The most important point is to charge properly: Some people say that "the battery is not broken but is broken", this statement is really correct. The battery charging performance plays an important role in the service life and performance of the battery, so it is necessary to pay attention to the charging method. According to the situation of most users, it is best to choose the best charge when the battery is discharged at a depth of 50%-70%, which can achieve the best battery life. At the same time, the effect of temperature on charging is quite large. During the hot season, the battery has an overcharge problem. The battery temperature should be reduced as much as possible to ensure good heat dissipation and prevent charging after sun exposure. The sun exposure will increase the battery temperature, and the activity of various active substances in the battery will increase, which will affect the service life of the battery. On the contrary, in the case of low temperature, the battery has the problem of poor charging acceptance and insufficient charging. In this case, it is necessary to increase the charging voltage and prolong the charging time, and take measures of heat preservation and antifreeze, so as to ensure sufficient power. Extend the battery life.
