Claim:
1. 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, the bottom frame element having a first margin, the top frame element having a lug, and a plurality of interconnecting electrically conductive grid elements defining a grid pattern defining a plurality of open areas; a plate of a second polarity opposite the first polarity and formed by an electrically conductive grid body having opposed top and bottom frame elements, the bottom frame element having a second margin, the top frame element having a lug, and a plurality of interconnecting electrically conductive grid elements defining a grid pattern defining a plurality of open areas; a highly absorbent separator wrapped around at least a portion of the plate of a first polarity and extending to opposing plate faces, wherein the separator is wrapped around bottom frame element of the plate of a first polarity such that the separator extends upwardly along the opposing plate faces toward the lug, and wherein the lug of the plate of a second polarity is aligned with the lug of the plate of a first polarity wrapped with the separator, and wherein a height of the plate of a first polarity differs from a height of the plate of a second polarity.
