ABSTRACT OF THE DISCLOSURE A common pressure vessel type Ni-H2 battery having a thermally conductive rack disposed within the pressure vessel and having an outer wall conforming to and in thermal contact with the inner surface of a cylindrical center wall portion of the pressure vessel and a plurality of fins dividing the rack into a plurality of compartments. A Ni-H2 battery cell is disposed in each of the compartments in thermal contact with adjacent ones of the fins. A plurality of flexure springs extend between racks, providing a radial force on the racks so as to urge the outer walls of the racks into contact with respective portions of the wall of the pressure vessel. A stopper is formed internally of the pressure vessel and a wave spring is disposed between a weld ring provided at the end of the rack opposite the stopper for forcing the racks in the longitudinal direction of the pressure vessel into contact with the stopper.
