Nearly all cars I tried had SOH over 90%. The car I bought is from 2021 and has 94,9% battery health. Buy a 25€ OBD2-dongle and read it when you test-drive it. If the owner cared just a little, battery health is not a problem. Don’t let fossil disinformation scare you.





Here’s a study about battery health. Bottom line is, charging from 0% to 100% gives you 500 life cycles until it’s at 70% health. Charging from 20% to 70% gives you 6.000 life cycles. That’s is a huge difference and you should keep that in mind.
I don’t know how low temperatures affect battery health. But ask around, aren’t EVs super popular in Finland?
