The commonly available battery will run "hot" and tend toward underexposure.

I've been able to recalibrate the GIII to handle both the new batteries and 1600 film, but it's not something I would recommend unless you really want it.
Apparently I was misinformed in this thread here http://www.apug.org/forums/forum65/1...ion-twist.html. But I have taken many pictures with mine over the years with a plain alkaline battery and no problem.
