3.2V280AH Lithium Battery

Performance characteristics

Energy density: Compared to traditional lead-acid batteries, it has a higher energy density and can store more electrical energy in a smaller volume and weight, making it suitable for use in devices that require weight and volume, such as portable energy storage devices.

Charge and discharge efficiency:

Charging efficiency: If charged at a charging rate of 0.3C-0.5C, it takes approximately 1.6-2.67 hours to fully charge. The loss of converting electrical energy into chemical energy during the charging process is relatively small.

Discharge efficiency: It can stably output current and high output power during discharge, and can provide continuous and stable power supply for various equipment. For example, when supplying power to small electric equipment, it can maintain stable voltage output until it approaches the discharge cut-off voltage.

Cycle life: Under appropriate charging and discharging conditions, the cycle life is relatively long, generally reaching 1000-3000 times or more. It has obvious advantages in long-term use scenarios such as energy storage systems, and can maintain a certain capacity for storing electrical energy for many years.

Self discharge rate: The self discharge rate is relatively low, and the monthly self discharge rate is usually around 3% -8% when stored at room temperature. After being fully charged and left for one month, the power loss is relatively small, and the storage performance is better than high self discharge rate batteries such as nickel cadmium batteries.
