Age is going to be more of a problem for EV batteries than mileage. I’ve seen enough reports of cars doing 200k miles inside 9 years without any issues.
Hydrogen Vs BEV cars.

Although having said that if batteries are warrantied to 8/10 years they should be engineered to be useful for at near double that as the warranty expiration should sit in the middle of a bathtub curve.
That may depend on what the definition of "useful" is. There are many of the much-maligned Nissan Leafs driving around with 60 miles of range after 12 years. That range may still be useful to the person driving it if they do less than 60 miles a day.
And you think the battery tech used in a Leaf is similar to modern batteries and BMS in the current batch of EV's?
[Shakes head]
We are 15 years in to mainstream EV usage, look at the progress in technology and development of capabilities compared to a ford model T to an Austin 7 over a similar period at the start of ICE development
I don't. No idea where you got that idea. I posted earlier about how poor their battery chemistry was.

Going back to hydrogen, one of the true believers is starting to have doubts (but produces more than twice as many cars as the entire car industry in Germany so it can afford to keep running a hydrogen R&D project for as long as it wants).

After selling just 27,500 hydrogen cars [since the Mirai launch in 2014]...“I can’t say for sure that it’s a bright future for hydrogen,” Hiroki Nakajima, chief technology officer at Toyota, told reporters at the Fuji Speedway racetrack in Japan in November....
“On all levels, hydrogen has been a failure for passenger cars,” said James Hong, head of Asia energy transition and commodities at Macquarie Capital. “Where we still haven’t got an answer yet is on commercial vehicle or stationary energy storage demand.”...
A hydrogen version of Toyota’s upmarket Crown car model costs ¥1mn ($6,500) more than one equipped with a new hybrid system.....
Hyundai made a loss of Won30mn ($22,000) on every unit of its flagship hydrogen Nexo SUV, despite receiving Won36mn in government subsidies on each vehicle....
A lack of fuelling infrastructure in Japan and abroad remains an issue. Oil major Shell announced last February that it would shut all of its hydrogen refuelling stations in California, the state where fuel cells are most popular in the US. In response, Mirai owners filed a class-action lawsuit against the company in July for misleading them on the availability of hydrogen fuel....
Despite the setbacks, Toyota insiders said they had not given up on hydrogen for passenger cars, with Toyoda discussing a partnership last October with his counterpart at traditional rival Hyundai to advance fuel cell vehicles.
Meanwhile, Toyota are spending $13.9bn on a new battery factory in the US. Follow the money...

They should have rung me, I could have told them that two years ago. I am probably on here somewhere saying pretty much the same.

Another announcement snuck out before Christmas was that Hyzon was pulling the plug - they had been one of the first to produce a commercial hydrogen truck, with a particular focus on bin lorries :

May 2023 I think?

In my case 2020 (and earlier than that elsewhere)

BMW has announced a move away from electric vehicles, stating that it has successfully addressed the challenges of hydrogen engine technology.
The company revealed significant progress in hydrogen fuel cell development, which it sees as a more sustainable alternative to conventional electric cars.
Unlike electric vehicles that depend on large batteries, hydrogen engines use lightweight fuel cells, offering faster refuelling and greater range.
BMW also emphasized the environmental benefits, highlighting that hydrogen-powered vehicles emit only water vapor, making them a promising solution for the future of eco-friendly transportation.

I know I'm repeating others (and myself), people still seem to think of hydrogen like the gas that powers their boilers and the air we breathe....it's not. It's horribly reactive stuff that leaks through solid hardened steel, and damages everything it comes into contact with.
I do though think it may have a niche for energy storage over the short term, where renewable energy is plentiful but intermittent. It does irk that electricity in Orkney costs the same as elsewhere but we regularly have to turn off the turbines because the export cables can't cope with how much is being produced. Anyway while we don't have any mains gas up here, we oddly do have a hydrogen gas refuelling station near the Kirkwall harbour... I've no idea who uses it though!
