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 half of the one with frequent recharges.
Battery charge notice
It is important to consider the environment temperature when the Lithium-Ion
batterypackischarged.Chargingismostefcientatnormalroomtemperature
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

cycle.
CAUTION! Do not charge batteries at a temperature lower than 0°C. This
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.
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 higher temperatures. It is recommended to store batteries at
room temperature.
