1. When charging, connect the battery first, and then connect to the AC power supply. After turning off the AC completely, pull out the battery connector. Pulling the battery connector during charging is easy to damage the charger, especially when the charging current is high (red light).
2. When the LED indicator turns green, continue charging for 2-3 hours.
3. Don't forget the battery and charger. Otherwise, you will not be able to protect the battery and it will not be damaged.
4. Long-term shallow discharge battery of about 3 months for deep discharge is called "re-lighting". This helps in the activation of long non-moving materials in the deep part of the battery. The indicator light means that the controller is protected from insufficient voltage.
5. Use the charger on time and in a dry place.
6. Always do not plug in the power supply when the charger is not in use.
