Detailed Solution

Lead storage battery consists of lead anode and a grid of lead packed with lead oxide $(P b O_{2})$ as cathode, a 38% solution of $H_{2} S O_{4}$ is used as an electrolyte. On charging the battery the reaction is reversed and $P b S O_{4} (s)$ on anode and cathode is converted into $P b$ and $P b O_{2}$ respectively.
