Ok so your first link. Goes to leaf forum. User replaced battery with a bigger one. Your second link. Texas takes batteries no longer suitable for car and makes grid. Neither of those is a decade old car running on its original battery. And I also said degrade which we know is true. What’s your point?

Your point is false. Batteries last long enough, there is no massive degradation at 10 years, and you have no data to prove that assertion. Whether you believe it or not, heh, that's up to you, believe what you want. Facts are facts.

(my 2018 Model S with ~150k miles on it has ~7-8% degradation after 8 years of aggressive use, the majority of charing done at fast DC Superchargers across the US; the only maintenance it has needed has been tires, wiper blades, wiper fluid, and a replacement battery pack heater to condition the pack for fast DC charging, which has been obsoleted in newer revisions)

  > Yes because everyone wants a massive EV with a degraded 10 year old battery I said batteries are degraded at 10 years old. Your 8 year old car is 7% degraded. How is my point false? And to quote you > We generally see 1-2% range degradation per year.

    You believe the degradation is material, all of the evidence says that it is not. I suppose we agree to disagree then. I don't have strong feelings on the topic, if folks want to keep paying for fossil fuels at these prices, or higher prices, versus driving an electric vehicle, good luck to them. That's a choice. Natural consequences are important to encourage better outcomes.

      The evidence you showed like a leaf owner swapping for a bigger battery? 10% degradation is material and noticeable.

        My citations specifically speak to your example as being no longer relevant due to state of the art battery pack management. Please read them again. No one builds air cooled battery packs like the leaf had that were highly prone to failure. Battery pack architecture and management operations have continually been improved over the last two decades to improve longevity.
