Abstract

A housing for batteries which may be combined with a battery charger in a mechanically integrated module. The module is mobile and includes a load-bearing frame, battery retaining members, and mechanical stabilizers. The base of the frame includes a raceway or channel for routing interconnecting wires between the charger assembly and batteries. The battery retaining members permit easy installation or removal of individual batteries from the housing as well as inhibiting lateral movement of the batteries within the housing. When the module is free-standing, the stabilizers deploy automatically for enhanced mechanical stability.
