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).

We claim: 1. A battery cell comprising: a positive and negative plate cooperatively wound in a spiral assembly and a separator providing separation therebetween, each plate having a first side thereof and a second side thereof; first positive and negative busbars connected up with the first sides of the positive and negative plates, respectively, and second positive and negative busbars connected up with the second sides of the positive and negative plates, respectively; a sealed case therefor which extends between spaced first and second ends; and, first positive and negative terminals being arranged to protrude from the first end of the case and connected to the first positive and negative busbars, respectively, and second positive and negative terminals being arranged to protrude from the second end of the case and connected to the second positive and negative busbars, respectively, whereby said terminals are distributed to better service the thermal extraction of the current-resistive heating effects induced by the plates and/or busbars and eliminate relative hot-spots from developing in any under-served regions. 2. The cell of claim 1 further comprising each plate having a first plurality of loci on the first side of the plate, and a second plurality of loci on the second side of the plate, wherein each first and second positive and negative terminal is connected up with the corresponding plurality of loci of the first or second sides of the positive or negative plates, respectively. 3. A battery comprising at least two cells according to claim 1. 4. A battery cell comprising: a positive and negative plate cooperatively wound in a spiral assembly and a separator providing separation therebetween, each plate having a first side thereof and a second side thereof; a first positive conductor connected up with the first side of the positive plate and adapted for serving a positive terminal; a first negative conductor connected up with the first side of the negative plate and adapted for serving a negative terminal; a second positive conductor connected up with the second side of the positive plate and adapted for serving a positive terminal; a second negative conductor connected up with the second side of the negative plate and adapted for serving a negative terminal; a sealed case therefor which extends between spaced first and second ends; and, first positive and negative terminals being arranged to protrude from the first end of the case and connected to the first positive and negative conductors, respectively, and second positive and negative terminals being arranged to protrude from the second end of the case and connected to the second positive and negative conductors, respectively, whereby said terminals are distributed to better service the thermal extraction of the current-resistive heating effects induced by the plates and/or conductors and eliminate relative hot-spots from developing in any under-served regions. 5. The cell of claim 4 further comprising each plate having a first plurality of loci on the first side of the plate, and a second plurality of loci on the second side of the plate, wherein each first and second positive and negative terminal is connected up with the corresponding plurality of loci of the first or second sides of the positive or negative plates, respectively. 6. A battery comprising at least two cells according to claim 4. 7. The cell of claim 4 wherein: the first positive conductor is connected up with the first side of the positive plate at a plurality of spaced locations; the first negative conductor connected up with the first side of the negative plate at a plurality of spaced locations; the second positive conductor connected up with the second side of the positive plate at a plurality of spaced locations; and the second negative conductor connected up with the second side of the negative plate at a plurality of spaced locations.
