2840mAh 3.8V Internal Battery B0PGE100 Replacement for HTC One M9

Genuine batteries - Yes. New Batteries - No. They sell the item in poly bags and claim it is frustration free packaging, so that the savings can be passed onto the customer - Lies! They are sold in poly bags because the batteries are salvages from other phones. I bought a replacement battery for an HTC M9 and it did not hold as much charge as the battery I replaced - an hour of lost work!
