Product Features


1. Environmental Friendly: This lithium battery not only provides efficient power storage but also contributes to environmental sustainability. By avoiding the use of hazardous materials like lead or mercury, it minimizes harm to the ecosystem during manufacturing, usage, and disposal.

2. High Energy Density: Despite its compact size, this battery boasts a high energy density, allowing it to store a considerable amount of energy. This characteristic is particularly advantageous for applications with limited space, such as solar street lights, where maximizing energy storage in a small footprint is crucial.

3. Lightweight: Its lightweight design makes handling and installation hassle-free, reducing labor costs and easing logistical challenges during deployment. This feature is especially beneficial for portable or mobile applications, where weight considerations are paramount.

4. Low Self-Discharge: The battery's low self-discharge rate ensures that stored energy remains available over extended periods, minimizing the need for frequent recharging. This feature is essential for applications requiring reliable and continuous power supply, such as solar street lighting systems operating in low-light conditions.

5. Low Internal Resistance: With minimal internal resistance, the battery can efficiently deliver power when needed, optimizing energy transfer and reducing heat generation. This characteristic not only enhances overall system efficiency but also prolongs battery life by minimizing energy losses during charging and discharging cycles.

6. Long Cycle Life: The battery's extended cycle life, coupled with its ability to be charged up to 2000 times, ensures long-term reliability and durability. This feature is particularly valuable for solar street lighting applications, where consistent performance over numerous charging cycles is essential to maintain illumination levels and ensure safety in outdoor environments.
