Here was one page that has some about the matter. From what I've
learned over the years, carbon zinc cells are nearly useless for high
current draw applications. It's nicad and NiMH that do well with high
current. I don't think carbon zinc cells would do as well.
About 20 or so years go, I did an informal test of carbons versus
alkalines. I tried high drain (Pocket flashlight, might have been AA
size mini mag) versus low drain tape recorder that I used about an
hour a day (four C cells). In both tests, the alkalines lasted four
times as long as carbons.
I encourage you to feed your Lumix one carbon, and one alkaline.
Replace the carbon as the camera goes into low battery, and let us
know how many carbons equal one alkaline. Actually, I may buy a pack
of four AA carbon zinc cells at the Dollar Tree, one day. And take a
bunch of pictures around the house just for fun.
