Problems solved by technology

[0003] With the continuous development of wireless communication technology and the complexity of the application scenarios of wireless base stations, sometimes the temperature can reach above 60 ℃, which puts forward higher requirements for the high temperature performance, reliability and life of the battery; the existing communication market uses Ordinary valve-controlled sealed lead-acid batteries are low in cost and easy to maintain; however, when the ambient temperature is higher than 60°C, the float charge current will be large and the heat generated will increase, which will lead to a decrease in internal resistance and a further increase in float charge current , a vicious cycle, which eventually leads to the risk of thermal runaway; under high temperature conditions, grid corrosion speeds up, water loss increases, and battery life decreases rapidly
