Charging the Battery
The charging time depends on several factors, e.g.
temperature of the battery or the ambient temperature. The
actual charging time may differ from the specified charging
time. For specified charging times see
www.stihl.com/charging-times.
The charging process starts automatically when the plug is
inserted in a wall outlet and the AP adapter is fitted in the
charger. The charger switches itself off automatically when
the battery is fully charged.
The battery and charger heat up during the charging
process.
The STIHL AL 300 and AL 500 chargers have a built-in fan
which may cut in and out during the charging process.
