Battery Replacement from "OEM replacement"

I recently replaced an old battery that had well over 1200 power cycles on it. I came upon finding an "OEM" replacement on Amazon and purchased it. After installation the battery showed 50% charged which I hear Apple does do their batteries, so I figured it was authentic.

After doing a complete charge and drain for battery calibration, the attached image shows something odd... It seems like it already had lost 7.8% of it's Design Capacity but charged above 100%...

Another thing I had noticed was that under the Battery Info... it shows that there is a battery failure.

What should I do? Any help would be much appreciated! Thank you.
