I've been all over town today and nobody and I mean NOBODY has the proper cell battery in stock for my new Spottie F, which means I have to order a few from Amazon and wait a week to see if the light meter still works...ARRGH!!!!!! I don't know why but I thought this one took two LR44's which I have quite a few of. Nope, it doesn't. Takes a 625 cell apparently which I can't find anywhere even at the local "We carry them all!" battery store. Eh, that's okay. I need a few for my SPII too, guess I might as well order them all at once, sigh...
Okay, now wait a minute here....
I'm on Amazon looking and it says PX625 or PX13 and the PX13 is the same as the alkaline LR44 but it looks like the LR44 is too small???? Are the PX13 and PX625 the same size? Do I just need a washer or something maybe?
Eh, never mind I just figured out that they are supposed to be totally different. The 625's had a lip around the battery and they are bigger it looks like. So yeah, I guess I am ordering off Amazon instead. Darn, I was hoping these would be easier to get than the ones for my SP/SPII. The LR44's are all over here and are easy to grab. But not the 625's. I don't see either one locally, not Duracell nor Energizer.
Ah, this is a familiar problem to those of us who love the old Canons. The best solution is an adapter that'll let you use the very same LR44s you have around: they tend to run about 40 bucks and simply adapt the batteries to shape. In a pinch you can actually just stuff a 44 or 76 battery in the same space and pad it out a bit. (I think the spotties aren't voltage-sensitive as are most old Canons, but I'm not sure. That simplifies things, if so.)
The Px13 is the now-outlawed mercury cell version of the 625 alkalines: they are the same fit, but many old cameras require the consistent output of the mercury cell: the adapter I mentioned allows the use of silver oxides, (You want SR44s for that: still easily-available for hearing aids in about any supermarket) which are consistent enough that way.
I think, but I'm not sure, that the Pentaxes are less finicky about battery type than my beloved old Canons: For those, despite relaxed standards for mercury dumping since then, the proper mercury cell that I'd swear by Earth, sky, and water to be in proper care of ...is for most purposes unobtainable.
