A tubular battery has a hollow-cylindrical outer casing (1). A cell supporting body (7), into which individual primary cells (4, 5, 6) can be inserted such that they can be removed, can be pushed into this outer casing (1). The cell supporting body is designed such that the primary cells inserted therein form three cell groups (4a to 4e, 5a to 5e, 6a to 6e) each having five primary cells which are connected in series with one another, the cell groups then be connected in parallel with one another. A stop disc (25) is provided on one side of the cell supporting body. When the cell supporting body is in the pushed-in state, an annular stop surface (27) of this stop device (25) rests on one end of the outer casing. A contact disc (9) is screwed on over a threaded pin (8) which is arranged on that side of the cell supporting body which faces away from the stop disc (25). The cell supporting body is held in the outer casing once the contact disc has been tightened. Both the threaded pin and the contact disc are produced from an electrically conductive material. The threaded pin projects on the outside of the contact disc in order to form a pole cap (2), the positive terminal of the tubular battery. This invention makes it possible to form a tubular battery having a predetermined voltage and predetermined external dimensions by the use of commercially available small primary cells. The individual primary cells can be removed once they are dead, disposed of and replaced by new cells. Otherwise, all the other parts of the tubular battery according to the invention can be reused. <IMAGE> |
