Cautions for the Li-ion Battery
Pack
• If the temperature of the battery pack
falls approximately below −10°C (14°F),
charging will automatically stop to
prevent degradation of the battery.
Common Cautions for the Li-
ion/Ni-MH/Ni-Cd Battery Pack
• The ambient temperature range is
between 0°C (32°F) and 40°C (104°F).
If the battery pack is used when the
battery temperature is below 0°C
(32°F), the tool may fail to function
properly.
• Use the charger at temperatures
between 0°C and 40°C, and charge
the battery at a temperature similar to
that of the battery itself. (There should
be no more than a 15°C difference
between the temperatures of the
battery and the charging location.)
• When charging a cool battery pack
(below 0°C (32°F)) in a warm place,
leave the battery pack at the place
and wait for more than one hour to
warm up the battery to the level of
the ambient temperature.
• Cool down the charger when charging
more than two battery packs
consecutively.
• Do not insert your fingers into contact
