280Ah Battery Performance Analysis

280Ah Battery Performance Analysis

  280Ah batteries are a critical component in portable electronic devices, and their cycle and calendar life significantly impact device reliability and user experience. The following is a concise analysis based on recent test data.

## Cycle Life

Cycle life is a measure of a battery's ability to retain capacity over repeated charge and discharge cycles. Our testing was performed at 25°C and 45°C.

- At 25°C, the battery retained 95.74% of its capacity after 500 cycles and 85.36% after 4100 cycles.

- At 45°C, retention was slightly lower, with 92.67% after 500 cycles and 77.49% after 3680 cycles.

## Calendar Life

Calendar life refers to the decay of a battery's capacity over time when not in use. The 280Ah battery shows a consistent capacity drop at both 25°C and 45°C, with the drop being more pronounced at higher temperatures.

## Conclusion

The 280Ah battery performs well under standard conditions, with cycle life and calendar life being affected by temperature. For optimal performance, operating temperature must be managed to extend the useful life of the battery. This analysis is critical for manufacturers and users to make informed decisions regarding battery usage and device design.
