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 lawn mower. 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

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.
