4.35V Lithium Battery Advantages

The core technology of high voltage lipo battery is high voltage electrolyte system. Compared with traditional lithium-ion batteries, high voltage lipo battreies use a more stable and safer polymer electrolyte material, allowing the battery to operate at higher voltages. This high voltage electrolyte system can not only improve the energy density of the battery, but also reduce the internal resistance and energy loss of the battery, thereby improving the efficiency and cycle life of the battery.


4.35V Lithium Battery Application


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.
