Important Questions on Batteries
The type of cell in a lead storage battery is:

During the discharge of a lead storage battery, the density of sulphuric acid fell from 1.294 to 1.139 Sulphuric acid of density 1.294 by weight and that of 1.139 by weight. The battery holds 3.5 litres of the acid and the volume remained practically constant during the discharge.
