11 LED Diagnostics and Acoustic Signals
1 A short beep
The acoustic signal works as it should.
2 Four or six (AR L) 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.
► Be aware that your ability to hear the acoustic signal may
be reduced when wearing hearing protection.
11.2.2 Power Tool Status
When the battery is connected to the power tool, the same
LEDs on the battery will indicate the status of the power tool.
If three LEDs glow red continuously: the power tool motor is
too hot. Allow the motor to cool down.
If three LEDs flash red when you activate the trigger switch:
the power tool has an electrical malfunction. Do not operate
the power tool. Have it checked by an authorized STIHL
servicing dealer before use or storage.

11.2.3 Charge Status
The LEDs and acoustic signals on the battery also indicate
the battery's state of charge.
To determine the battery's state of charge:
► Press the button (1) on the backpack battery.
A single short beep will be emitted. The LEDs on the battery
will glow or flash green for about 5 seconds and indicate the
state of charge (see illustration).
For example:
If six green LEDs glow continuously: full charge.
If one green LED is flashing and four long beeps are emitted:
less than 20 % charge.
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).
If the four right side LEDs flash red and a rapid
succession of several short beeps is emitted: the
battery has a malfunction and must be replaced.
Do not attempt to charge, use or store the
battery.
