Disclosed herein are exemplary embodiments of improved electrode plate and separator assemblies () for lead acid batteries, improved lead acid cells or batteries incorporating the improved assemblies, systems or vehicles incorporating the improved assemblies () and/or batteries (), and methods related thereto. The electrode plate () may have a grid () of a stamped, cast, or expanded metal manufacturing process. The grid () may have a non-uniform application of active material (). The separators () preferably provide a support structure for resisting or mitigating any plate warping or plate deflection.

Lead acid battery separators, warp resistant separators, batteries, systems, and related methods

In accordance with at least selected embodiments, the present disclosure or invention is directed to improved battery separators, high conductance separators, improved lead-acid batteries, such as flooded lead-acid batteries, high conductance batteries, improved systems, and/or, improved vehicles including such batteries, and/or methods of manufacture or use of such separators or batteries, and/or combinations thereof. In accordance with at least certain embodiments, the present disclosure or invention is directed to improved lead acid batteries incorporating the improved separators and which exhibit increased conductance. Particular, non-limiting examples may include lead acid battery separators having structure or features designed to improve conductance, lower ER, lower water loss, and the like.
