Charging the Battery

A factory-new battery is not fully
charged.
Recommendation: Fully charge the
battery before using it for the first time.
Connect the charger to the power
N
supply – mains voltage and
operating voltage of the charger
must be the same – see
"Connecting Charger to Power
Supply".
Operate the charger only in enclosed
and dry rooms at ambient temperatures
between +5°C to +40°C (+41°F to
+104°F)
Only charge dry batteries. Allow a damp
battery to dry before charging.
Push the battery (1) into the
N
charger (2) until noticeable
resistance is felt – then push it as far
as stop.

The LED (3) on the charger comes on
when the battery is inserted – see "LED
on Charger"
Charging begins as soon as the
LEDs (4) on the battery glow green –
see "LEDs on Battery".
The charge time is dependent on a
number of factors, including battery
condition, ambient temperature, etc.,
and may therefore vary from the times
specified.
The battery heats up during operation in
the power tool. If a hot battery is inserted
in the charger, it may be necessary to
cool it down before charging. The
2
charging process begins only after the
battery has cooled down. The time
required for cooling may prolong the
charge time.
The battery and charger heat up during
the charging process.
AL 300, AL 500 Chargers
The AL 300 and AL 500 chargers are
equipped with a battery cooling fan
3 4
AL 100 Charger
The AL 100 charger has no fan and
waits for the battery to cool down before
starting the charging process. The
battery is cooled by heat transfer to the
ambient air.

automatically when the battery is fully
charged:
