If your electric scooter battery isn’t charging, several common issues could be at play. The battery might be dead, the charger could be faulty, connections may be loose, the battery might be overheating, or there could be issues with the Battery Management System (BMS). Start troubleshooting by checking the charger, inspecting the battery connections for cleanliness and damage, and testing the charger with another device. If necessary, reset the BMS or replace the charger. If the battery is the issue, replacing it may be your best option.
