The big question with any battery replacement is what the core credit is for the expended battery. If the battery costs $20k, but you get an $18k credit for surrendering the used battery, then it's not so bad. In theory, used car batteries would still be in fine shape to be used in fixed systems (like a whole-house battery, etc.) thus generating a nice core credit, but there just isn't enough data to know what that will look like in 10 years.

I'm sure there's value in recycling the various exotic materials they're made of, but I don't see how that would be anywhere near 90% of the original value
