1. A method of rebuilding a rechargeable battery comprising a set of spent, electrically interconnected, electrochemical cells of substantially uniform size within a battery case, the cells being connected to battery terminals on said battery case, each of said cells having a cylindrical shell, a positive terminal at one end of the shell, and a negative terminal at an opposite end of the shell, and said cells being arranged in an array in which the cylindrical shell of each cell is in close proximity to the cylindrical shell of at least one other cell in the array, and in which a first set of ends composed of one end of each of the shells is disposed substantially in a first plane and the remaining ends of the shells are disposed substantially in a second plane parallel to the first plane and spaced from the first plane by a distance substantially equal to the length of each of the shells, the method comprising the steps of:

  • removing said set of spent cells from the battery case;

    arranging a fresh set of cells in substantially the same arrangement as that of the spent cells, wherein each of a plurality of terminals of cells of the fresh set at the ends of the shells thereof in said first plane is permanently connected to one of a plurality of metal connecting parts before said fresh set of cells is arranged in said arrangement;

    establishing electrical interconnections in said fresh set of cells corresponding to the electrical interconnections in said set of spent cells, at least in part by connecting each of said metal connecting parts to another of said metal connecting parts by mechanically securing first and second parts of a conductive connector to respective metal connecting parts to be connected;

    enclosing the fresh set of cells within said battery case; and

    electrically connecting said fresh set of cells to said battery terminals on said battery case.
