I've used AA and AAA Eneloops for perhaps 4 years now, and charged them with an inexpensive (<12$) charger many times with no problem.

Last year (based on a tip I got in this very forum) I splurged and bought a La Crosse Tech BC-9009 from Thomas Distributing, who no longer sells them. It cost $56+$8 s/h and included 4 excellent 2600 mah AA cells and 4 AAA cells. It is nearly identical to the Maha MH-C9000, except the Maha has a different display and no cells. I suspect a common chinese manufacturer. I actually started using these La Crosse cells since they're 15-20% more capacity than the Eneloops. They're in my Dinotte 140 taillight right now.

The Maha C801D looks fine and is functionally the same as the Maha C9000, except for 8 circuits instead of 4, for $20 more. IMO the C9000 is a better deal. I have so many spare cells I can get by fine with a 4 circuit charger - maybe you can't.

All three of these chargers have a number of programmable features. You can completely discharge and then recharge and measure the actual cell charge capacity in mah, for example. You can fast charge or slow charge. The default charge current on the LC BC-9009 is 200 ma, which takes forever on a AA recharge. So, I charge AAAs first, then put the AAs in before bed. I can turn it up to 1500 IIRC, at which point I'm back to my now-backup-only $12 charger functionally.
