1. In a battery construction comprising an enclosure, a plurality of self-contained electrochemical cells electrically interconnected and housed in cell-to-cell contact within the enclosure and a pair of output terminals mounted on the enclosure, an improved enclosure comprising:
- a top closure having an uppermost surface;
a bottom closure spaced from the top closure; and
a side closure surrounding the electrochemical cells and mounted to the top and bottom closures;
said bottom closure having a generally planar bottommost surface from which project a plurality of discrete upstanding locator stops positioned inwardly of the side closure and upstanding less than the height of the cells, the side walls of said cells being in direct physical contact with one another said stops, together with the side closure, limiting lateral movement of the cells relative to the enclosure.

Abstract
A one-piece top closure for a battery enclosure such as a lantern battery is described including a substantially planar top surface in which is integrally mounted a recharge jack of improved design, and in another embodiment there is disclosed discrete spacer elements integral with the top closure and which project to bridge the space from the surface of the top closure to the electrochemical cells contained within the enclosure.

4. In a battery construction comprising an enclosure, a plurality of self-contained generally cylindrical electrochemical cells in side by side physical contact with one another electrically interconnected and housed within the enclosure and a pair of output terminals mounted on the enclosure, in combination an improved enclosure comprising:
-
a top closure having an uppermost surface; a bottom closure spaced from the top closure and; a side closure surrounding the electrochemical cells and mounted to the top and bottom closure; said top closure having discrete integral projecting elements bridging the space extending from the uppermost surface from the top closure of the cells; said bottom closure having a generally planar bottommost surface from which project a plurality of upstanding stops formed of arc segments making contact circumferentially with the electrochemical cells and which, together with side closure and projecting elements in particular limit movement of the cells relative to the enclosure.
