The Dec. 8 Deal of the Day is the Motorola 2760 mAh extended battery (with door) for the Droid Bionic. This extended battery fives you nearly 60 percent more juice over the stock 1750 mAh battery that comes with the Droid Bionic. It is a little bigger, so you'll need to use the extended battery door that comes with, but that's all the hassle there is. No more worrying about running out of juice while you're chewing on the Gs. And the battery's manufactured by Motorola, which as always a plus. Best of all, it's available today only for $39.95 -- that's 20 percent off. Get yours while supplies last.
