    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.

    For your Rollei, you may be able to find an O-ring at your local hardware that will hold it centered in the compartment. I don't remember the # of the cells I use, but they are the size of an S-76 and come out to just under 50 cents each.

    Edit - The cells are #675.

    I recommend the CHRIS adaptor highly. I use them in my Leica CL camera, Weston Ranger and Metrastar meters as well as a couple of other cameras and the exposure meters were near spot on when compared to using the PX625. I do agree that if the unit can be recalibrated to use an alkaline battery it would be a godd way to go, maybe the better though more expensive than the CHRIS. I had my CL gone through just before the mercury battery issue arose but, if it needed any other work again, I'd have it recalibrated.

    The adapters that use hearing aid cells (#675) work well, and those cells are really, really cheap. It's easy to keep a couple of unused batteries in each bag (and I have way too many bags).

    The CRIS adapters are great as well - I used one for a long time in an OM1 that I sold a while ago.

    Hearing aid cells are wonderful. They work in most -70's mercury cell cameras. What comes to Rollei 35 in particular I think its meter is no good. It fails just when you need it (in the shadows or inside). It seems to need a certain amount of light to wake up. I'm happier without it.

    Does anyone have any experience with these?
    You can "re-use" the Wein cell the same way. That is, the ring slides off and can be re-used on a fresh battery.
