Abstract
A battery comprises a single flat cell with a cell casing in the form of a plastic cup, or several cells piled on each other, whereby the plastic cups are integrally connected along the circumference. Each plastic cup comprises a terminal plate located both on the inner side and on the outer side of the bottom of each cup. One of these terminal plates comprises a projecting knob extending through an aperture in the bottom of the cup, and is connected to the other terminal plate in such a manner that the plates squeeze tightly about the bottom of the cup and abut the upper and lower surfaces thereof by a permanent pressure. As a result, a durable, efficient sealing against electrolyte leakage at the terminal passage in the bottom of each plastic cup is provided.
