The present invention provides, in one embodiment, a battery container. In this particular embodiment, the container comprises a housing having side walls and a spacing ridge formed in and extending outwardly from the side walls. The spacing ridge forms a groove on an interior surface of the walls and has a slot formed in the spacing ridge at first and second opposing ends of the housing. In an alternate embodiment, the spacing ridge has a plurality of slots formed on opposing ends of the container. Typically, two adjacent slots are formed on each end such that opposing ends of the handle may engage the retaining pin through the slots. The container further comprises a handle and a retaining pin configured to be received within the interior groove adjacent the slot. The handle is cooperatively engageable with the retaining pin to provide a lifting point for the container when the retaining pin is received in the interior groove. The handle and the retaining pin work cooperatively together to provide a handle that can easily be removed from the container, if so desired.

In a battery handle two bands of webbed material are each arranged and threaded to independently engage a plurality of slots at opposing ends of a support housing in which a battery is enclosed. Each end includes six slots arranged in pairs of slots. The longitudinal/major axis of the two uppermost slots are at an angle to the horizontal and the major axis of the remaining four slob are substantially horizontal. In another aspect, the band of webbed material is threaded through two or more slots and the ends are joined together. Another technique loops the ends and expands the loop with a mechanical insert to lock it to the support housing. Many variations of the invention will be readily apparent to those skilled in the art which do not depart form the spirit and scope of the invention.
