TL;DR Most EV batteries will last longer than the cars they’re in. Battery degradation is at better (meaning: lower) rates than expected. Slow charging is better. Drive EV and don’t worry about your battery.
„Our 2025 analysis of over 22,700 electric vehicles, covering 21 different vehicle models, confirms that overall, modern EV batteries are robust and built to last beyond a typical vehicle’s service life.“
EV Battery Health: Key Findings from 22,700 Vehicle Data Analysis | Geotab
Analysis of electric vehicle battery health of 22K+ EVs reveals a 2.3% average battery degradation rate. High-power DC fast charging is the top risk factor.

Good news…

@bob_zim I think I do recall that, actually, but to be fair, anyone who ever tried to keep a ghetto blaster going on NiMH D-cells knows that was doomed from the start.
@jpaskaruk @bob_zim @jwildeboer my boomnox had 8 and drained them pretty fast. Lol

@dalias many newer cars manufactured in the past 20+ years will not make it to 25 years due to electronics failing (capacitors and mosfets are typical candidates), regardless of being powered by ICE or EV.
@jwildeboer See: "atrociously bad quality of cars". This wouldn't be a problem if swapping out the electronics were trivial, but when you have an intentionally locked-down shit Android device on wheels rather than a proper car...

@jwildeboer What about cold days? We recently had about 3 weeks around -40, usually get about 2 weeks a year below -30 C and months of -20 C. In this climate, must people don't have a garage, and those who do generally don't heat them. Any insight?

@jwildeboer yes. Data doesn't go that far.
@renard @jwildeboer battery degradation slows down over the lifetime. Although this probably depends on the chemistry.
BEVs typically have lower maintenance, so I don't see why 20yr can't be matched. If (e.g.) 70% State-of-Health is acceptable 20-years in, i guess it's still a viable car to drive.
However, I'm not sure why "20 years" is a metric to hold up against. Is that primarily a financial consideration? Worded differently: Would you buy younger for the same price?
