A battery assembly ( 10 ) has a series of rectangular cells ( 20 ) and a square-U shaped tray ( 14 ) to support the cells ( 20 ) in series, with bottoms ( 24 ) coplanar and adjacent sides parallel. The tray ( 14 ) has spaced arms ( 43 ) for opposing the endmost ones of the series of cells ( 12 ) interconnected by a rigid web ( 41 ) that provides a generally flat seating surface for the cell bottoms ( 24 ). The web ( 41 ) has longitudinal tracks ( 49 ) which raise above the seating surface of the wen ( 41 ) and which extend beneath all the cell bottoms ( 24 ). The cell bottoms ( 24 ) have counterpart longitudinal channels ( 52 ) for self-assembling with the tracks ( 49 ) of the web ( 41 ) and provide properly aligned seating of the cell bottoms ( 24 ) by disallowing lateral displacement but allowing longitudinal sliding order to form as dense as a single-file line-up ( 12 ) as possible. The tracks ( 49 ) also serve to stiffen the web ( 41 ) against sagging or twisting.
