OEM 2100mAH extended battery with back, only a few months old.
Had to send my device to Sprint to get out of contract but I hung on to this. If anyone wants it PM me with your deets, first come first serve. I hate to send it to the recycle bin when it still has most of its life left but I have no use for it. Only adds about 1mm of thickness to phone and for me it made all the difference in longevity, just that little boost I needed to get through the day.
