1.2 Precaution before using battery
1.
Do not leave the battery unused for long time, no matter if it is in the device or inventory. If the
battery has been used for 6 months, it should be checked for its charging function or it should
be disposed correctly.
2.
The lifespan of Li-ion battery is around 2 to 3 years and can be circularly charged from 300 up to
500 times (one full battery charging period means it’s completely charged and completely
discharged).
3.
When the Li-ion battery is not in use, it will continue discharge slowly. Therefore, battery
charging status should be checked frequently and reference of the related battery charging
information on the manuals should be taken.
4.
Observe and record the information of a newly unused and non-fully charged battery, based on
the operating time of the new battery, and compare it with a battery that has been used for a
long time. According to product configuration and application program, the operating time of
battery would be different.
5.
Check the battery charging status at regular intervals.
6.
When the battery operating time drops below about 80%, charging time will be increased
remarkably.
7.
If a battery is stored or otherwise unused for an extended period, be sure to follow the storage
instructions in this document. If you do not follow the instructions, and the battery has no
charge remaining when you check it, consider it to be damaged. Do not attempt to recharge it or
to use it, and instead replace it with a new battery.
8.
Store the battery at temperatures between 5 °C and 20 °C (41 °F and 68 °F).
