A tray device having a predetermined rectangular shape for holding a battery conforming to the predetermined rectangular shape comprising a front panel, a rear panel and a pair of side panels forming the predetermined rectangular shape. The side panels each have bottom panels folded to form a bottom for the predetermined rectangular shape. The bottom panels also have bottom flanges and the side panels each have side flanges with all of the flanges being folded a right angles to their respective panels to provide parallel contact with the front and rear panels. The side flanges have sufficient space from the bottom flanges to permit location of all of the flanges in one plane of contact with the front and rear panels. The tray is assembled using a plurality of spot welds fixedly attaching the flanges to the front and rear panels without substantially altering the predetermined rectangular shape.
