I got 2 free samples AA batteries from http://www.USBcell.com in 2007 during their demo (at DEMO), and I've been using them ever since to this date with my wireless Microsoft mouse. I found out that my mouse will work with just 1 AA, so while one is being used, I stick the other in the USB drive (to charge), and I just swap when the one in the mouse runs out. And it's been 3 years!!!

No shaking required.

Whenever I replace the AA from my mouse with the one I just unplugged from the USB drive, I time how fast I can "reload" <-- used to play Time Crisis 1 and 2 obsessively back in high school :D
