Quick Summary

An alkaline cell, also known as an alkaline battery, is a long-lived dry cell that uses an alkaline electrolyte, which reduces corrosion. These batteries are widely used in everyday devices like flashlights, toys, radios, and digital cameras.12

Alkaline batteries are a type of zinc-manganese dioxide system and provide an initial voltage of about 1.55 to 1.7 volts, which decreases as the battery is used. They became commercially available in the 1950s and are now a popular household choice due to their high power density and capacity. Modern alkaline batteries typically contain no added mercury, reducing their environmental impact.23
