(1) Keep the outer surface of the battery clean and dry, remove oxides on the pole posts and cable clamps in time, and make sure that the cable connections on the battery pole posts are firm.

When cleaning the battery, it is best to remove the battery from the car, rinse the entire shell with a soda solution, and then rinse the battery with clean water and dry it with a paper towel. For the battery bracket, first use a putty knife to scrape off the thick corrosive material, then clean the bracket with a soda solution, then rinse with water and dry it. After the bracket is dry, it is painted with anti-corrosion paint.


The pole posts and cable clamps can be cleaned with a soda solution first, and then cleaned with special cleaning tools. After cleaning, apply petroleum jelly or lubricating oil to the cable clamp to prevent corrosion.

Note: Before cleaning the battery, tighten the filling hole cap to prevent soda water from entering the battery.

(2) Keep the vent hole on the filling hole cover unblocked and unblock it regularly.

(3) Regularly check and adjust the electrolyte level. If the level is insufficient, add distilled water.

(4) Every time the car travels 1000km or 5-6 days in summer, and 10-15 days in winter, the storage should be checked once with a density meter or a high-rate discharge meter.

The discharge level of the battery. When the discharge exceeds 25% in winter and 50% in summer, the battery should be removed from the car in time for supplementary charging.


(5) Adjust the density of the electrolyte in time according to the changes of seasons and regions. In winter, you can add an appropriate amount of electrolyte with a density of 1.40g/cm3.

Increase the density of the electrolyte (generally 0.02~0.04g/cm3 higher than in summer).

(6) When adding distilled water to the battery in winter, it must be done before charging the battery to avoid uneven mixing of water and electrolyte, which may cause freezing.

(7) In winter, the battery should always be kept in a fully charged state to prevent the electrolyte density from falling and freezing, causing the shell to crack, the plate to bend, and the active material to fall off.
