Most common causes

Defective or incorrect charger

Check if the light on the charger turns red during charging. The H9 charges with the 1-pin Ouxi charger. View chargers.

Dirty or damaged charging port

Look inside the charging port on the battery: dirt, bent pins, or corrosion cause poor contact. View batteries.

Deeply discharged battery

If the battery has been empty for months, the protection system (BMS) may block charging. Have it tested before you buy a new one. View batteries.

Battery at the end of its life

After many charge cycles, the capacity decreases. If it still charges fully but runs out quickly, replacement is often necessary. The H9 uses the 15Ah battery that also fits in the V8 and C80. View batteries.
