Zinc–carbon battery
OverviewZinc-chloride "heavy duty" cellHistoryConstructionUsesChemical reactionsStorageDurability
The zinc-chloride cell, frequently referred to as a heavy-duty, extra-heavy-duty, super-heavy-duty, or super-extra-heavy-duty battery, is an improvement on the original zinc–carbon cell, using purer chemicals and giving a longer service life and steadier voltage output as it is used and offering about twice the service life of general-purpose zinc–carbon cells, or up to four times in continuous-use or high-drain applications. This is still a fraction of the output of an alkaline cell, however.
