Originally posted by rskura Interesting, I'll have to try it out. I'm not sure what "vintage" my old K-7 battery is. I'll try it out tonight, to see if it makes any difference with a different battery in the grip. I already know that either battery in the body works fine.
I've never had the problem when using only one battery, regardless of where it was.
From Neil959's post, it appears that as long as at least one of the pair is a Ricoh-Pentax battery you can get the problem. So they both would have to be something else.
I'm thinking about buying a couple 3rd-party batteries just to see if I can replicate Neil959's result. They're cheaper and usually crappier but may be worthwhile if they solve this, admittedly minor, annoyance.
