Sure, but I'm not pointing out the longevity of the batteries, but rather the maintenance cost if/when they fault. I understand it will get better over time as technology improves, but it's been a large impediment to me (and probably others) from investing in them.
Here's a recent synopsis that suggests 50% of the car value on average back in 2020 [1].
A 250,000 mile car is worth scrap value whether it's gasoline or electric.
A battery failure and a timing chain break or other types of complete engine failure before that mileage are comparable concerns -- similar rate of occurrence and similar cost to fix.
Battery costs are continually declining. If you buy an EV today, and then if you need to replace the battery in 15 years, because you put 300,000 miles on it, it won't break the bank.
