10.2 Charging

WARNING
STIHL batteries contain safety features and devices which,
if damaged, may allow the battery to generate heat, rupture,
leak, ignite or explode. Never charge a malfunctioning,
damaged, cracked, leaking or deformed battery or use a
charger that has been damaged. Never insert a wet battery
or adapter. Never use a wet charger. Follow all product-
specific warnings and instructions accompanying your
battery and charger.
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 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.
Charging time depends on a number of factors, including
battery condition and the ambient temperature. For a
complete list of approximate charging times, see
