Do not leave the lithium-Ion battery discharged and unused for an extended
period because the battery will wear out and the longevity of the battery will
be at least shorter than half of the one with frequent recharges.
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 0°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 temperature of battery is over 50 degrees.
