3.7V 250mAh Rechargeable Lithium Polymer Battery 502030 for Beauty Devices
Rechargeable Lithium Polymer Battery Features
1. The self-discharge is small, and the capacity loss is small after a long time.
2. Long life, the normal use of its cycle life can reach more than 500 times.
3. No memory effect, no need to empty the remaining power before charging, easy to use.
4. Good security
Polymer lithium battery in the structure of aluminum-plastic flexible packaging, different from the metal shell of the liquid battery, once a safety hazard, liquid battery is prone to explosion, but the polymer battery will only gas drum.
5. Light weight
The weight of the polymer battery is 40% lighter than that of the lithium battery of the same capacity, and 20% lighter than that of the aluminum battery.

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.
