Abstract: A lithium-sulfur-dioxide battery (e.g., the BA5847/U) is modified so that can be used both in its customary manner or as a substitute for a standard Leclanche battery (e.g., the BA210/U). Since the aforementioned batteries typically have their connectors at different, distinct locations, the first-mentioned battery is provided with a second set of connectors (i.e., female sockets) which are located at the very same position as the connectors of the battery it may be substituted for. Thus, this battery has two sets of (2-hole) connectors and these are, in turn, interconnected in parallel.

Abstract: An interconnector device permits a lithium-sulfur-dioxide battery (e.g., BA5847/U) to be substituted for a standard Leclanche battery (e.g., the BA200/U). The lithium-type battery can therefore be used in its customary manner or, with the interconnector, as a substitute for the Leclanche battery; battery proliferation is thereby reduced. The interconnector comprises a rectangular wafer of plastic material with a pair of prongs mounted on one flat surface of the wafer and at a location which corresponds to that of female sockets of the lithium-type battery. A pair of coil spring connectors are mounted on the opposite flat surface of the wafer and at locations which correspond to the locations of the coil spring connectors of the Leclanche battery. The prongs and coil spring connectors of the interconnector are electrically interconnected in parallel.
