1. A multi-cell rechargeable battery, comprising:
- a case including an upper layer having an upper cover, a lower layer having a lower cover, and a single shared intermediate wall between the upper layer and the lower layer, the case further containing one or more directly adjacent partitions dividing the interior of the case into a plurality of cell compartments, the directly adjacent partitions being perpendicular to one another, each cell compartment having a pair of side walls and a pair of face walls, each cell compartment sharing at least one side wall and at least one face wall with an adjacent compartment, at least two cell compartments being provided on each of the upper and lower layers;
a plurality of electrical terminals comprising a plurality of upper terminals associated with the upper layer and a plurality of lower terminals associated with the lower layer, wherein the partitions are composed of a metallic material or a metalized material; and
a rechargeable cell element disposed within each of the compartments of the case.
