Good info, thx.I don't think that is true. As I don't think the middle port of the part number, he "-00-" or "-01-" has anything to do with if it is a reman or not. (That position seems to normally be related to versions of the part for other regions.) The label clearly calls out that it is a reman pack.
However, I think the "R1" on the end of her serial number indicates that it has been remanufactured once.
Also, the way I read OP's replacement pack label is that it's originally a May 2015 pack that has been remanufactured once - T15E and R1.
That said, one cannot tell from Tesla's label when the reman was done. Could be anytime from 2015 to present.
Given this uncertainty as to when the Tesla reman was done and @wk057 not even putting on a label (Reman pack labels in the wild), I'm wondering about the
older Tesla out of warranty resell market (either dealer or private party).
A savvy buyer might want to know about any replacement pack. A seller will advertise a reman pack to assure that the pack is newer then the original. Currently one can tell with Tesla, not the year of reman but that's it's a reman. However with someone like 057, one would have to contact them for info if there is no type of replacement label.
Now a private party will probably have "paperwork" while a dealer may or may not.
