I've had great luck w/ the Sanyo Eneloop NiMH batteries.
Costco carries a large set w/ the charger, a large number of AA/AAAs and C/D "adaptors" that take the AA batteries and allow their use in C/D stuff.
The Eneloops are advertised as holding charge longer when idle as well as longer use times when "on". All came OOB with full charges. Between the Eneloops in the Costco set + the 8 NiMH AAs I already had been rotating for my dig camera---every battery operated thing in the house (save for the kids toys) utilizes rechargables.
For me, Eneloop life in a Wiimote is comparable to an actual alkaline AA such as Duracell. How long that is depends on level of use & whether or not you use the speaker & rumble functions of your Wiimote.
