I have the eneloops totally convinced for some months now in use and am. A current example: In my digicam I've with high performance rechargeable batteries (4x Mignon of 2700 or 2800 mAh) from different manufacturers reached a maximum 220-250 photos with a battery pack. With the eneloops I recently incredible 570 photos (of which approximately 80% with flash) achieved. Apparently keep these batteries by the end of the full voltage required by the apparatus for its operation. I have been completely disposed of my old batteries and converted to eneloops. I can recommend them without reservation.
