11 LED Diagnostics and
Acoustic Signals
11.1 STIHL AP Battery
11.1.1 Battery Status
Four LEDs show the status of 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 tempera‐
ture of about 50 °F to 68 °F (10 °C to
20 °C).
If all 4 LEDs flash red: the battery has
a malfunction and must be replaced.
Do not attempt to charge, use or store
the battery.
11.1.2 Power Tool Status
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.
For troubleshooting information,
11.1.3 Charge Status
The LEDs on the battery also show the battery's
state of charge.
To determine the battery's state of charge:

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 four green LEDs glow continuously: full charge.
12
If one green LED is flashing: less than 20 %
charge.

11.2.2
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

battery. Replace the battery.
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 tempera‐
ture 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
