Remember not to discharge the battery to 0%, otherwise the battery will be easily damaged.
After the battery is exhausted, please charge it in time. If it is not charged for a long time, the battery may be damaged.

If you often use it with a charger, please use the battery power regularly and use it more than once a week.
