After insertion of the battery, the LED (3)
on the charger is on – see "Light-emitting
diodes (LED) on charger".
The charging process begins as soon as
the LEDs (4) on the battery are green –
see "Light-emitting diodes (LED) on
battery".
The charging time is dependent on
different factors such as battery
condition, ambient temperature, etc. and
can therefore deviate from the specified
charging times – see "Specifications".
The battery warms up in the machine
during use. If a warm battery is inserted
in the charger, it may be necessary for
the battery to cool off before charging.
The charging process does not start until
the battery has cooled off. The charging
time can be extended by the cooling off
period.
The battery and the charger warm up
during the charging process.
AL 300 charger
The charger is equipped with a fan for
cooling the battery. The fan can be
heard during operation.
KGA 770
AL 100 charger
The charger waits with the charging
procedure until the battery has cooled
off on its own. The battery is cooled by
the heat emitted to the ambient air.
Charging finished
Once the battery is completely charged,
the charger switches off automatically,
then:
the LEDs on the battery go out
–
the LED on the charger goes out
–
the fan on the charger switches off
–
(if present in the charger)
Remove the charged battery from the
charger after charging.
Light Emitting Diodes (LED)
on Battery
Four light emitting diodes show the
battery's state of charge and any
problems that occur on the battery or
power tool.
