Abstract
A storage battery assembly includes a plurality of electrochemical cells bundled in side-by-side fashion together in a row and electrically connected in series with each other by means of generally elongated electroconductive connecting pieces each connecting a pole terminal of a pair of pole terminals of an electrochemical cell with another pole terminal of a pair of pole terminals of a next adjoining electrochemical cell. Each electrochemical cell includes a generally rectangular box-like electrolyte vessel having an opening, an electrode structure accommodated within the electrolyte vessel and including positive electrode plates and negative electrode plates, a quantity of electrolyte accommodated within the electrolyte vessel, a top lid enclosing the opening of the electrolyte vessel, and pole terminals protruding outwardly from the respective top lid. An insulating cover made of synthetic resin and having a plurality of vent perforations defined therein is provided on the storage battery assembly so as to cover respective tops of the electrochemical cells with the vent perforations positioned substantially above the connecting pieces.
