The present disclosure relates to lead-acid batteries and the manufacture of lead-acid batteries containing acid pump devices to promote the circulation of electrolyte within the battery and/or battery cells to reduce acid stratification and improve battery performance. In various embodiments, battery cell components are assembled within an acid pump assembly that encloses the battery cell components on at least the bottom and ends. In various embodiments, at least a portion of the acid pumps may be integrally molded with or secured to various parts of the battery housing including the cover, side walls, and cell walls. In various embodiments; space for the acid pumps is created by varying the shape of the battery housing (e.g., the side walls or cell walls) and/or by modifying the shape, size, and or position of one or more of the battery electrodes or separators.

Secondary battery with improved destratification

A battery grid is provided having a frame having a top element, a bottom element, a first side element, and a second side element. A current collection lug is coupled to the top element. The battery grid includes a plurality of wires provided within the frame and defining a plurality of open areas. The plurality of wires includes a vertical grid wire continuously extending from the bottom element toward the top element, and a plurality of horizontal grid wires continuously extending from the first side element or second side element, wherein the vertical grid wire intersects the plurality of horizontal grid wires, but does not intersect the first side element, second side element; or top element.

Battery grid

A battery grid includes a frame that includes a top element, a bottom element, a first side element, and a second side element. The battery grid also includes a plurality of wires provided within the frame and defining a plurality of open areas and a current collection lug extending from the top element in a first direction. The battery grid further includes at least one feature provided in the battery grid that is configured to reduce the amount of growth of the battery grid in the first direction due to corrosion of the battery grid during the life of the battery grid.

A battery grid is provided having a frame that includes a top element, a bottom element, a first side element, and a second side element. A current collection lug is coupled to the top element. The battery grid includes a plurality of wires provided within the frame and defining a plurality of open areas. The plurality of wires includes a plurality of linear vertical wire members which extend from the top element toward the bottom element, first side element, or second side element. At least one of the linear vertical wire members includes a discontinuity terminating the linear vertical wire member before reaching the bottom element, first side element, or second side element, the discontinuity being defined by parallel horizontal wire members defining an open space.
