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.

A stamped grid for a lead-acid battery having a grid pattern that is optimized for electrical performance. The stamped grid includes an electrically conductive grid body having opposed top and bottom frame elements, opposed first and second side frame elements and a plurality of interconnecting grid wire elements forming a grid pattern. The grid wire elements include a plurality of vertical wire elements connected to both top and bottom frame elements, a plurality of vertical wire elements connected to the top frame element and one of either the first or second side frame elements and a plurality of cross grid elements that interconnect the vertical wire elements. Each of the vertical grid elements that is connected to the top frame element and one of either the first or second side frame elements includes a plurality of the cross frame elements connected thereto at a substantially 90° angle. Optionally, the cross grid elements in the middle portion of the grid are arranged in an offset or staggered relationship. The vertical grid elements and the cross frame elements define open areas for supporting electrochemical paste where most of the open areas are within the two percent of being the same size.

An grid for a lead acid battery plate includes a central plate lug, the lug preferably having an expanded base for the collection of current and the grid being constructed in such a manner that the amount of metal is concentrated in the vicinity of the lug. A unique cast-on strap design for use with the grids is also disclosed. Substantial manufacturing advantages result from the use of such grids, and the performance of the battery can be increased to the point that individual battery plates may be eliminated, resulting in lighter weight batteries and material cost savings.

The invention provides a vehicle battery system including a main and a reserve battery disposed within a battery housing (10) having conventional external dimensions and battery terminal locations. An illustrated embodiment includes a main battery, comprising a series of thin, flat cells (38) disposed along a first axis, and a reserve battery, comprising a series of cells (42) diposed along a second axis transverse to the first axis. An electrical circuit facilitates selective communication between the reserve battery and the vehicle starter in accordance with the position of a switch assembly (100). The circuit illustratively includes a diode (110) configured to permit current flow into the reserve battery (104) during recharging, but which prevents reserve battery drain during normal vehicle operation. A variable resistor (112) is disposed in series with the diode to limit the amount of power, and hence the amount of heat, dissipated by the diode. When the main battery becomes drained, switch assembly (100) is actuated to bring the reserve battery (104) into parallel with the main battery (102).
