A holder for dry-cells, for example for use in an electrical re-charging unit for dry-cells, has locating means for a dry-cell or a line of dry-cells disposed end-to-end in electrical series, and electrical contacts for the base and central electrode of the dry-cell or, where there is a line of dry-cells, of the two endmost dry-cells respectively, the first contact being radially offset so as not to make contact with the central electrode of a dry-cell which is placed the wrong way round in the locating means. In a preferred arrangement the locating means is in the form of a channel with steps in its sidewalls so as to provide pairs of shoulders which will support different diameters of dry-cell at different levels; in this arrangement the offset first contacts 18a, 18b, 18c for all the sizes of cell are rigidly interconnected and the second contacts for all the sizes of cell are rigidly interconnected. <IMAGE> |
