ABSTRACT:
A battery separator is provided that has a plurality of protrusions extending above the main surface thereof. The protrusions are arranged in an entirely new pattern which permits a minimum total area of the separator to be covered with protrusions and yet assures good contact with all areas of a battery's grid. This is done by arranging the protrusions in alternating rows in a manner blocking any openings between protrusions with which an element of the battery's grid could be registered.
Another aspect includes a compressible battery separator having compressible embossments.
