I for about three months using the Sanyo Eneloop batteries now in my "Canon PowerShot A620" digital camera and can recommend the batteries fully. While the batteries previously used - even when not using the camera - were discharged after 2 days in the Eneloops no self-discharge is detected. I now have about 50 photos, made partially with flash, as well as several short movies and the batteries had not been reloaded.
If only for the environment you should upgrade to this new alternative.
