Why is my Stihl FSA 65 Trimmer battery not charging when the charger light is green?
- C
  Craig MartinSep 13, 2025
  If your Stihl Trimmer battery isn't charging even when the light emitting diode on the charger glows green, the battery may be too hot or too cold (1 light emitting diode on the battery glows red). Allow the battery to cool down or warm up slowly at a temperature between 15°C and 20°C. Operate the charger indoors only in dry locations at an ambient temperature between +5°C and +40°C.

What does it mean when the light emitting diode on my Stihl FSA 65 Trimmer charger flashes red?
- D
  Debra NguyenSep 12, 2025
  A flashing red light emitting diode on your Stihl Trimmer charger could indicate several issues. First, there may be no electrical contact between the charger and the battery; remove the battery and refit it again. Second, it could indicate a fault in the battery (4 light emitting diodes on the battery flash red for about 5 seconds); take the battery out of the power tool and refit it. Switch on the power tool – if the light emitting diodes still flash, the battery is faulty and must be replaced. Finally, it might indicate a fault in the charger.

  If the battery is not being charged, even though the LED on the charger glows green, the battery may be too hot or too cold (indicated by one red LED glowing on the battery). Allow the battery to cool down or warm up slowly to a temperature between 15°C and 20°C. Operate the charger only in closed, dry rooms with ambient temperatures between +5°C and +40°C.

Why won't my Stihl FSA 65 Trimmer start?

  Michael MurphyAug 23, 2025
  If your Stihl Trimmer does not start when switched on, several factors could be at play. First, check for electrical connectivity issues between the power tool and the battery by removing and refitting the battery. If the battery's charge is low (indicated by one green LED flashing), charge it. If the battery is too hot or cold (one red LED), allow it to reach an optimal temperature (around 15-20°C). For a faulty battery (four red LEDs flashing), replace it. Overheating of the power tool (three red LEDs) also prevents starting, so let it cool down. In case of electromagnetic issues or a machine fault (three red LEDs flashing), have the power tool checked by a servicing dealer. Lastly, ensure no moisture is present in the power tool or battery; if there is, allow them to dry.

  If your Stihl Lawn Mower battery isn't charging even when the LED on the charger glows green, the battery might be too hot or too cold (1 LED on the battery glows red). Allow the battery to cool down, or if it's too cold, allow it to warm up slowly at temperatures between 59°F - 68°F (15°C - 20°C). Ensure you operate the charger in closed, dry rooms at ambient temperatures of 41°F - 104°F (5°C - 40°C).

  Chad HerreraSep 8, 2025
  If the running time of your Stihl Lawn Mower is too short, several factors could be responsible. Ensure the battery is fully charged. If not, charge the battery. The issue might be the nylon line; consider replacing it if it's unsuitable. Also, the battery's lifespan could be over; consider checking and replacing it if necessary.

Why does my Stihl Lawn Mower keep cutting out?
- W
  wparsonsSep 7, 2025
  If your Stihl Lawn Mower cuts out during operation, it might be because the battery or the machine's electronics are too hot. Remove the battery and allow both the battery and the machine to cool down. Another possible cause is an electrical fault. In this case, remove the battery and then refit it.

Why is the running time too short on my Stihl Trimmer?
- G
  Gary CampbellSep 6, 2025
  If your Stihl Trimmer's running time is too short, it could be because the battery is not fully charged, so you should charge the battery. It could also be due to using an unsuitable nylon line, which means you should replace the nylon line. Another reason could be that the battery's useful life has been reached or exceeded, in which case you should check and replace the battery.

Why does my Stihl FSA 65 runtime is too short?
- G
  gbrownSep 5, 2025
  A short runtime for your Stihl Trimmer may be due to the battery not being fully charged. Recharge the battery fully as described in the instruction manual for the STIHL AL 101, 300, 500 chargers. Alternatively, the battery's normal life may have been exceeded, indicating it's time to replace it.
