Power is supplied by four AA batteries, alkaline, NiMH or lithium type may be used. We, of course, recommend the use of NiMH rechargeable batteries , they pack more power and they're reusable. Fuji lists the battery life at 300 frames using alkaline batteries. When using fully charged 2300mAh NiMH batteries you can raise that to 500 frames, based on CIPA standards.
