alkaline battery

Alkaline batteries are a type of power cell dependent upon the reaction between zinc and manganese dioxide (Zn/MnO2).Compared with original zinc-carbon batteries, while both produce approximately 1.523 volts per cell, alkaline batteries have a higher energy density and longer shelf-life.Compared with silver-oxide batteries, which alkalines commonly compete against in button cells, they have lower energy density and shorter lifetimes.
