Precaution before using battery

Do not leave the battery unused for a long time, no matter it is in the device or inventory. If the battery has been used for 6 months already, it should be checked for charging function or it should be disposed of correctly.
The lifespan of a Li-ion battery is around 2 to 3 years, it can be circularly charged 300 to 500 times. (One full battery charge period means completely charged and completely discharged.)
When the Li-ion battery is not in use, it will continue to discharge slowly. Therefore, battery charging status should be checked frequently and take reference related battery charging information on the manuals.
Observe and record the information of a new unused and non-fully charged battery. On the basis of the operating time of the new battery and compare with a battery that has been used for a long time. According to the product configuration and application program, the operating time of the battery would be different.
Check battery charging status at regular intervals.
When battery operating time drops below about 80%, charging time will be increased remarkably.
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. Replace it with a new battery.
Store the battery at temperatures between 5 °C and 20 °C (41 °F and 68 °F).
