Abstract: A portable cart-supported battery charger includes a tubular framework having a L-shaped lower portion that forms a cradle for elevating the housing that is supported thereon, and a u-shaped handle detachably securable to the L-shaped lower portion, and the L-shaped lower portion having a pair of wheels so that the battery charger is portable. A pair of handle knobs secures the handle to the L-shaped lower portion, and loosening the handle knobs allows for the removal of the handle from the L-shaped lower portion while tightening the handle knobs secures the handle to the L-shaped lower portion. One battery cable holder projects from the handle and one cable holder projects from the L-shaped lower portion for supporting the battery cables and clamps. The host battery and the AC charger are contained within the housing, and gauges on the front panel of the housing are easily viewable to the user because of the position of the housing on the framework of the battery charger.
