● Push battery (1) into charger (2) until
first resistance is felt, then press to
stop. Green LED on battery and
charger (3) indicate that charging is

Charging procedure
The charger automatically detects the
battery type and adapts the charging
process accordingly.
The batteries are cooled during the
charging process – via a fan on the quick
charger
(AL 300, AL 500) and with the
natural air current in the room on the
standard charger
(AL 1 00) .
The LEDs on the battery indicate the
charging status (
Ö 8.5).
When the battery is fully charged, the
charger switches off automatically and the
LEDs in the battery and charger
extinguish.
The charging time depends on various
influencing factors such as e.g. the battery
condition and ambient temperature and
can therefore deviate from the specified
charging times (
Ö 19.).
If a warm battery is inserted in the charger,
the charging time may increase because
the battery must cool down before the
charging process begins.
