Product information

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
  • Security devices and alarm remotes
  • Low- to medium-drain consumer electronics

Key specifications

  • Battery type: Single-use alkaline
  • Model: Duracell MN21 (Duracell-MN21, EAN 5000394203969)
  • Voltage: 12 V
  • Weight: 7.4 g
  • Pack quantity: 2 pc(s)
  • Typical energy density: ~163 Wh/kg (75 Wh/lb)
  • Operating temperature range: approximately -20°C to 54°C
  • Shelf life: up to 4 years with ~85% capacity remaining at 21°C

How to use

Insert the Duracell MN21 battery into the device following the polarity markings. Ensure the battery fits the compartment correctly and that contacts are clean and free of corrosion. Replace both batteries in multi-cell holders at the same time and dispose of used alkaline batteries in accordance with local regulations.

Usage recommendations

Store batteries in a cool, dry place at room temperature to maximize shelf life. Do not recharge, short-circuit, puncture or incinerate. For best device performance, use fresh batteries and replace them promptly when device operation becomes weak or intermittent.
