A $25,000 used EV with 80,000 miles is not a good deal if you're going to have to spend $20,000 to replace the battery.

If you can get another 150,000 miles out of it with almost no maintenance or repair costs, it's a screaming good deal.

The latter is far more likely than the former, but people don't realize it yet.

P. S. I will likely be buying a used EV soon.

What makes you think that you would have to do that?

1) that car would still be under warranty until it is older than eight years or drives more than 100K miles. So if it needs a replacement at 80K miles, you might get it for free because it's not supposed to fail.

2) There's a lot of data that suggests batteries last a lot longer than their warranty period both in miles and years. There are plenty of EVs with 150K or more miles on them that are still fine. And define fine, is it such a bad deal when the battery has 75% of its original capacity instead of 85%?

3) It's hard to get numbers on when they actually do fail on average for the simple reason that the overwhelmingly large majority of EVs ever made are still driving around with the original battery they left the factory with. They've only been on the market for about 15 years. And the majority of them is much younger than the eight years of battery warranty they left the factory with. Most of the EVs on the road have been sold in the last few years only.

Sorry, my original post was originally formatted correctly. Some readers are reading the inverse what I was trying to say. The link shows that EV's are lasting up to 300,000 kilometers on a single battery.

I'm going to buy a used EV, and I don't expect to replace the battery.

But why spend $45,000 on a used EV when you can get a new one for the same price or less?

I'm not, I'm going to spend ~$20,000 and I expect to save many thousands over the next 10 years in reduced maintenance compared to my ICE vehicle.

Edit: Oh I see the confusion. I should have been more explicit in my original comment that the second case involved not ever replacing the battery.

Ah, yes that does make sense now. Thanks for explaining.
