Thanks for this, I noticed it wasn't posted anywhere either.
Yes, it's listed in the weekly (the one with the "Sylvania 19in LCD HDTV" on the front) for 9.99. I'll be picking one up tommorow for a friend.
I've had nothing but problems with my 360 rechargeable batteries. Mine lasted for about 1 1/2 years and then suddenly wouldn't hold a charge at all. I've gotten several since then, including a blue one for my other controller. I only ever play by myself, so I used the blue controller for a few months, went back to the white one (which I had just replaced the battery on a few months ago) and it's battery is dead again, won't hold any charge. Used the white one for several months, went back to the blue one, and now IT'S dead. Therefore it seems to me that you can't charge these batteries up and then leave them for any period of time, they will just completely die.
Also, when I plug my controller into the 360 and turn the console off, it does go into "standby" mode, the fan stays on and it charges the controller for a little while (about 20 mins), then turns off. If you then plug the controller into a pc, it thinks it's fully charged and will not charge any more.
The 360 rechargeable batteries are CRAP. But it's the best solution though, changing out regular batteries sucks, so you just gotta keep buying them over and over again.
EDIT: I have not used the Quick Charge dock before. It sounds like that will fix the problem
