An electric storage battery assembly is formed of easily removable individual cell casing units. Each of the cell units is provided on alternate corner edges with vertical dovetail projecting ribs and dovetail grooves. The dovetail ribs and grooves provided on the edges of adjacent cell casings matingly and removably interengage. Conductor straps are provided to removably mechanically and electrically interconnect the electrode terminal posts of adjacent cell units in series arrangement. Longitudinal U-shaped channeled covers may be provided to slidably interlock with the conductor straps connecting adjacent cell casings. A cell casing lid provided with suitable openings and electrolyte-filling bosses is provided to cover and close the open top end of the cell casing. The lid may be provided on one side with a horizontal locking sleeve which removably interengages with a slidable transverse lug provided with a correspondingly shaped dovetail recess which matingly receives the dovetail shaped locking sleeve formed on the lid. This construction permits ready removal and replacement of defective cell units as well as flexibility in providing desired dimension configuration and electric output rating in the composite battery assembly by manufacturers, jobbers or distributors.
