OM-1 batteries
I have been given an original OM-1 and would like to try using it. I know that the original battery is no longer available. I don't want to use the 1.5volt replacement if there is something closer to the 1.35v of the proper battery. I have put a 1.4v hearing aid battery in and it powers the meter. The readings look about right. Has anyone else tried this as a solution? If so, how long do these batteries last? They run for about 2 weeks in a hearing aid. Thanks.

I got a gismo from the Small Battery Company which is the same size as the old 1.35v. mercury batteries and fits in the battery compartment of my OM1. It takes a 1.5v battery, and drops the voltage to 1.35v. Works a treat, but not cheap.

I bought one of these years ago for my Leicaflex: http://www.butkus.org/chinon/batt-adapt-us.pdf It should fit your OM too.

I've always used a hearing aid battery with a collar in mine. It will last more than a couple of weeks, but I've never used the OM1 consistently enough to test the battery longevity. They're cheap enough and work.

Thanks for all the replies. There seems to be enough options to find s suitable replacement. I'm going to make a foam collar to support a hearing aid battery. I can then compare meter readings with my Gossen , and test how long the battery lasts. Alex

There is a camera repairer in Derbyshire who will perform an Olympus OM 1 body conversion to take SR44 batteries, installing new foam door seals, mirror buffer and service.
Contact camerarepairer@btopenworld.com. You end up with a 'new' camera that will last a further 20 years. I had mine done. |

Apparently if you block up a couple of the tiny air-holes in the zinc-oxide battery it will last much longer without affecting performance. I presume light-meters are far less power-hungry than hearing aids.
