Abstract
A receptacle for retaining a battery case in a battery powered vehicle contains hydraulic cylinders for lowering and raising the battery case into and out of the vehicle. Retaining arms attached to the hydraulic cylinder have retaining lips that are moved by contact with the walls of the receptacle to engage lip extensions on the battery case when the battery case is loaded into the vehicle. Upon removal of the battery case a bias spring swings the retaining arms away from the battery and releases it for removal.
