Thanks, Dan! Good lookin' out!
It sounds like he purchased this battery: https://www.ifixit.com/Store/Mac/MacBook-Pro-13-Inch-Retina-Late-2012-Early-2013-Battery/IF123-010-4
If that's true, then the manufacture date is probably correct, as these are OEM batteries made around that timeframe. However, I'm not able to find any of this customer's info. This appears to be an EU customer, and iFixit US does not share the same customer database. Therefore, I have no way of pulling up the exact battery he ordered by PartID and comparing that with the others of the same. We'll have to direct him to our EU Support team for assistance, to see if the battery is performing well enough or to see what his options are.
Thanks again!
