Just picked up the 2 Battery and Charger combo on Ebay. Came from Hong Kong and I paid, 9.99 plus Free Ship. It took 2 weeks to get to NY. The Batteries are 3.7 v DC and 1500 mAh. The HTC battery is rated 1400 They fit in the phone and take charge well. I plugged in my USB cable and it is charging from the PC normally. . ( not the case with my fascinate when i tried this ) At the end of the day, with my HTC battery I would normally have between 25 and 33 % before charging it for the night. I have been at a consistent 40% all week, with the new battery. I thought for certain I would be changing out the two new ones between another. But not the case. So everything works, In case anyone was interested. I can give you the users name I purchased through. PM me if interested.
