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.
