Abstract
In accordance with at least selected embodiments or aspects, the present invention is directed to improved, unique, and/or complex performance lead acid battery separators, such as improved flooded lead acid battery separators, batteries including such separators, methods of production, and/or methods of use. The preferred battery separator of the present invention addresses and optimizes multiple separator properties simultaneously. It is believed that the present invention is the first to recognize the need to address multiple separator properties simultaneously, the first to choose particular multiple separator property combinations, and the first to produce commercially viable multiple property battery separators, especially such a separator having negative cross ribs.
