    OM-1 on the way! Battery question

    Hi all, I am really excited, I have got my 1st film 35mm coming, an OM-1

    I have read that the camera needs to be converted to run on non-mercury 1.5v batts.

    However, I have seen this:

    Will this work instead of converting my camera??

    Thanks

    These Wein cells do work but they have a limited life after opening as they work on a chemical reaction on exposure to air. Another option is a converter for 386 batteries such as the one offered by the Small Battery Company http://www.smallbattery.company.org....r9_adapter.htm. These are quite expensive but should last a good while and may be cheaper in the long run if you shoot a lot.

    Yes. But consider hearing-aid batteries. They are the same thing for about 1/5 the cost. Zinc-air batteries only last about 3 months. And keep an eye on them for corrosion. (Wein cells included)

    Contact Jon Goodman - JGood21967@aol.com - he sells adapters that permit use of the really inexpensive hearing aid batteries in cameras that were designed for the PX13 battery. I have no connection with Jon - just a satisfied customer.

    The hearing aid batteries (and the Wein cells) supply the right voltage and current. The adapter deals with the fact that the hearing aid batteries are physically much smaller than the PX13s.

    If I remember correctly the battery on the OM1 is only needed to operate the exposure meter. The camera will work perfectly without it. An external hand held meter is the better way to go, IMHO.

    Forget about the built-in meter. You can get a very nice incident meter which will do a great job for you...

    As you are in the UK, I can strongly recommend Mike Spencer at http://www.camerarepairs-r-us.co.uk/

    He's serviced and re-foamed 1 x OM1 and 2 x OM2 for me. When he services OM-1 he will convert to use SR44 silver cells which works perfectly. Old school and a real gent. It is worth reminding if you haven't had OM before that they had foam over the prisms under the top cover which degrades over time and corrodes the silvering. If the door/mirror foams are sticky, so will the prism foam be!

    He is indeed a very nice gentleman. You can call him and tell what exactly you want or the problems. Very reasonable pricing.

    All OM1 and 2 will have to be serviced anyway as the light seals almost certain will be deteriorated to some sticky goo. This stuff is also used to inside the housing and will ruin the prism by the time if it not already hasn't. So I strongly recommend a CLA. The cam is worth it. Every qualified repairsman will then convert the camera to 1.5V
