ABSTRACT:
A valve-regulated lead acid (VRLA) battery cell (2,40) has positive and negative plates (10,11,41,42) separated by separator media (12,43) and held together under pressure. The separator is adapted to support therein an electrolyte. Each plate has a first single or plurality of tabs (12,13,46) on a first side and a second single or plurality of tabs (15,16,47) on a second side of the plate, each tab being connected to a busbar (17,18,49,50) to form positive and negative busbars on each of the first and second sides of the plate. The cell may be alternatively configured in a spirally-wound arrangement or in a prismatic arrangement of flat plates. The cell may be constructed of a plurality of such positive and negative plates. A VLRA battery (1, 40) may be constructed of one or a plurality of such VLRA cells, in which case the busbars of neighboring cells are connected by welded joints. The busbars are serviced by at least plural pairs of positive and negative terminals (24,25,33,34,52,53,54,55).
