Product information

Description

The Duracell MN21 is a single-use alkaline battery with a nominal voltage of 12 V and a compact cylindrical form factor. Weighing 7.4 g and supplied in a blister pack with two cells, this battery is designed for consumer and light industrial devices requiring a small, reliable primary power source.

Advantages

The Duracell alkaline chemistry (zinc/potassium hydroxide/manganese dioxide) provides higher energy density and lower internal resistance than traditional zinc–carbon cells, enabling stable operation at moderate to high discharge rates and across a wide temperature range. The battery retains a high percentage of its capacity during storage, offering long shelf life which makes it economical for medium- to high-drain applications.

Suitable for

  • Key fobs and remote controls
  • Small electronic devices and sensors
  • Portable medical and measurement instruments with 12 V cell requirements
  • Backup power for alarm systems and small security devices

Key specifications

  • Model: Duracell MN21 (MPN: BAT23.D2, EAN: 5000394071117)
  • Chemistry: Alkaline (zinc/manganese dioxide, KOH electrolyte)
  • Voltage: 12 V nominal
  • Configuration: Single-use primary cell, cylindrical
  • Quantity: 2 pieces per blister pack
  • Weight: 7.4 g (0.0074 kg) per cell
  • Typical energy density (system reference): ~163 Wh/kg
  • 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 cells into the device respecting polarity markings. Use only as a single-use primary alkaline battery; do not attempt to recharge. Replace both cells at the same time when the device indicates low power or when performance degrades. Dispose of used cells according to local regulations for battery recycling or hazardous waste.

Usage recommendations

Store unused Duracell MN21 batteries in a cool, dry place at room temperature to maximise shelf life. Avoid exposure to high temperatures and direct sunlight. For devices with continuous high drain, check compatibility and expected service life before extended use.
