Value regulated lead acid battery

A plural-cell valve-regulated lead acid battery having cells of flat plural-tab plates, comprising:

• a plurality of cells, each having an axially layered plurality of charged and oppositely-charged flat plural-tab plates, another plurality of separator media interleaved between at least that much of the flat plates generally exclusive of any tabs, and axially extending busbars arranged traversing the layers;
• a sealed case for supporting the plurality of cells in an axial row and with the plates thereof upright in generally vertical planes, and including sufficient cell partitions for separating adjacent cells;
• each upright plate having, exclusive of the tabs, spaced side edges extending between a spaced top and bottom edge, and further having top and bottom tabs protruding from the respective top and bottom edges and co-planar with the rest of the flat plate;
• the busbars of each cell including parallel charged and oppositely-charged upper busbars disposed across the top edges of the layered plates and connected with the top tabs of the charged and oppositely-charged plates respectively, as well as parallel charged and oppositely-charged lower busbars disposed under the bottom edges of the layered plates and connected with the bottom tabs of the charged and oppositely-charged plates respectively;
• a multiplicity of partition-traversing links such that each busbar is adapted for connecting in series by a respective partition-traversing link with an in-row axially-aligned busbar of alternate charge belonging to an adjacent cell in an adjacent compartment wherein said respective link traverses the respective interposed cell partition;
• and
• terminals, which protrude externally of the case, being connected inside the case to given ones of the busbars wherein the terminals include charged and oppositely-charged upper terminals connected to at least one charged and oppositely-charged upper busbar respectively as well as include charged and oppositely-charged lower terminals connected to at least one charged and oppositely-charged lower busbar respectively such that thermal transmission of current-resistive heating effects from the plates is conducted by the upper and lower parallel series of busbars to destinations externally from the case through the upper and lower charged and oppositely-charged terminals, concurrently, in order to eliminate or substantially reduce thermal gradients especially cooler lower regions, and thus achieve more even temperatures throughout said cells and said battery, which correspondingly eliminates or substantially reduces various deleterious consequences including preferential sulphation in cooler regions.
