      If your Stihl Brush Cutter battery isn't charging even though the LED on the charger glows green, the battery might be too hot or too cold. Allow the battery to cool down or warm up slowly at a temperature of about 15°C - 20°C. Operate the charger only in closed, dry rooms at ambient temperatures between +5°C and +40°C.

      A flashing red light on your Stihl Brush Cutter charger indicates a few potential issues. There may be no electrical contact between the charger and the battery, so try removing and refitting the battery. It could also indicate a fault in the battery; in that case, take the battery out of the power tool and refit it. Switch on the machine – if the LEDs continue to flash, the battery has a malfunction and must be replaced. Finally, it could signal a fault in the charger, which would require a servicing dealer to check it.
