falls approximately below −10°C
(14°F), charging will automatically
stop to prevent degradation of the

• The ambient temperature range is
between 0°C (32°F) and 40°C (104°F).

(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 charg-
ing more than two battery packs
consecutively.
• Do not insert your fingers into contact
hole, when holding charger or any
other occasions.
