If the battery does not charge anymore, please check and make sure that the charging port is clean and free from obstructions. Issues with charging may also be caused by the charger itself. 

Plug the charger in but keep it disconnected from the kick scooter. Check if the charger indicator is green. If it is red or not lit at all, the charger may be damaged. In this situation Please contact our after-sales team service for repairs or replacement.
