Battery and Charger
Unplug the charger from the electrical plug and the device when not in use.
The battery can be charged and discharged hundreds of times before it
eventually wears out. When the standby time and the talk time are shorter
than the normal time, replace the battery.
Use the AC power supply defined in the specifications of the charger. An
improper power voltage may cause a fire or a malfunction of the charger.
Do not connect two poles of the battery with conductors, such as metal
materials, keys, or jewelries. Otherwise, the battery may be short-circuited and
may cause injuries and burns on your body.
Do not disassemble the battery or solder the battery poles. Otherwise, it may
lead to electrolyte leakage, overheating, fire, or explosion.
If battery electrolyte leaks out, ensure that the electrolyte does not touch your
skin and eyes. When the electrolyte touches your skin or splashes into your
eyes, wash your eyes with clean water immediately and consult a doctor.
If there is a case of battery deformation, color change, or abnormal heating
while you charge or store the battery, remove the battery immediately and stop
using it. Otherwise, it may lead to battery leakage, overheating, explosion, or
fire.
If the power cable is damaged (for example, the cord is exposed or broken), or
the plug loosens, stop using the cable at once. Otherwise, it may lead to an
electric shock, a short circuit of the charger, or a fire.
Do not dispose of batteries in fire as they may explode. Batteries may also
explode if damaged.
Danger of explosion if battery is incorrectly replaced. Recycle or dispose of
used batteries according to the local regulations or reference instruction
