I cannot disagree about being wary of Tesla . . I certainly am. Here's an article about data from 6,300 EV's from 12 manufactures. Also includes a cool graphing tool . . . https://electrek.co/2019/12/14/8-lessons-about-ev-battery-health-from-6300-electric-cars/ Graphing the data: https://storage.googleapis.com/geotab-sandbox/ev-battery-degradation/index.html

As for my own EV's . . I was an early adopter with the 24kWh Nissan Leaf - only had about 65 miles of "real world" range. Didn't keep that long and traded it for a VW eGolf . . . 125 "real world" miles. Had that for several years . . .but traded it early in 2023 for a VW ID4. With 300+ miles, I no longer think about range. None of them had/have more than 30,000 miles . . .and I never noticed any degradation at all. The impact of cold weather is a MUCH more more noticeable issue!!

I'm on my 3rd EV . . and none of them have been a Tesla. I am FAR from a Tesla/Musk fanboy . . .but they do release the exact data you are asking about. Here you go . . 12% degradation after 200,000 miles.

Roughly speaking, EV's lose range at a similar rate that ICE engines lose horsepower.

But a 10 year old Tesla is worth much more than a 10 year old BMW . . .

Here is a Nissan Leaf used as a taxi . . .100,000 miles with no noticeable battery degradation . . .

You replace the battery of an EV just about as often as you replace the engine block in an ICE car. Both do happen . . . but very, very infrequently.

That really should be cries in Englandland . . . I moved from Hertfordshire to Scotland 2 years ago (driving an EV all the way up the A1(M) . . . Chargeplace Scotland really works VERY well . . .
