I mean, the headline does say 20 years soooo…

Also, Teslas are approaching 10 years old and as far as I know their batteries are still going strong (yes, I know their quality control is otherwise sketchy). The Nissan Leaf batteries are getting pretty sketchy, but they don’t have any battery conditioning - just air-cooled. That’s not doing longevity any favors. All other major EVs have battery management systems and seem to be holding up ok. They’re also generally warranted for 8 years. I don’t think they’d only have a 2-year buffer between warranty and expected life.
