1. A storage battery system comprising at least one of battery modules each comprising a plurality of batteries,each of said plurality of batteries having a battery casing and including an electrode group which is composed of positive electrodes using metal oxide as an active material, negative electrodes made of, as a main component, hydrogen storage alloy which electrochemically absorbs and desorbs hydrogen, and separators, and which is disposed in said battery casing;

  • said plurality of batteries being arranged in rows with spaces being defined between adjacent those of said plurality of batteries;

    said electrode group having a dimensional relationship such as H>

    L>

    W, where H is the height of the electrode group, L is the width of the electrode group, and W is the thickness of the electrode group;

    a value K which is obtained by multiplying the width L with the thickness W, that is, K=W×

    L falling in a range such as 10≦

    K≦

    100; and

    ,a ratio D/W between a width D of spaces between the adjacent those of said plurality of batteries and the thickness W of the electrode group falling in a range such as 0.02≦

    D/W≦

    0.3.
