A method of constructing a multi-cell storage battery comprises the following steps: molding a container of plastic in one piece with outer vertical container walls, an open bottom, longitudinally spaced transversely extending vertical cell partitions, and transversely spaced parallel channels extending longitudinally across the top of the container from and facing upwardly and outwardly of the container, the parallel channels being partially formed by upright spaced walls, the upper faces of the outer vertical container walls, the spaced upright walls defining the channels and the transversely extending partitions being coplanar, the channels having sections spanning adjacent cells and extending through the cell partition separating the adjacent cells; forming longitudinally spaced openings within the base of the channels for receiving plate lugs of the same polarity; inserting a plurality of battery plates through the open bottom of the container when the container is in an inverted position with the edges of the plates contacting the undersides of the channel base and with the lugs inserted within respective openings within the base of the channels; sealably coupling an imperforate bottom member to the open bottom of the container to locate fixedly the plates therein; electrically and mechanically coupling the lugs within channel sections together by at least melting the lugs within the channel sections to form strap connectors therein; and thermal welding a lid onto the container top at the coplanar upper faces of the upright walls defining the channels, the container walls, and the longitudinally spaced partitions to seal the strap connectors within the channel sections.
