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 talk time are shorter than normal, replace the battery.
Use the AC power supply defined in the specifications of the
charger. An improper power voltage may cause fire or the
charger may not function properly.
If the ambient temperature is considerably low or high, the
capacity and life of the battery is reduced. When the
temperature is lower than 0°C, performance of the battery is
affected.
Do not connect two poles of the battery with conductors
such as metal materials, keys or jewelries. Otherwise, the
battery may be short-circuiting 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, make sure 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 the battery is damaged, or the color changes or gets
abnormally heated 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.
