    Why is my Stihl Brush Cutter battery not charging?

      olucasAug 29, 2025
      If your Stihl Brush Cutter's battery isn't charging, it could be too hot or too cold. Leave the battery in the charger, and the charging process will start automatically once it reaches the correct temperature range. Alternatively, there might be poor electrical contact between the charger and battery. Remove the battery, clean the contacts on the charger and refit the battery. If these steps don't resolve the issue, there may be a malfunction in either the charger or the battery. In either of these cases, you should not use the affected component and contact your STIHL dealer for assistance.
