ABSTRACT:
A battery separator for use in flooded cell type lead acid batteries comprising a backweb of a porous, acid resistant, embossable material with a plurality of major ribs and submini-ribs extending across the width of the backweb from at least one planar surface of the backweb. The submini-ribs extend in a direction substantially parallel to the longitudinal axis of the backweb. The major ribs extend in a direction that is diagonal to the longitudinal axis of the backweb. Each major rib is an embossed corrugated structure comprised of alternating ridges and furrows. The separator is particularly useful in a flooded cell type lead acid battery having tubular plates.
