The Leclanché cell as depicted in Benjamin’s 1893 treatise on the voltaic cell.

The 24th issue of Museum Notes highlights the Leclanché voltaic cell in both its original wet-cell form and modern dry-cell form. This cell is the basis of most of our current everyday batteries from the D-cells used in traditional flashlights to the smaller AAA-cells used in many of our everyday electronic devices.
