Are they alkaline Rayovacs? If so, which model are they? High energy or the Fusion line?
I was happier than a pig in you know what, when I discovered a small "mom & pop" store here locally that sells Sony alkaline C and D batteries made in Japan. The AA's are made in Indonesia, and carry all the trademarks of normal alkalines made in FDK factories (Gritty surface on both terminals, green washer around negative terminal)
