There is one catch with Eneloop batteries, they have a lot less capacity than other NiMH batteries.
They start with 2000mAh and after a year discharge to 85% ie 1700 mAh
Other NiMH (Duracell for example) start with 2650 mAh and discharge at about .75% per day so will take about 40-50 days to get down to the same level of charge as the Eneloop.
So, Eneloop are great as a spare set to keep for emergency, but standard ones are better if you charge them more frequently than every 6-7 weeks.
Eneloop are more expensive, so I use Duracell for regular use with a set of Eneloop as an emergency backup.
