Zincâcarbon batteries of various sizes. A zincâcarbon battery is a dry cell battery that delivers a potential of 1.5 volts. Although carbon is an important element of the battery's construction, it takes no part in the electrochemical reaction. The cell could more properly be called a zincâmanganese cell.incâcarbon batteries of various sizes. A zincâcarbon battery is a dry cell battery that delivers a potential of 1.5 volts.
