Need more juice for your HTC ThunderBolt? Yeah, you do, especially if you're rocking LTE on this thing. It just sucks through a battery. You're going to need an extended battery. And the official HTC 2750 mAh extended battery for the HTC ThunderBolt is now on sale for $39.95.
That's nearly double the juice over the stock battery. And it comes with an extended battery door, direct from HTC, so it looks and feels like it belongs on the phone.
