Restoration of car batteries by one's own hands: technology, instruction and recommendations

Every driver knows that a rechargeable battery is exactly that part of the machine, without which no riding is possible. It is on it depends on its performance. After the battery is out of order, every motorist has the right to decide on his own what to do with it. Many are in a hurry to replace it, as the warranty period has expired. In order to be sure that the battery has exhausted itself, it is necessary to know the signs. The simplest of them are:

• Fast discharge of battery capacity;
• Frequent recharging.

There are many opinions on the rational use of this equipment. Most of the car owners believe that battery recovery is a completely pointless undertaking and waste of time. More economical drivers prefer to experiment and try to correct the shortcomings. What if she still serves for a while?

What is required to restore it?

We need the following components:

• electrolyte;
• Distilled water ;
• Device that allows you to measure the density of matter;
• Charger;
• Special desulfating additive.

Causes of malfunction

Before you carry out the restoration of car batteries, you need to understand the causes of the malfunction.

The basic malfunctions:

1. Sulphation of plates, contributing to the complete discharge of the battery.
2. Corruption of the electrolyte, which leads to the destruction of the carbon plates.
3. Evaporation of the electrolyte as a result of a short circuit. One of the most serious problems.

Important! A bloated and frozen battery is not recoverable! In order to never face the issue of restoring car batteries, it is necessary to take into account the recommendations listed below.

Recommendations for the care of equipment:

• Check the electrolyte density several times a month.
• Under low-temperature conditions of transport operation, the electrolyte density should be equal to 1.40 g / cu. cm.
• Its charging should be accompanied by a current 10 times lower than the capacity.
• At temperatures below -25 degrees it is forbidden to park vehicles in an open parking lot, since it is possible to freeze the battery, as a result of which it will fail.

Restoration of a car battery by one's own hands

Since it is an indispensable part of the machine, it is impossible to move without it at all. By type these devices are divided into acid, alkaline and lithium. In some cases, the acid is called lead-helium. Let's talk about this kind of batteries. Their main applications are cars and pocket flashlights. Their service life is small, but they are subject to repair. Consider the restoration of car batteries themselves.

Method number 1

This is a method of recharging a small current with short-term breaks between charges. Gradually, the battery begins to increase the voltage, it stops taking charge. During this time, the following occurs:

• Alignment of plates.
• Reduction of voltage on the battery during a short break. This is due to the spreading of a dense electrode into the interelectrode space. The recovery of the capacity of unattended car batteries occurs as the battery is filled. There is an increase in the density of the electrolyte, which contributes to its bringing into operational status.

Method No. 2

Complete replacement of electrolyte. Practiced in acid batteries. To do this, completely drain the electrolyte from the old battery and rinse it thoroughly with water. Flushing should be done several times. It will be better if the water is hot. Next, prepare a solution consisting of 3 tsp. Soda and a glass of water. Dilute with boiled water, pour again and wait for 20 minutes. Then you will have to repeat the procedure several times. It is desirable not less than 3 times. Restoring car batteries requires patience.

When the battery looks from the inside out like a new one, you can fill the electrolyte and conduct a new charge within 24 hours. It should be remembered! The restored battery needs to be charged once every ten days. The charge lasts for 6 hours.

Method number 3

By the method of "return". This will require additional equipment. The ideal option is a welding machine. The charging process must be carried out in the reverse order. Do not be alarmed if the battery starts boiling. This is a normal process for this method. The charging time is half an hour. After the procedure, you need to drain the old electrolyte, thoroughly rinse the parts and fill in a new one. Then take the usual charger 10A-15A and recharge the recovered battery. Attention, do not get confused! After repair, the factory plus will become a minus, and vice versa.

Method No. 4

Fastest and most effective. The battery can fully recover within an hour. A discharged battery is precharged and the electrolyte is drained. Then a thorough rinse should be carried out. In a clean battery, fill with an ammonia solution consisting of 2% trilon and 5% ammonia. The process of desulphation will begin, which will be accompanied by a spray. The cessation of the release of gases will indicate that the process is nearing completion.

If the sulphation is too strong, this indicates that you need to repeat the treatment with the solution. After cleaning, rinse the battery again. Now it is ready to be filled with a new electrolyte. Then the capacity of the car battery is restored. It should be equal to the one recommended in the technical passport. As you can see, recovery of car batteries is possible. And this is not a myth. To facilitate the work there is a device for the recovery of car batteries. It is used in case of failure as a result of improper operation. Usually they have a zasulphated form.

What does this method give?

This method allows:

• Quickly carry out battery recovery;
• Use the device for preventive purposes.

There is also a technique for restoring the element by charging with an asymmetric current. Restoration of car batteries, the scheme of which is shown below, is capable of providing an accelerated charge.

The failure of the battery can be associated not only with the expiry of the expiration date, but also because of its long inactivity. If this happened, you need to do an urgent resuscitation and bring it to life. To do this, you need to restore the car battery charger. Immediately, the question arises as to which device will cope with the task faster and better. It turns out that charging should have a higher voltage rating than the battery.

All of them are divided into the following groups:

1. Transformer, having a transformer and a large rectifier.
2. Pulse - able to work from a lightweight transformer.

This article covers all the main ways to repair the battery, including the restoration of an unattended car battery. In conclusion, I want to draw your attention to the fact that only the prevention of malfunctions can prolong the service life of the equipment. To do this, you must carefully treat each part of the part. Carry out regular maintenance. To be guided by the technical specification, which is attached to the element when buying it.

Conclusion

The battery itself does not require close attention. The main thing is to recharge it in time. Do not save on the purchase of a quality charger. It is better to shell out once and be sure that it will always be at hand at any time. Before installing for charging, monitor the electrolyte level. If it does not comply with the norm, remove the defect. When performing this action, do not forget to pay attention to the density that you need to check in each bank. Differences between the indicators should not be. The minimum error is allowed. Before installing the battery carefully check the voltage that the generator gives to prevent overcharging. When installing only the purchased battery on the car, please fix it firmly, to avoid damaging the parts.
