Can I wash the battery. Correct car battery care
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:
The causes of the above features are:
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 / 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.
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").
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.
Hi friends! Today I want to tell you another simple effective way, how to extend the service life with its old battery. We all well know that the acid-lead battery thing is not eternal. And even if you carefully follow on them, sooner or later it will still begin fail. The reason for this is the sulfate of the plates, as a result of which the battery loses its container and is no longer able to perform the specified functions.
I want to clarify that the method described below is suitable only for the accumulated batteries. It is not suitable for batteries with closed or swollen banks, with shivened plates, etc.
Obvious signs of sulfate plates
The most obvious feature is that the battery does not hold the load. That is, when the voltage measurements on the terminals, the voltmeter shows a fully charged battery, and when the load is connected, the voltage varies significantly.
The second feature is a quick self-discharge. For example, you did not use the day of the day 3. Come to the garage and try to start. And the battery is greatly discharged that even the electronics does not show its values.
All these phenomena do not occur immediately, and they come gradually, usually after 3-5 years of operation of the battery.
Car battery recovery
First of all, it is necessary to measure the initial voltage.
I have long noticed an increase in the self-discharge, so today it is in general discharged.
It will not be superfluous to check the density of the electrolyte.
After the battery is diagnosed and the diagnosis is delivered, go to restoration.
The hydrometer is drained from above the electrolyte as possible. As you can see, his color is dark.
Now we turn the battery and drain the remnants of the bucket. It is necessary to do it particularly carefully and rotate the case when pluming so that the row of holes can be horizontally. This should be done in order for the winding jets of the electrolyte not closed among themselves.
Well, here it is completely black with a lot of impurities.
Now it is necessary to find a capacity under the battery. I took the pelvis.
Using the flow water by promoting all the cans with ordinary water. Fill home.
And merge.
Thereby remove the remnants of the electrolyte and black flare.
We divor her with 5 liters of ordinary water in the canister. And mix well.
Pour into each compartment to the edges.
Everything starts to spill. Top in the compartments where many soda solutions resulted.
Let's wait 15 minutes until the reaction is complete. And drain the solution.
We merge a little longer so that there is a minimum of excess water.
I fired earlier electrolyte I will fill back - new is not needed. But for this it must be filtered. Using a filter using a synthetic napkin.
Place it in a funnel.
And gradually filter the entire previously fused electrolyte.
Then gradually pour it back to banks.
We wait until the bubbles come out, pour if necessary. All wipe dry dry and close the lids.
Measure the tension. It is without changes practically.
We charge for an hour.
The battery is charging. Current when charging is a witness. Voltage has grown.
The test for the load fork is proves.
Now put the battery for the full charging cycle.
After time, the battery charged and became fully operational.
A bit of the theory of the process
In this method there is no focus, pure chemistry. The fact is that sulfate located on the plates react with a solution of soda and is etched. That's all.
Of course, the method does not give 100% guarantee that the battery will return to life, but still you can try.
So far.
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 should 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.
