Battery

The battery is rechargeable up to hundreds of times, but its
capacity will reduce. You may need to replace a new battery
when the operation duration (calling and standing duration)
reduces evidently.
Remove charger from the source each time after charging.
Over charging will shorten the life of the battery. Avoid
charging a battery for over 24 consecutive hours.
Use only batteries certified by the mobile phone
manufacturer.
Extreme temperatures will affect charging performance. The
desirable ambient temperature for charging is 0°C-45°C
(32°F-113°F).
Do not use damaged or old batteries.
Avoid contacts of the positive and negative poles of the
battery with metals, such as coins, scissors, and pens. It will
damage or cause short circuit to the battery. Place spare
batteries in a safe place or wrap them up with insulated
materials before putting inside your pocket or handbags.
Extreme temperatures will reduce the capacity or shorten the
life of batteries. Avoid placing batteries in extreme
temperatures, such as inside vehicles or near air-conditioner
outlets. The desirable battery storage temperature is
15°C-25°C (59°F-77°F). Batteries that have been charged
may not work properly in extreme temperatures.
Keep batteries away from water or fire.
Dispose batteries according to local environmental
regulations.
