Precaution before using battery

• Do not leave the battery unused for long periods. If a battery has been used for 6 months, check its charging function or dispose of it correctly.
• The lifespan of a Li-ion battery is around 2 to 3 years, with a charge cycle of 300 to 500 times (one full charge period means completely charged and completely discharged).
• When not in use, Li-ion batteries will continue to discharge slowly. Check battery status frequently.
• Observe and record the operating time of new and used batteries to compare performance. Operating time may vary based on product configuration and application.
• Check battery charging status at regular intervals. Charging time may increase when battery operating time drops below 80%.
• If a battery is stored for an extended period, follow the storage instructions. Failure to do so may result in damage, and the battery should not be recharged or used. Replace with a new battery.
• Store the battery at temperatures between 5 °C and 20 °C (41 °F and 68 °F).

Charger

The charger type is GME10D-050200FGu, with an output voltage/current of 5V DC/2A. The plug serves as the disconnect device of the adapter.
