Energizer - EL-223 - CRP2 Advanced Photo Lithium Battery
Digital cameras can drain your regular batteries dry with only a few shots. Keep spare battery or two, or use higher capacity batteries like lithium based ones. Some NiCD, NiMH or alkaline batteries do not have the capacity or high energy discharge rates to keep up with today's high powered cameras. Check your camera manufacturer's recommendations before changing the chemistry or battery capacity to see if it is supported by your device.
