Nikon DB-2

Description

The Nikon DB-2 is an anti-cold battery holder for the Nikon F3, FE/FM series, the FA, and others. Just screw in the cord where the batteries would normally go and pop a pair of AA batteries into the holder. In addition to extended battery life, you can toss the holder into a warm pocket and minimize the effect of extreme cold weather on the function of your battery-powered camera.
