IMO, alotho since the Mugen batteries are of higher quality than the stock HTC batteries, your increase in life will not be worth the cost for the battery plus shipping. I suggest going to your local sprint store and seeing if they have any extra batteries they would be willing to supply you with, then get a dock/spare battery charger and rotate between them. My store gave me 2 extra batteries and i also purchased the 3000 mAh battery by Mugen, and i use the docks spare battery charger and rotate between the 4, mostly using the big one for when I'm gonna be away from a charger all day...
