ABSTRACT:
A method for manufacturing storage batteries including: molding plastic to integrally preform bottom and side walls and partitions to form first, last and at least two middle cells, the bottom wall having upwardly projecting ridges with upper edges below the electrolyte fill level forming positive and negative wells which extend to the partitions and are in alignment with the negative and positive wells, respectively, of the adjacent cells; placing an intercell connector across each partition below the fill level to be held by the case in position extending from one middle-cell well to a well in the adjacent cell; pouring molten lead into each well, the lead in each well of each middle cell engaging an intercell connector; inserting a cell group of plates into each cell, the plates having lower portions immersed in the molten lead in the wells before hardening; and closing the container by sealing a top wall to the side walls. This allows cells to be completely sealed from one another at positions below the fill level and each intercell connector to interconnect the lead in opposite-polarity wells of adjacent cells.
