4. Battery information
Your device is powered by a rechargeable battery. The full
performance of a new battery is achieved only after two or three
complete charge and discharge cycles. The battery can be charged
and discharged hundreds of times, but it will eventually wear out.
Recharge your battery only with compatible chargers designated for
this device.
Unplug the charger from the electrical plug and the device when not
in use. Do not leave a fully charged battery connected to a charger,
since overcharging may shorten its lifetime. If left unused, a fully
charged battery will lose its charge over time.
Never use any charger that is damaged.
Leaving the device in hot or cold places, such as in a closed car in
summer or winter conditions, will reduce the capacity and lifetime of
the battery. Always try to keep the battery between 15
℃
and 25
℃
(5
9
℉
and 77
℉
). A device with a hot or cold battery may not work
temporarily, even when the battery is fully charged. Battery
performance is particularly limited in temperatures well below
freezing.
Do not dispose of batteries in a fire as they may explode. Batteries
may also explode if damaged. Dispose of batteries according to local
regulations. Please recycle when possible. Do not dispose as
household waste.
