2.12. Check, maintenance and accumulator charging

Attention! The hydrogen vapors which are contained in accumulator sections are explosive. Electrolyte is served by the diluted sulfuric acid which will cause
chemical burn at hit on skin or in eyes. At a detachment of wires of the accumulator always disconnect a wire of the minus plug of the accumulator the first and connect his last.

11.1 Tools and materials necessary for maintenance of the accumulator
1. Goggles or guard
2. Baking soda
3. Technical vaseline
4. The tool for cleaning of contacts of the accumulator
5. Felt washers
6. Stripper
7. The tool for cleaning of contacts
8. Rubber gloves


Check, maintenance
1. If on the car the factory accumulator which is not demanding maintenance is installed, then you do not need to check the level of electrolyte and to add the distilled water. If the accumulator was replaced on usual, then it is necessary to perform the following operations of maintenance.
2. Remove caps and check electrolyte level in accumulator sections. It has to cover plates completely. If it is necessary, add the distilled water.

3. Check a condition of the case of the accumulator, reliability and purity of contacts (11.3a, 11.3b, 11.3v and 11.3g).
4. Check the shelf of the accumulator and reliability of a fixing clip. Remove the formed corrosion by means of baking soda.
Recharge of the accumulator
5. Remove all caps of the accumulator. Disconnect a wire of the minus plug and connect the charger.
6. With the force of charging current over 2 Ampere, regularly check the accumulator that it did not overheat. If you use the charger with small charging current, it is possible to leave the accumulator to be recharged for the night.
7. Check electrolyte density by means of the areometer each hour within the last several hours of recharge. The accumulator can be considered loaded when density of electrolyte does not change within two hours. Density of electrolyte has to be approximately identical in all sections of the accumulator. If is not present probably some sections are damaged.
