Alkaline battery
From Wikipedia, the free encyclopedia

Alkaline batteries are a type of power cell dependent upon the reaction between zinc and manganese (IV) oxide (Zn/MnO2).

Compared with original zinc-carbon batteries, while both produce approximately 1.5 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.

The alkaline battery gets its name because it has an alkaline electrolyte of potassium hydroxide, as opposed to the acidic electrolyte of the zinc-carbon batteries which are offered in the same nominal voltages and physical size.
