Hi Bill - Earlier this year I purchased a LaCrosse BC-1000 smart charger and several sets of AA and AAA Sanyo Eneloop XX batteries from amazon. I must say thus far, I am impressed with both battery sizes and especially the charger. I have several older AAA and AA batteries (Energizer and Duracell NiMh) and used this new charger to "refresh" them. In the 4 years of using those old batteries, I have never seen the fully charged state indicate 1.5V and rated full capacity; these and most other older NiMh I believe are all rated at only 1.2V. If the initial few months of use is any indication of charger performance, this will be one of my best investments! I read several positive reviews on Sanyo XX Eneloops, and that is what finally drove my decision to purchase. They are not the cheapest out there, however with a rating of 2500mA and getting the voltage to 1.5V, I think these will perform better than your average rechargeable. They even feel much heavier than the other brands I have, which may be an indication of better quality build, not sure. They apparently hold a charge longer than most others as well, so leaving them in your camera bag until you may need them is not an issue. I use the AA's in Speedlight flash and also as backup for my grip. Unbelievable how many shots can be had before recharging is necessary!

Just my thoughts. Good luck.

Take care; these NiMh cells have a maximum voltage of 1.2v not 1.5v, as do all cells of this ilk. Many cameras and other devices require to know if you are using NiMh or Alkaline cells, the circuitry then allows for 1.2v or 1.5v accordingly. 1.2v NiMh appear to be the preferred cells, I believe they run cooler than 1.5v alkaline, and they definitely last a great deal longer in the camera before needing a recharge. The latest incarnation of the Eneloop brand are 2000 mA capacity but with an expected life of 1500 recharges. Recharging is best done slowly - a fast charge time at the higher rate of mA will kill the cell quite quickly.
