Hi Peter .... I got slightly over 700 exposures with plain vanilla Lithiums (energizers) and the CR3V's that came with the DS. That included a fair amount of chimping while learning the camera and, for all intents and purposes, no use of the flash, and using auto focus lenses about 1/3 of the time. Just about every exposure was made with the RAW setting (if that means anything).
