A Lithium-Ion battery is at the end of its life cycle if there is a 20 percent
decrease in performance.
A battery’s life cycle depends on the type of battery and the device configuration. Con-
serve the battery’s life through the following:
• Avoid frequent full battery discharges, because this places additional strain on
the battery. Several partial battery discharges with frequent recharges are bet-
ter than full recharges. Recharging a partially charged Lithium-Ion battery does
not cause harm.
• Keep the Lithium-Ion battery in cool environment, and especially avoid hot cars.
Keep the battery at a 40 percent charge level for prolonged storage periods.
• Do not leave the Lithium-Ion battery discharged and unused for an extended
time period.
Battery Charge Notice
It is important to consider the environmental temperature whenever the Lithium-Ion
Battery Pack is charged. Charging is most efficient at room temperature or in a slightly
cooler environment. It is essential that batteries are charged within the temperature
range of 50°F - 104°F (10°C to 40°C). Charging batteries outside of this specified tem-
perature range could damage the batteries and shorten their charging life cycle.
CAUTION! Do not charge batteries at a temperature lower than 32°F (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.
Storage and Safety Notice
Charged Lithium-Ion batteries may be left unused for several months, but their capac-
ity may deplete due to buildup of internal resistance. In this case they will require
recharging. Lithium-Ion batteries may store at temperatures between -4°F - 140°F (-
20°C to 60°C). But the batteries may deplete more rapidly at the warmer end of this
range. It is recommended to store batteries at room temperature.
