11 Charging the Battery
the charger dry. Protect it from rain, water, liquids and damp 
conditions. Never insert a wet battery. Never use a wet 
charger, @ 11.2.
To charge the battery:
► Push the battery (2) into the charger (3) until it stops.
The LED on the charger (4) glows green when the battery 
is charging.
The LEDs (1) on the battery glow green and show the 
state of charge.
When the LEDs on the battery turn off, 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.
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 of the blower. If a hot 
battery is inserted into 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 
www.stihl.com/charging-times.
11.3 Mounting the Charger on a Wall
Before mounting, ensure that no electrical cables, pipes or 
other service lines run in the wall behind the charger.
To mount the wall charger:
► Mount the charger indoors in a dry room near an electrical 
outlet.
► Sink the screws into a wall stud. Use appropriate screw-in 
wall anchors or other similar mounting devices if an 
appropriate wall stud is not available.
► Align the charger as shown above. Mount to a wall with the 
following dimensions:
– a = minimum 18 in. (450 mm)
– b = minimum 3.9 in. (100 mm)
– c (for AL 101) = 3.0 in. (75 mm)
– c (for AL 300 and AL 500) = 4.7 in. (120 mm)
– d = 0.2 in. (4.5 mm)
– e = 0.4 in. (9 mm)
– f = 0.1 in. (2.5 mm)
