Most motorists, rejoicing that at least the battery has served its warranty period, get rid of it. Rapid loss of capacity, frequent recharging - they say, as they think, about the impending death of the battery. Is this really so, and is it possible to restore a car battery?
Necessary
- - Charger;
- - ammonia solution of Trilon B (ethylene diamine tetra sodium acetate);
- - distilled water;
- - fresh electrolyte.
Instructions
Step 1
In the practice of craftsmen, several methods are used to restore the performance of batteries. Among them, for example: low current overcharge and deep discharge battery treatment. These methods require the almost constant presence of a person and take a long time - up to several days.
Step 2
The electrochemical method of restoring a car battery is carried out using a special charger. Batteries recover when charged with an asymmetric current. This method allows you to restore sulphated battery batteries, as well as carry out preventive treatment of serviceable batteries.
Step 3
The most radical and fastest way to restore a car battery is chemical. To carry out a chemical recovery of the container, you will need an ammonia solution of Trilon B (ethylene diamine tetra sodium acetate), which contains 2% Trilon B and 5% ammonia.
Step 4
Fully charge the battery before proceeding with chemical recovery. After that, carefully, with the observance of precautionary measures, pour out all the electrolyte from it. Then rinse, preferably with distilled water 2-3 times.
Step 5
Pour the prepared ammonia solution of Trilon B into a thoroughly flushed battery. Leave the battery in this state for desulfation, which will be accompanied by gas evolution and the formation of small splashes. After 40-60 minutes, gas formation will stop, which will indicate the completion of the process.
Step 6
Drain the solution and rinse the battery again 2-3 times with distilled water. Fill the jars with electrolyte of standard density and charge up to the nominal capacity. Everything. The restored battery will serve for another 2-3 years.
