## Long 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.
