We have written about the USBCell USB rechargeable AA batteries in the past, we are fans. The batteries are now officially available in the USA so look for them at Amazon or USBCell.com. USBCell also plans on releasing AAA and 9V versions in the near future. Still not convinced, watch a totally random USBCell video after the break.
I’ve had these for like 2 years. These have been in the US for quite some time. Microcenter has had them for at least a year.
Anyway. They aren’t all they are cracked up to be. LONG recharge times and short battery life. I tried to use these on my bluetooth mouse. Spent more time charging them than using them.
