The LED on the charger (4) glows green when the battery
is charging.
The LEDs on the AR 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.
► Remove the AP Adapter from the charger and disconnect
the charger's power supply cord from the electrical outlet
when charging is complete.
A battery is not fully charged when it ships from the factory.
STIHL recommends that you fully charge the backpack
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 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.

9 LED Diagnostics and Acoustic Signals
9.1
Battery Status
Six LEDs and an acoustic signal indicate the status of the
battery.

3
1 A short beep
The acoustic signal works as it should.
2 Four long beeps
The battery's charge is low. Recharge the battery.
3 Rapid succession of short beeps
There is a malfunction in the battery. The signal stops
automatically after a few seconds. Do not attempt to
charge, use or store the battery. Replace the battery.
These LEDs can glow or flash green or red.
If one LED glows red continuously: the battery is
either too hot or too cold. Allow the battery to
warm up or cool down gradually at an ambient
temperature of about 50 °F to 68 °F (10 °C to
20 °C).
