Abstract: An adaptable battery tray for supporting a battery includes a body having a pair of end walls and side walls, with each end wall rotatably attached to an adapter. The adapter is rotatable between a first position and a second position. In the first position, the adapters are external to the interior of the battery tray and permits the battery tray to support a battery having dimensions approximating the dimensions between the side walls and the end walls. When a battery of lesser length is to be supported, the adapters are rotated into the second position, and include a pair of stop plates which define therebetween a wall suitable for housing the battery of lesser dimensions.
