11 Charging the Battery
WARNING
A typical household electrical circuit is between 15 and
20 amps. A single STIHL AL 1 charger draws approximately
0.275 amps. To reduce the risk of fire from overloading an
electrical circuit:
► Ensure the electrical system is rated to withstand the
expected electrical draw before charging your battery.
► Charge multiple batteries one at a time or on separate
circuits, unless you know your circuit can handle the total
expected draw from multiple chargers.
WARNING
Since the battery and charger heat up during the charging
process, do not operate the charger on a combustible
surface or in a location where combustible gases, liquids,
vapors, dusts or other materials are present, @ 8.
To set up the charger:
1
► Insert the plug (3) into a properly installed electrical
outlet (4) matching the voltage and electrical frequency
stated on the charger's rating plate.
The charger runs a self-test immediately after it is plugged
in. The LED (1) will glow green for about 1 second, then it
will glow red briefly before going out. Once the LED goes
out, the self-test is complete and the charger is ready to
charge the battery.

► Position the power supply cord (2) 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.
11.2 Charging
WARNING
STIHL batteries contain safety features and devices which,
if damaged, may allow the battery to generate heat, rupture,
leak, ignite or explode. Never charge a malfunctioning,
damaged, cracked, leaking or deformed battery or use a
charger that has been damaged, @ 8. Make sure the
charger and the battery to be charged are both completely
dry before charging, @ 8. Follow all product-specific
warnings and instructions accompanying your battery.
To charge the battery:
1
► Push the battery (1) into the charger (2) until it stops.
The LED on the charger (3) glows or flashes green when
the battery is charging.
When the LED on the charger goes out, the charging
process is complete and the charger will shut itself off. The
battery can be removed from the charger.
► Disconnect the power supply cord from the electrical
outlet when the charger is not in use for extended periods
of time.
A battery is not fully charged when it ships from the factory.
STIHL recommends that you fully charge the battery before
using it the first time.
