  If the LED on your Stihl Trimmer charger glows green but the battery isn't charging, it might be because the battery is too hot or too cold. Allow the battery to warm up or cool down gradually to an ambient temperature of about 50 °F to 68 °F (10 °C to 20 °C). Also, ensure you operate the charger in a dry, enclosed room with a temperature between 41 °F to 104 °F (5 °C to 40 °C).

Why my Stihl FSA 56 Trimmer does not start?
- J
  Jessica WalkerAug 26, 2025
  If your Stihl Trimmer doesn't start, several factors could be the cause. First, the battery may have a low charge, so try charging it. The battery might also be too hot or too cold; in this case, remove it and allow it to cool down or warm up. There may be no electrical contact between the trimmer and battery; try removing the battery and cleaning the contacts in the battery compartment before refitting it. Also, the trimmer might be too hot, so allow it to cool down. If the trimmer or battery is damp, allow them to dry. If 3 LEDs continue to flash red, or if 4 LEDs continue to flash red after reinserting the battery, do not use your trimmer or battery and contact your STIHL dealer for assistance.
