FOUR DOLLARS, from HTC (not some x-brand).
It's worth charging, and tossing in your glove compartment. It's legit. Get it!
are you the seller?
Just kidding. Good deal. I bought one like this for my dinc on ebay. Everyone swore it was junk, and it would last 3 months tops. I just retired the dinc, and after 18 months of using that battery alongside the stock battery (used a seidio charger for the batteries...I never plugged the phone in, just shut down and swapped batteries when it was dead) that battery was still working fine. It was starting to not last as long as when I first got it, but so was the stock battery. I'd say they had lost about 20% of their capacity based on the usage I was getting. For $8 (with shipping) it's worth the risk.
Now if I can only find the adapter piece for the Seidio chargers for the Rezound battery so I don't have to buy a whole new charger.......
HTC Incredible (AMOLED) rooted S-off
HTC Rezound unlocked & rooted
Unlocked MDK Rooted Galaxy S4
If it ain't broke....fiddle with it to try to make it better.
