Encyclopedic overview
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, alkaline batteries have a higher energy density and longer shelf life yet provide the same voltage.
