OverviewHistoryConstructionUsesChemical reactionsZinc-chloride "heavy duty" cellStorageDurability
A zinc–carbon battery (or carbon zinc battery in U.S. English) is a dry cell primary battery that provides direct electric current from the electrochemical reaction between zinc (Zn) and manganese dioxide (MnO2) in the presence of an ammonium chloride (NH4Cl) electrolyte. It produces a voltage of about 1.5 volts between the zinc anode, which is typically constructed as a cylindrical contain…

in the insulating paper surrounding the battery, or mercury may be mixed in the anode itself. All of the different button-cell batteries can contain up to 0.005 grams (5 milligrams) of mercury ... zinc carbon, lithium, silver oxide, and zinc air. Manufacturers of these batteries were required to set up a collection system by January 1, 2016.2
An alkaline battery (IEC code: L) is a type of primary battery where the electrolyte (most commonly potassium hydroxide) has a pH value above 7. Typically these batteries derive energy from the reaction between zinc metal and manganese dioxide.. Compared with zinc–carbon batteries of the Leclanché cell or zinc chloride types, alkaline batteries have …
