How To Use:
1. If the battery is under long time improper use or maintenance, there will be oxidation on the sheetmetal. This will lead to the automaticly shutdown or hang up while making a phone call. So it is suggested to clean up the sheetmetal before use.    
2. Only after 3 to 5 times of full charge and discharge of a new battery, will the internal chemicals all be activated, thus to reach the best using effect.
3. Improper charging methods of inferior chargers will affect the standby time and shorten the bettery life.
4. Different phone has different power consumption and it will increase the power consumption if the phone is under the vibration mode, thus reduce the standby time.
5. If the phone is used under weaker signal, its power consumption will be larger, as well as the shorter standby time.
6. Power of the full charge batteries under the mothball status will gradually reduce and the power loses naturally.

NOTE:Our battery is sent out with little or no power,so please charge it for about 4 - 6 hours before using.
