charger's manual. For optimum performance, STIHL
recommends operating the charger within an ambient
temperature range of 41 °F to 104 °F (5 °C to 40 °C).
WARNING
A typical household electric circuit is between 15 and 20
amps. A single STIHL AL 500 charger draws approximately
4.8 amps. A single AL 301 or AL 301-4 charger draws
approximately 4.4 amps and an AL 101 approximately 1.3
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 charger heats 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 and substances are present.
To set up the charger:

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 charger 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.
12.2 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. Never insert a wet battery
or battery adapter. Never use a wet charger. Follow all
product-specific warnings and instructions accompanying
your battery and charger.
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.
Read and follow the warnings and instructions in your
charger's manual. For optimum performance, STIHL
recommends operating the charger within an ambient
temperature range of 41 °F to 104 °F (5 °C to 40 °C).

The battery heats up during operation of the power tool. If a
hot battery is connected to the charger, it may be necessary
for it to cool down before charging starts. 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
