A battery compartment is supported on the frame apparatus of a child's swing at a location that is remote from the electric motor powering the operative movement of the seat assembly. The battery compartment is located within a mounting housing mounted on a rear leg of the frame assembly where a corresponding front leg is detachably connected to the rear leg. The battery array housed in the battery compartment is connected to the remote electric motor by wiring positioned within the interior of the rear leg interconnecting the mounting housing in which the battery compartment is located and the housing in which the electric motor is located. The battery compartment is positioned below the top surface of the seat member in which an infant would be positioned and rearwardly of the seat member due to the curved configuration of the rear legs of the frame assembly.
