10 LED Diagnostics
10.1 LEDs on the Battery
10.1.1 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 temperature 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.
10.1.2 Lawn Mower Status
When the battery is inserted in the lawn mower, the same
LEDs on the battery will indicate the status of the lawn
mower.
If three LEDs glow red continuously: the lawn mower motor
is too hot. Allow the motor to cool down.
If three LEDs flash red when you activate the trigger switch:
the lawn mower has an electrical malfunction. Do not
operate the lawn mower. Have it checked by an authorized
STIHL servicing dealer before use or storage.
For troubleshooting information, @ 24.
10.1.3 Charge Status
The LEDs on the battery also show the battery's state of
charge.

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