  If the LED on your Stihl Lawn Mower charger flashes red, there could be a few reasons. First, check the electrical contact between the charger and the battery by removing and refitting the battery. Another cause might be a fault in the battery (indicated by 4 LEDs flashing red for about 5 seconds); remove and refit the battery, and if the LEDs continue to flash, the battery needs replacing.

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.

- 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 is the running time too short on my Stihl Trimmer?

  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.
