These are the best I've tried
, June 13, 2009
These Powerex AA rechargeables are the best I've tried.
I've tried several different brands of NiMH AA batteries (Delkin @ 2900 mAH, Power2000 @ 2500 mAH, La Crosse @ 2600 mAH, Duracell @ 2650 mAH, and DigiCam @ 1800 mAH). I use the La Crosse BC-900U charger on all of them so that I can see to what capacity they can be charged to, and even the La Crosse batteries that came with it can't be charged up to their own stated capacity. Duracell and Delkin both had a dud in each 4-pack of AA batteries. For all five manufacturers, the fully charged capacities of their AA batteries never exceeded about 80% of their stated capacities. None ever came close to a "full charge'. There was always at least one in each pack (excluding the dud in each pack) that would only charge up to about 50-60% of capacity, which would lead to a premature "Low Battery' shutdown of my camera.
The Powerex on the other hand, all charged to 95%+ of their rated 2700 mAH capacities and really last!.
