I agree it's terrible; even from TFA's opening paragraph:

> if electric utilities were to pay $15,000 per battery, the battery alone in a 10-year-old Tesla would retain more value than an entire vehicle powered by an internal combustion engine (ICE).

a) why would a utility pay that much ($2.2/cell) for a bunch of heavily-used 18650s when you can buy lightly-used 18650s on eBay today cheaper?

b) if you look up used 2007 Mercedes S550 for sale in the US, you'll see plenty that sell for $15k+.

a) surprise. Those "lightly used" cells aren't lightly used. Have you ever bought them? Cheap eBay cells are garbage.

Sure, I've bought a few, and my experience is "used LG/Panasonic/etc 18650s" are about as good as "new Ultrafire/TrustFire/etc. 18650s"
