Battery Charge Notice
It is important to consider the environment temperature whenever the Lithium-Ion
battery pack is charged. Charging is most efficient at normal room temperature or in a
slightly cooler environment. It is essential that batteries are charged within the stated
range of 10°C to 40°C. Charging batteries outside of the specified range could
damage the batteries and shorten their charging life cycle.
CAUTION!
Do not charge batteries at a temperature lower than 0°C, which will
increase the internal resistance to cause heat and make the batteries
unstable and unsafe. Please use a battery temperature detecting
device for a charger to ensure a safe charging temperature range.
Further, to protect and avoid battery from inflating, the battery is
detected for thermal protection and will not be charged when the tem-
perature of battery is over 50 degrees.
Storage and Safety Notice
Although charged Lithium-Ion batteries may be left unused for several months, their
capacity may be depleted due to build up of internal resistance. If this happens they
will require recharging prior to use. Lithium-Ion batteries may be stored at
temperatures between -20°C to 60°C, however they may deplete more rapidly at the
higher temperature ranges. It is recommended to store batteries within normal room
temperature ranges.
