Auto batteries will not have any symptoms in the early use. Once there is a problem, the battery basically needs to be replaced, so the maintenance of the battery should start from the new car or after installation.

　　1). The first charge of a new battery or a repaired battery before use is called initial charge. Whether the initial charge is proper or not is extremely important to the future performance of the battery. The characteristics of initial charging are low charging current, long charging time, and sufficient electrochemical reaction. The initial charging of a new battery should be carried out one to three charge and discharge cycles.

　　2). Each start time should not exceed 5s, the start interval should be greater than 15s, and a maximum of 3 consecutive starts.

　　3). If you encounter traffic jams or waiting for people, in order to save fuel, most car owners are accustomed to turning off the engine and listening to audio or watching DVDs in the car, but this will consume a lot of battery power. It is recommended that the owner of the car should not listen to the radio for more than 30 minutes when the flame is turned off, and high-power devices such as DVDs and external power supplies are not recommended to use, because this will easily consume the power stored in the battery and damage the battery itself. Not small, it will also affect the normal starting of the vehicle.

　　4). If your car will not be used for a long time, it is best to unplug the negative electrode of the battery. Because there is also weak current consumption in the vehicle circuit system when parking, leaving the vehicle for a long time will cause the battery to run out.

　　5). Wipe the outside of the battery with a damp cloth, and wipe clean the dust, oil, white powder, etc. on the panel and on the pile head (ie, the positive and negative poles) that may cause leakage. In this way, the battery is often scrubbed, the pile head of the battery will not only not accumulate white acid powder, but also its service life will be longer.

　　6). Do not just replace the car with a battery with a larger capacity than the original battery. Because the power generation of car generators is fixed. If the battery is replaced with a large capacity battery, the new battery will be insufficiently charged, the car will not start smoothly, and the long-term loss of the battery will shorten the life.

　　7). When using maintenance-free storage batteries, simply think that maintenance-free storage means that no maintenance is required. After over-discharge, charging is not performed in time, and supplementary charging is not performed regularly, which affects the service life of the storage battery.

　　8). The battery should be firmly fixed on the car, and should be handled with care during installation and transportation.

　　9). When using the battery in winter, special care should be taken to keep it in a fully charged state to prevent freezing. When adding distilled water in winter, it should be done during charging to prevent freezing. The capacity of the battery will decrease in winter, and it is best to warm up the engine before starting. Due to the low temperature in winter, it will be difficult to charge the battery. You should always check the battery's storage status.
