The lead accumulator has stable working voltage, wide range of using temperature and current, several hundred cycles of charging and discharging, good storage performance (especially suitable for dry charge storage) and low cost, so it has wide application. At present, the lead storage battery is widely applied to the fields of automobiles, trains, tractors, motorcycles, electric vehicles, communication, power stations, power transmission, instruments and meters, UPS power supplies, airplanes, tanks, naval vessels, radar systems and the like. With the development of world energy economy and the increasing improvement of people's living standard, lead storage batteries have occupied more than 85% of market share in secondary power supply use.
