Duracell No. MN21 Alkaline Battery
The Duracell No. MN21 12 volt alkaline battery was
manufactured for Duracell Inc. of Bethel, CT. probably around 2000.
The No. MN21 alkaline battery weighed 0.1 oz. (4 g) and measured 1⅛"
by ⅜" in diameter
(2.8 x 1.0 cm).
Note: this battery looks similar to the Type "N" 1.4/1.5 volt
batteries used in some older body-style hearing aids. Although it is 1
mm smaller in diameter and 1 mm shorter, it will fit in Type "N" battery
compartments. However, this battery is 12 volts (not 1.5 volts) and will
likely fry any hearing aid designed for 1.5 volts. |
