Abstract A battery retention system which is intended to support a conventional type of automobile battery in its rack in an automobile or truck. The retention system is made up of spaced lugs integrally attached to two opposite sides or ends by the battery case. A holddown rod is attached to each of two opposite sides of the battery rack. The lugs are spaced apart just enough to freely receive the bolts between them. Each lug has an indentation, and a rubber washer is received on each bolt. A metal washer is supported on the top of the rubber washer and the rubber washer is deformed into the notch in the lugs so that the holddown rod will not slip relative to the case. The insulation characteristics of the rubber prevents leakage of electrical current from the battery to the battery case.
A battery holddown device comprising a battery, said battery having a case supported on a battery rack, said battery case having laterally spaced lugs at each end or each side and said spaced lugs being integrally attached to said case, a washer having substantially the same properties of resiliency as rubber overlying each pair of said lugs, a bolt engaging each end or each side of said battery rack and extending upward between said lugs and through said washers and a nut on said bolt clamping said washers and said battery in place, said lugs having an indented surface on their upper side, said indent slopes outwardly and downwardly and terminates in a generally vertical inwardly facing shoulder, said rubber washer is compressed by said nut and thereby deformed to conform to the shape of said indent, thus locking said rod in firm position, said battery case has a recess adjacent each pair of said lugs, a sheet of material overlying said battery and terminating in said recess, said rubber washer overlying said sheet and holding said sheet in place.
