I've been using hearing aid zinc air cells in my Nikons and my meters. I made my own adapters out of nylon stock on a lathe. Also, I block off three of the four airholes. This gives a cell life of 9 months or more - I don't really know how long, the cell in my Nikkormat was put in last April 1.

Edit - The cells are #675.
