In all fairness, MA may be correct in saying they are "reject" cells. However, one should not assume that rejected material is bad material. Rejected material maybe 99% quality of accepted material, and no differences may be noticed in anything but specific bench tests.

Any manu process will have a failure/rejection rate. What is done with this scrap material is interesting. There is no reason why a manu can't classify grades of reject material and sell them as such wholesale. Its a common practice in many industries.

Outlet stores began as sellers as "reject" or surplus material. Lots of people still find good deals and qualty goods at outlet stores.
EG: I really like Le Creuset cookware, but its very expensive MSRP. I buy all my cookware as seconds at their outlet stores. For much of the products, you can not tell the diff from the firsts and seconds, and the few you can are usually due to minor cosmetic errors. However, they did fail QC as a first run material, and are not sold as such. I am very happy with all my seconds, and more happy with the 70% less I paid for it. I can promise you it makes no fraking difference in how the food comes out.
