Just thought I would share this. I just bought a spare battery for my Droid 2 on Amazon for 5 dollars. It's an OEM battery sold directly through Amazon--not an authorized seller.

I got this as an emergency backup when I travel to D.C. later in the month. The last thing I want is to be in a strange city without Google Maps in my hand.
