Abstract: An apparatus for holding a battery of a vehicle. A mounting frame is attached to a vertical surface of the vehicle and supports a detachable box in which the battery is retained. A pair of slide members on the mounting frame are slidably receivable within a corresponding pair of guide members on the box so as to permit vertical slidable adjustment of the box relative to the mounting frame. The box may be held in either a transport or an access position by a latching mechanism consisting of a pair of hooks attached to the box and a pair of channels on the mounting frame. A pair of perforations in the channels receive the hooks and define the transport and access positions of the box.
