A novel apparatus and method for constructing a stress resistant battery which allows the use low modulus materials through end wall rib reinforcements and a cover having a plurality of integral bosses which vertically project and connect to cast on straps. A plurality of baffles adapted to snap fit into the inner bottom portion of the cover and augment stress resistance through rigid contact against the battery plates. A plurality of cast on straps welded back to back in pairs through each of said electrochemical cell walls each having a seating boss so as to connect with each of the cover bosses. The battery of the present invention also includes means of affixing terminal connectors in a scalloped configuration thereby preventing over-torquing and failure of the cover during electrical-mechanical connection.

A stress resistant battery comprising: a casing having compartmental walls which partition a plurality of electrochemical cells each having a plurality of interleaved negative and positive plates; a cover having a top portion, a bottom portion and a perimeter, said bottom portion being adapted to fit into said casing, said cover further comprising a plurality of cover bosses integral with and protruding from said bottom portion of said cover; a plurality of baffles, said baffles being adapted to snap fit into said bottom portion of said cover so that when said cover is fitted to said casing an interference fit is made between said baffles and said electrochemical cells; a plurality of cast on straps welded back to back in pairs through each of said compartmental walls forming an electrical connection in series from one electrochemical cell to another electrochemical cell, each of said cast on straps further including a seating boss connecting with each of said cover bosses; a positive terminal connector having a substantially threaded elongate end and a platform attachment means on the other end, said platform attachment means welded to a positive plate group, said elongate end extending out of said cover to electrically connect to one side of a load; a negative terminal connector having a substantially threaded elongate end and a platform attachment means on the other end, said platform attachment means welded to a negative plate group, said elongate end extending out of said cover to electrically connect to the other side of a load.
