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.

EV Batteries Are Defying Expectations After Hundreds of Thousands of Miles - https://www.wsj.com/business/autos/ev-batteries-are-defying-... | https://archive.today/2RFo3 - July 4th, 2026

> Industry experts think newfound knowledge of battery durability is a game-changer for consumer confidence in EVs

> Richard Symons recently took his five-year-old Tesla Model 3 on a 260-mile road trip across England without having to stop for a charge.

> A new electric vehicle could make the trip no-problem. But Symons’s car—which he has affectionately nicknamed “Miles”—has logged 247,000 miles and is still up for frequent long-distance drives. “They are proving themselves to be exceptionally reliable,” Symons said.

> After five years on the road, the average EV will still be able to drive up to 95% of its original range, according to Recurrent, a data-science company that provides a battery-monitoring tool for EVs—better than many in the auto industry expected.

> When early EVs hit the market, buyers’ concerns were well-founded. Roughly one in 12 EVs built from 2011 to 2016 have had to have battery replacements. But new data shows that more modern EVs are doing better so far. Among EVs built from 2022 on, 0.3% have had battery replacements, according to a 2025 study from Recurrent.

EV Battery Health after 250 Million Electric Car Miles - https://www.recurrentauto.com/research/lessons-in-electric-c... - May 17th, 2023

> 250 million is a lot. That’s how many miles Recurrent vehicles have driven since they connected to our services to monitor their EV performance and health. There are some optimistic, high level takeaways in all this data. For most EVs, the lithium ion batteries are in quite good shape and only 1.5% have been replaced in Recurrent's community of 15,000 cars. Battery replacements due to excessive degradation are very rare. Heat, high voltage, and extreme state of charge degrade batteries the fastest. We generally see 1-2% range degradation per year.

(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.
