That's an excellent hint! |
I've had a zinc-air battery in the Revueflex for 7 months now...in that time, I've run about 6 rolls of film through, covering the air holes after my sessions.
Interestingly, I have a hearing aid too, so I buy hearing aid batteries in bulk.
As long as the air holes are covered, there is a shelf life of at LEAST five years, based on my personal experience! 
I'm STILL waiting to use up the battery in the Revueflex....  ...same situation with the Contaflex 126...

Martin, Matt etc
If you have an alkaline cell (which won't last too long before the voltage begins to drop), you can use the shell of it to make your own adapter to use a cheap 1.55v silver oxide cell. It's a simple job:

I also found a site in Japan that sells 625 adapters similar to the Criscam one, quite cheap too (about £15.50):
