I love Sanyo eneloops. Both AA and AAA's. I know some will disagree with me, but their capacity is more than what they state on the batteries. I have tested them in my charger and they are very consistent. They are LSD (Low Self Discharge) batteries meaning they will only lose about 85% of their capacity over a year. So while they are not the highest capacity battery around, they will last longer because they will require less charging.
