2. Description, technical data
The model for a dry cell battery was invented around
1860 by French chemist Georges Leclanché. The cell named
after him, which continues to be the most common bat-
tery even today, uses manganese dioxide and is not re-
chargeable. The Leclanche cell consists of a cylindrical
zinc electrode, a carbon electrode, a ceramic cell and a
glass vessel. The cell as supplied has no filling. When
filled, the Leclanche cell provides a voltage of
approx. 1.5 V.
Connections:
via 4-mm sockets
Dimensions: 175 mm high, 65 mm Æ
