Patent ID: 8586248

Claim:
A battery plate assembly for a lead-acid battery comprising: a plate of a first polarity formed by an electrically conductive grid body having opposed top and bottom frame elements and opposed first and second side frame elements provided about a plurality of interconnecting electrically conductive grid elements defining a grid pattern having a plurality of open areas, the grid elements including a plurality of radially extending vertical grid wire elements originating from the top frame element, and a plurality of horizontally extending grid wire elements extending between the side frame elements, the bottom frame element having a first margin, and the top frame element having a first lug; and a plate of a second polarity opposite the first polarity formed by an electrically conductive grid body having opposed top and bottom frame elements and opposed first and second side frame elements provided about a plurality of interconnecting electrically conductive grid elements defining a grid pattern having a plurality of open areas, the grid elements including a plurality of radially extending vertical grid wire elements originating from the top frame element, and a plurality of horizontally extending grid wire elements extending between the side frame elements, the bottom frame element having a second margin, and the top frame element having a second lug, wherein the second margin is greater than the first margin such that when the plate of a first polarity is wrapped with a separator, the first lug is aligned with the second lug.
