Still, to tell the difference between a real mercury cell for your OM1 and a

That's what my understanding is too. I'm concerned that I'm not using the
correct voltage on the various OMs and that when they are drained this may
cause of the lock-ups I'm experiencing. After a long sit in the bag
(yes...a day without photography IS sad indeed, and not only that, your
batteries suck their little lives out in the dark abyss of their
non-working dwelling) you don't know what is really ready, if anything.
What might be really useful is a home-made 'battery tester' using a
multimeter and an empirically derived resistive load to tell us if that 357
OK...I think it's the multimeter is what I had in mind, but what about the
'empirically' derived resistive load'?
cell is close to failing in our OM-2S/OM4(T) bodies. We already know that
the body's built-in tester won't warn of of impending demise.
Yup, the body says all is fine, and it's not. Works for a couple of shots,
then locks. After a sit, it finally fires.
I was thinking too about putting a table together for the various OMs we
all have with the recommended battery (original) and replacement(s) options
+ voltage so that someone like me could figure out what to do on a shopping
spree, guided by a chart of all my needs in one place. When you operate 3
OM models, + 3 flashes, and don't use them all often enough (OK hit me now)
it would nice to have. Has anyone on this list put something similar to
this together already?
