A multi-tubular battery plate comprises a plurality of tubes containing active material and a conductive spine extending along its length. Each tube is closed at one end by a bung 10, and the bungs are connected together to form a bottom bar. Each bung affords a space within it accommodating the end of a spine and having a seal, such as a flange 22 forming a frustum at its upper end, which surrounds the spine and through which the spine may slide. Thus any increase in length of the spines can be accommodated by the bottom bar and does not stress the components or seals of the battery in which the plate is used. <IMAGE> |
