If the internal fault of the battery leads to the existence of a conductor between the positive and negative plates, the battery will be short-circuited and the overall voltage will drop.
Positive Plate
The acid is doubly diluted at the positive plate, whereas at the negative only lead sulphate is formed. It is, consequently, necessary to provide a greater reservoir of acid adjacent to the positive plate, and in cells where the amount of acid is minimised it is usual to make separators with ribs which rest against the plate surface. Electrolyte
