    Battery for OM-1

    Hi

    In a thread today I mentioned that I had an OM-1 lying @ home. Now I have taken it out and I am rather keen on shooting with it again.
    But the battery is missing, so I cannot see which one I need to buy.

    Can you me, APUGGERS?

    Hello Morten,
    Loads of info on the OM system:

    It uses an older mercury PX625 (voltage=1.35). Newer alkaline replacements will work but will bias the meter by about 1/2 stop I think (if its pumping out the 1.5V). Older battery might be hard to find though.

    I found this:

    One more IMPORTANT thing: I have completely solved the 625 mercury battery issue! Go to Home Depot, and buy a #9 rubber O-ring - It costs 29 cents, and then slip it in the empty battery compartment of your OM-1. You can then use the Zinc-Air 76-size batteries directly. These are the basis of the Wein cell, but they need not be bought at a high premium from limited channels like the Wein cell. They are hearing aid batteries, available at ANY Costco, Wall-mart, Radio Shack, etc. The voltage matches what the meter was built for, unlike any Alkaline or Silver Oxide replacements. So there is NO NEED to re-calibrate the meter. These batteries will wear out quickly (say, 1-2 months), just like the Wein Cell, but they cost 60-75 CENTS EACH in packs of 8 or more.

    Can someone tell me which battery to look for?

    Camtech, www.zuiko.com will upgrade your OM-1 to use newer batteries (recalibrate the meter). John, who has deep experience, will also do a clean and lube.

    I had him put in a beatty bright screen (with meter adjustment). My OM-1N is just as good now as when I got it in 1979 (has it been that long?). He also replaced my light seals.

    Very good service. I have no connection with him other than being a satisfied customer.

    How did that c get in there?
    www.zuiko.com

    Both John and Photosphere in Dallas will include the battery conversion as a part of their CLA unless you ask them not too.
