rechargeable batteries

I don't know if I have a defective batch, but the Duracell rechargeable AA batteries I picked up a few weeks ago seem to self-discharge. Prior to that, I had Energizer ones. I got the Duracell because it was 2650 mAh vs. the Energizer 2450 mAh.

I charged up the Duracells and gleefully put them in my camera. Weeks later, I took my camera out and noticed that the charge was low (maybe around half) even though I hadn't used the camera. I recharged the Duracells and repeated. Sure enough, the batteries were again below half after a few weeks of sitting up.

So, I vote for the Energizers. They've never given me this problem. I can leave my camera sitting up for months and the Energizer batteries still kept their charge.
