The Canon NB4-100 AA NiMH Rechargeable Batteries works for every item that uses AA batteries such as Digital Cameras, Flashes, PDA's, CD players, MP3 players, handheld video games, portable GPS devices, and many more devices. It last a lot longer than AA batteries made of alkaline or niCd cells, which were ineffective for high-drainage and power-hungry devices.
