Lead acid batteries for energy storage must have the following characteristics
1. The temperature range used is relatively wide, generally requiring normal operation in a temperature environment of -30-60 degrees.
2. The low-temperature performance of batteries is good, and they can be used even in areas with relatively low temperatures.
3. Good consistency in capacity, maintaining consistency in both series and parallel use of batteries.
4. Good charging acceptance ability. In unstable charging environments, there is a stronger ability to accept charging.
5. Long lifespan, reduced maintenance and repair costs, and overall system investment.
