Generally, the battery life of an electric motorcycle is 400 times of full charge and discharge. The battery is a consumable, and the price is relatively high. Therefore, it is very necessary to use and maintain the battery correctly and extend the service life of the battery to achieve the best use of the material. Battery life is generally calculated based on the number of times the battery is fully charged and discharged.This 400 times is calculated when the battery capacity drops to 75% of the nominal capacity. This data is very important because the user will not be when the battery is only 75% of the capacity. Just charge it, but charge it when there is really no way to use it. At this time, the battery capacity has dropped to 40% of the nominal capacity, that is, overdischarge has occurred. Therefore, do not store it at a loss. When the battery is not in use, charge it monthly once to extend battery life. Regular inspections should be performed. Do not discharge with high current. Try to avoid instantaneous high current discharge. High current discharge will easily lead to lead sulfate crystallization, which will damage the physical properties of the battery plate.
