Abstract
Abstract A battery is provided, generally of the lead acid storage battery type, having spaced plates therein, with selected plates connected together in electrically conductive fashion, and with plates on opposite sides of cell partitions being connected, wherein particularly novel types and placements of such connections facilitate low resistance in connections between plates and preferably facilitate inclusion of greater quantities of acid within a battery, by effecting such connections externally of the battery casing.
