Pros Rechargeable--to a point
Cons They die (as in stop holding a charge) VERY QUICK
Don't last nearly as long as the 4 RadioShack [rechargeable] batteries I found in the road-including one that has a dent in it
Summary OK, So I needed some rechargeable batteries for my game controllers which I classify as being high-drain and I bought these Duracell rechargeables as they said they are quote "ideally suited for high-drain or frequently used devices". So I charged them and they worked fine. Then after a few weeks, and the batteries having been charged only around 4 times, They stopped holding a charge. I used them in an xbox 360 controller when they worked. But when I went to use them again, all they would be able to do was light up the button on the controller for a half-second before it flickered off. I tried charging them again and it did not help.
I feel like I just wasted my money on something that was supposed to be good for 100's of charges, just to end up with less than 10. Their website says quote "Get hundreds of uses out of each Rechargeable battery. These powerful NiMH batteries are ideally suited for high-drain or frequently used devices". I did not in any way get even a fraction of that many charges.
All in all, don't buy these. Buy the RadioShack ones instead.
