Hi again, I forgot to mention that IKEA sell great batteries at an affordable price (I'm Swedish and I shouldn't have forgotten IKEA...). They’re branded "IKEA LADDA" in Sweden and have very similar specs as the Eneloop batteries, maybe they’re actually the same batteries in different packages. I have quite a few of them too and I’m happy with their performance.
PS. I'm not sure if they're called "LADDA" worldwide. ("LADDA" is a Swedish verb that translates into "CHARGE".)
