During the operation of the vehicle, it is particularly difficult to maintain a reliable charge-discharge balance of the vehicle electrical system due to the increased power of the engine when the low-temperature cold vehicle starts and the complicated electrical equipment installed in the vehicle. This situation is more obvious when driving in urban areas. During the parking of the vehicle, due to the self-discharge effect of the battery itself and the sleep current required by the anti-theft control unit, the battery always consumes a certain amount of current. If the vehicle is parked for a long time without being charged, the battery will be damaged. The characteristics of the battery determine that regular inspection and maintenance are required. The operation is as follows:
1) Check the liquid level of the electrolyte regularly according to the manufacturer's instructions, and add distilled water to the maximum scale if necessary.
2) In order to reduce the self-discharge of the battery, the outer surface of the battery should be kept clean and dry.
3) For vehicles in normal use, the battery electrolyte density or open circuit voltage 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.
4) If the vehicle is idle for more than two weeks, it is recommended to disconnect the battery negative cable or turn off the battery main switch; if it has been idle for more than two months, the battery should be removed.
5) The battery should be stored in a place higher than -10℃ and lower than 35℃, and charged at least once every three months.
