remaining 0.12 g / cm 3? And they are on minus plates in the form of a sulfatized plaque.
A person remembers the figure of 1.27 g / cm 3 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 / cm 3 are approached from the plates and are added to the total density of 1.27 g / cm 3, in sum, it turns out 1.39 g / cm 3, and this is a digit approximate to the corrective electrolyte density.
Therefore, in the case given for example, it would be necessary to simply spend.
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 a battery pack), filled to start the electrolyte with a density of 1.20 g / cm 3.
An electrolyte is agreed to increase the density, and distilled water. Clean sulfuric acid is not in any case.
