new battery for Samsung Galaxy S4 phone

I recently ordered this battery from Amazon: Galaxy S4 Battery : Stalion® Strength Replacement 2600mAh Li-Ion Battery for Samsung Galaxy S4 & S4 Active [24-Month Warranty] with NFC Chip + Google <https://www.amazon.com/gp/product/B00JJXTQOK/ref=od_aui_detailpages00?ie=UTF8&psc=1> I never opened the box since by the time it arrived my cell phone had died of unrelated causes, and I upgraded to a different phone. I paid $12.99 for the battery. I would like to sell it for $11 OBO if anyone can use it. Irina
