New or improved lead acid batteries with vapor pressure barriers and/or improved battery separators, as well as systems, vehicles, and/or methods of manufacture and/or use thereof are disclosed herein. In at least select embodiments, the instant disclosure provides new or improved lead acid batteries with a vapor pressure barrier. In at least select embodiments, the instant disclosure provides new or improved lead acid battery vapor pressure barriers along with new or improved battery separators, and/or methods of manufacture and/or use thereof. In at least select embodiments, the instant disclosure provides a new or improved lead acid battery with a vapor pressure barrier that reduces the water loss from the battery. In at least select embodiments, a method of reducing the water loss of a lead acid battery may include providing a vapor pressure barrier, such as a layer of oil, inside the lead acid battery along with an improved battery separator.

Vapor pressure barriers for lead acid batteries for improved water loss performance, separators, systems, and methods of manufacture and use thereof

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.
