Note: Before you prepare your STIHL product for use, put it into operation, clean, transport, store, maintain, repair, troubleshoot or dispose of it, please read the instruction manual carefully. The instruction manual contains safety instructions and supports you in using your STIHL product in a safe and environmentally friendly manner over a long service life.

The temperature of the battery and charger increases during the charge process.

The temperature is monitored over the entire charge process. If the temperature rises above a certain limit, the charge process is automatically interrupted until the temperature drops to the approved level. The charge process is then continued automatically. This avoids the battery and charger overheating.

The AL 300 and AL 500 chargers are equipped with a fan which is switched on and off automatically to actively cool the charger and battery during the charge process. The fan runs continuously on first generation chargers.
