The first use of the new battery
The first use of the new battery, the battery comes out of the factory with the use of electricity, and then charge 2-4 hours, pay attention not to charge, so as to avoid damage to the lithium-ion batteries, the impact of service life. After the 2-3 times, the electric core is fully activated and the standby mode is entered into the best state. After each full.
Inferior charger will affect the standby time and shorten the battery life.
Please don\'t charge the battery for a long time, the general full complement 1 hours or so, the use of the best.
In extreme cases, an improper charge can destroy a battery.
Recommend the use of original charger or performance of the charger to charge the battery.


Several effects on standby
1. The weaker the signal, the greater the power consumption, the shorter the standby time.
2. Environmental temperature is too high or too low, the standby time is short.
3. Refurbished machines, the revision machine, power consumption is likely to be large, the standby time may be short.
4. Charging time is too long. The battery is charged, the battery will generate a virtual power, but will be short of standby time.
5. Charger does not pass. Standby time is short.
6. to listen to music, Internet, etc., power consumption, standby time is short.

Package: 1 battery without retail box

(some battery may do not put yellow tape as the picture. but does not effect anything)
