Description: When a Festool 18V battery refuses to accept a charge, it often needs to be ‘woken up’ so the charger can detect it; during this condition the charger will show a blinking red light. The common fix is to connect a healthy Festool 18V pack or any compatible 18V‑20V battery to the charger. This method resets the pack, especially useful when the cell is trapped in a low‑voltage condition.
