## Long description

The Duracell MN21 Alkaline single-use battery is a cylindrical 12 V cell designed for consumer and industrial applications where a reliable primary battery is required. This small, blister-packaged battery uses Duracell's alkaline manganese dioxide chemistry and is suitable for devices that need stable voltage and dependable performance in a range of temperatures.
Advantages
Duracell alkaline batteries use a zinc anode, manganese dioxide cathode and potassium hydroxide electrolyte, providing higher energy density and lower internal resistance than traditional zinc–carbon cells. These characteristics enable better performance at moderate to high discharge rates, a relatively flat discharge curve and a long shelf life — typically retaining up to 85% of capacity after four years of storage at 21°C.
Suitable for
 Remote controls and key fobs
 Small electronic devices and sensors
