The most taboo thing about lead-acid batteries is to charge them when they have been discharged cleanly. In this case, the battery life will be greatly reduced. Do not discharge deeply for many times. The so-called deep discharge refers to the undervoltage of electric vehicles. After the power is cut off, it is absolutely impossible to continue to power on and drive. The intermittent discharge of the battery of the electric vehicle will hurt the battery the most. If you encounter an electric vehicle undervoltage and power failure during driving, it is best to get off the vehicle, close the electric door lock, and push the vehicle to drive. Hope to help you!

1. Charge when the battery indicator shows one third of the remaining battery.
2. The charging environment should be kept dry and tidy, and the charger should not be wrapped in plastic bags or plastic bottles, because it is very easy to burn when the charger cannot breathe.
3. Try not to use fast charging, if not necessary, do not use it more than twice within a month.
