Modular, multicell lead-acid batteries

Abstract

A modular, multicell battery comprises a plurality of terminal frames, each of which is divided into a number of side-by-side active material support areas pasted with active material to form plates with adjacent plates in each frame being of opposite polarity and adjacent plates in adjoining frames also being of opposite polarity, each terminal frame also including frame positive and negative tabs, a plurality of floating frames similar to the configuration of the terminal frames but not including frame terminal tabs, electrolyte-porous separator frames positioned between adjacent plates in adjoining frames, at least one partition frame dividing the battery into at least two batteries, a positive busbar having a series of slots for accepting the frame positive tabs and electrically connected thereto, a negative busbar having a series of slots for accepting the frame negative tabs and electrically connected to such tabs, the assembly of frames being secured together and electrolyte fill holes for allowing each cell to be filled with electrolyte and a cover secured to the assembly of frames. In one embodiment of the invention, the cover includes venting means, the partition means includes apertures positioned above the electrolyte level of the battery and the positive busbar includes a switch actuator and a switch assembly allowing one or all parts of the battery to be placed in service, and the positive and negative busbars having the desired termination formed, as by die casting, thereon.
