Ämne: [OM] Battery drain & used body testing
>Newcomer to this mailing list, so hello everybody.
Hi Mica.
I might be wrong here but maybe you are the first Finnish subscriber
to this list. We have Swedes, Danes and Norwegians here, but I have
wondered where all the Finns are. Maybe they are all occupied with
using their mobile telephones? :-)
(explanation: Finland is the mobile telephone densiest country
compared with the size of the population)

NEVER use anything else than silver-oxide batteries of the SR 44 type
(or equivalent). For more info on suitable types of batteries for
different OM bodies look at the Olympus OM SLR FAQ at R. Lee Hawkins

Nowadays there is a cheaper alternative with silver-oxide batteries of
the 357 type. In Sweden they cost from 9 to 14 SKR a piece, and I buy
mine in stores that sell electronic stuff like calculators,
amperemeters and laser pens and such. They are just as good as "real"
SR 44 batteries.

I wouldn´t sell a body without testing it with the right type of
batteries.

'B' setting prevents the battery drain that occurs when the shutter
release button is accidently depressed like if something is put on top
of the body in a case. Otherwise the battery drain is always there.
For your other questions I'm sure there are many other more
knowledgeable people here that can help you. Good luck with your OM
equipment!
