Abstract

A battery plate assembly for a lead-acid battery is disclosed. The assembly includes a plates of opposing polarity each formed by an electrically conductive grid body having opposed top and bottom frame elements and opposed first and second side frame elements, the top frame element having a lug and an opposing enlarged conductive section extending toward the bottom frame element; a plurality of interconnecting electrically conductive grid elements defining a grid pattern defining a plurality of open areas, the grid elements including a plurality of radially extending vertical grid wire elements connected to the top frame element, and a plurality of horizontally extending grid wire elements, the grid body having an active material provided thereon. A highly absorbent separator is wrapped around at least a portion of the plate of a first polarity and extends to opposing plate faces. An electrolyte is provided, wherein substantially all of the electrolyte is absorbed by the separator or active material. A method for assembling a battery is also disclosed.

First claim
