In most cases, a single cell does not provide a high enough voltage and a serial connection of several cells is needed. The metallic skin of the cell is insulated to prevent the 'hot' metal cylinders from creating an electrical short circuit against the neighboring cell.
Nickel-based cells provide a nominal cell voltage of 1.25V. A lead acid cell delivers 2V and most
