Rechargeable Battery Panasonic
The best brand of Aaa Rechargeable Battery?

Hi I'm buying a few AAA rechargeable batteries. I'm pretty sure they're all the same, but I am searching Sanyo, Sony, Panasonic and Energizer. Any difference between them (from what I've found that are almost the same price)?

I'm not sure about of others, but I had 4 that I use alternately energizing (two at a time) for almost 4 years and still going strong.
