Even storing a battery in a hot environment can damage it irreversibly. When using your device

in a very cold environment, you may notice a decrease in battery life, but this condition is

temporary. Once the battery’s temperature returns to its normal operating range, its performance

will return to normal as well.

2) Store the device half charged when you store it long term

If you want to store your device long term, two key factors will affect the overall health of your

battery: the environmental temperature and the percentage of charge on the battery when it’s

powered down for storage. Therefore, we recommend the following:

• Do not fully charge or fully discharge your device’s battery — charge it to around 50%. If

you store a device when its battery is fully discharged, the battery could fall into a deep

discharge state, which renders it incapable of holding a charge -a deep discharged

battery must not be recharged for safety reasons, so it should be replaced and disposed

properly. Conversely, if you store it fully charged for an extended period, the battery may

lose some capacity, leading to shorter battery life.

• Be sure to turn off the device to avoid additional battery use. To turn off the device

completely, use the power switch and not the automatic power off function. The device

uses some battery power during the automatic power-off state, so the battery can be

completely discharged if the device is left in this state for a prolonged period.

• Place your device in a cool, moisture-free environment that’s less than 32° C (90° F).

• If you plan to store your device for longer than six months, charge it to 50% every six

months.

3) Replace the battery when necessary

The typical estimated life of a Lithium-Ion battery is about two to three years or 300 to 500

charge cycles, whichever occurs first. One charge cycle is a period of use from fully charged, to

fully discharged, and fully recharged again. Use a two to three-year life expectancy for batteries

that do not run through complete charge cycles.

Consider replacing the battery with a new one if you note that the battery run time drops below

about 80% of the original run time. Also, deep discharged batteries must be replaced for safety

reasons.

4) Properly dispose the battery

Lithium-Ion batteries are subject to disposal and recycling regulations that vary by country and

region. Always check and follow your applicable regulations before disposing of any battery.

Many countries prohibit the disposal of waste electronic equipment in standard waste

receptacles.
