  If the LED on your Stihl Battery Charger flashes red, it could be due to a few reasons. First, there might not be proper electrical contact between the charger and the battery; try removing the battery and then reinserting it into the charger. If the LED continues to flash, there may be a malfunction with the battery, especially if 4 LEDs on the battery are flashing, indicating it needs replacement. If not, have the battery checked by a Stihl servicing dealer. Alternatively, the charger itself might be malfunctioning, in which case you should also have it checked by an authorized Stihl servicing dealer.

  If your Stihl Battery Charger doesn't run a self-test, it might be because the electrical contact to the charger was briefly interrupted. To resolve this, disconnect the plug from the electrical outlet, wait for one minute, and then plug it back into the outlet.
