whether the battery is dead or not.

Reason: there is no input voltage.
Solution: Connect to a 110-220V AC socket.
3. The battery can't be charged and is low current, but the screen display (FUL) indicates
fully charged.
Reason: This is caused by the battery's vulcanization and inside lack of water, low voltage or
leave it unused for a long time. The internal resistance of the battery and capacity will reduce
greatly, Then it will reach full voltage quickly while charging.
