The lead acid battery is most commonly used in the power stations and substations because it has higher cell voltage and lower cost. The various parts of the lead acid battery are shown below. The container and the plates are the main part of the lead acid battery.
The lead acid storage battery is formed by dipping lead peroxide plate and sponge lead plate in dilute sulfuric acid. A load is connected externally between these plates. In diluted sulfuric acid the molecules of the acid split into positive hydrogen ions (H +) and negative sulfate ions (SO 4 − −).
As a lead-acid battery is charged in the reverse direction, the action described in the discharge is reversed. The lead sulphate (PbSO 4) is driven out and back into the electrolyte (H 2 SO 4). The return of acid to the electrolyte will reduce the sulphate in the plates and increase the specific gravity.
