A leak-resistant dry cell comprises a negative electrode formed by a zinc tube which is designed to be consumed when the cell voltage has fallen to e.g. 0.75 volt, a sealed bag of flexible plastics material enclosing said zinc tube and surrounded by a cylindrical jacket, a carbon positive electrode projecting through said bag and sealed thereto, and a tongue extending from the edge of the sidewall of the zinc tube through said bag in sealing relationship therewith, the tongue contacting a negative terminal of the cell. |
