A look at a vintage Leclanche cell. (Very early battery.)

Leclanche cells were one of the first really popular batteries. They were often used in series clusters to power maid/butler call systems and early telephones. They were the precursor to the fully enclosed zinc carbon "dry cell", followed shortly after by the zinc chloride cell.

Please note that the zinc "anode" is actually the negative terminal.
