LiPO Batteries Applications
1)Polymer lithium batteries are used in a wide range of
applications, including wearable devices, electric toys and smart
devices.
2)POS Machine, speakers, GPS tracker and all possible electronics
products
3)Widely applied in telecommunications, audio and video devices,
information devices, etc.
Precautions for Use
1. Charging: Use a charger designed for polymer lithium batteries.
Avoid overcharging.
2. Discharging: Prevent deep discharge by avoiding extremely low
voltage levels. Most polymer lithium batteries have built-in
protection circuits.
3. Temperature: Operate within the recommended temperature range
provided by the manufacturer. Avoid exposing to extreme
temperatures.
4. Physical Handling: Handle with care to avoid damage or leakage.
Avoid impacts, punctures, or bending.
5. Compatibility: Ensure compatibility with your device in terms of
voltage, capacity, and size.
6. Storage: Store in a cool, dry place away from direct sunlight.
Avoid storing at full charge or completely discharged.
7. Transportation: Comply with transportation regulations and
guidelines.
8. Disposal: Dispose of properly. Recycle at designated facilities
or follow local regulations.
