Hi, Frantisek, The mercury cell is a px400, but they can be pretty hard to find, as they've been illegal in many places for quite some time. I think Varta might have been one of the last to make them, but they've now stopped.
I've heard of some Spottie users who've used the alkaline replacements successfully. AFAIK, the only downside of alkaline is that they don't last as long. Maybe 6 to 12 months (?), as opposed to 10 years or more for mercury cells. They are wonderful cameras, aren't they? :-) regards, frank Frantisek Vlcek wrote: > Hi, > what's the proper battery for an M42 Asahi Pentax Sp1000?
