7 CHARGING THE BATTERY
To set up the charger:
► Insert the plug (4) into a properly installed wall outlet (5)
matching the voltage and electrical frequency stated on
the charger's rating plate (1).
The charger runs a self-test immediately after it is plugged
in. The LED (2) will glow green for about 1 second, then it
will glow red briefly before going out. Once the self-test is
complete, the charger is ready to charge the battery.
► Position the power supply cord (3) so that it will not be
stepped on, tripped over, come in contact with sharp
objects or moving parts or otherwise be subjected to
damage or stress.
7.2 Charging
WARNING
Never charge a malfunctioning, damaged, cracked, leaking
or deformed battery or use a charger that has been
damaged, @ 5. Make sure the charger and the battery to be
charged are both completely dry before charging, @ 5.3.
To charge the battery:
► Push the battery (2) into the charger (3) until it stops.
The LED on the charger glows green when the battery is
being charged.
The LEDs (1) on the battery glow green and show the
state of charge.
When the LEDs on the battery go out, the charging
process is complete and the charger will shut itself off.
► Remove the battery from the charger and disconnect the
power supply cord from the wall outlet.
A factory-new battery is not fully charged. STIHL
recommends that you fully charge the battery before using it
for the first time.
The STIHL AL 300 and AL 500 chargers are equipped with
an integrated fan. The fan may switch on and off
automatically while charging the battery.
Operate the charger only indoors, in dry rooms and within an
ambient temperature range of 41 °F to 104 °F (5 °C to
40 °C).
The battery heats up during operation. If a hot battery is
inserted into the charger, it may be necessary for it to cool
down before charging. The charging process begins only
after the battery has cooled down sufficiently.
Charging time depends on a number of factors, including
battery condition and the ambient temperature. For a
complete list of approximate charging times, see
