1. A multi-cell Pb-acid storage battery comprising:

  • an open-ended case including a plurality of external walls defining a central cavity;

    a plurality of partitions dividing said cavity into several compartments each adapted to receive a galvanic cell element immersed in electrolyte, said cell element comprising a stack of alternately interleafed positive and negative polarity plates, said plates each having a lug projecting therefrom for electrically coupling the plate to other plates in the same cell element and to an adjacent cell element via an intercell connector;

    a cover sealed along its borders to said external walls and including a closure wall substantially completely overlying said open-end such as to substantially confine said electrolyte to said compartments;

    an undivided recess in said cover, said recess traversing said several compartments and defined in part by said closure wall;

    a terminal post on each element for concentrating the current flowing to and from a plurality of like-polarity plates in said element, said post projecting from a bundle of lugs from like-polarity plates through said closure wall and into said recess;

    a plurality of apertures in said closure wall and through which said posts project into said recess from said elements;

    seal means engaging said post and said closure wall at each said aperture for preventing passage of said electrolyte from said compartment into said recess through said aperture;

    a discrete intercell connector manifold in said recess adjacent said closure wall and traversing said several compartments, said manifold comprising a non-conductive carrier plate including as an integral part thereof a plurality of small, highly conductive links of lightweight, electrolyte-destructible metal and serving to permit en masse handling of said links and electrical coupling of the terminal posts of several different cell elements together into a plurality of sets according to a desired interconnection pattern;

    at least two openings in each said link, each said opening mating with and secured to a said post; and

    means for protectively covering said manifold.
