The battery maintenance of lithium battery manufacturers has the following points:

1. In order to reduce the self-discharge of the battery, the outer surface of the battery should be kept clean and dry.

2. Regularly check the liquid level of the electrolyte according to the manufacturer's instructions, and add distilled water to the maximum scale when necessary.

3. The battery should be stored in a place higher than -10℃ and lower than 35℃, and charged at least once every three months.

4. If the vehicle is idle for more than two weeks, it is recommended to disconnect the battery negative cable or turn off the main battery switch; if it is idle for more than two months, the battery should be removed.

5. For vehicles in normal use, the electrolyte density or open circuit voltage of the battery should be checked regularly. When the electrolyte density is lower than 1.2g/ml or the open circuit voltage is lower than 12.3V, the battery should be recharged to above 12.7V.
