> How long do electric car batteries last?
The article never answers the question. But if you assume 70% end-of-life threshold with 2.3% loss per year - then we're looking at 13 years.

We’ve noticed after 6 years out Tesla, the battery seems to charge slower than it used to, but otherwise all is well. I just love the convenience of charging at home, gas stations seem so odd and antiquated now.
I myself have a 11 year old Nissan Leaf with pretty significant battery degradation (the guessometer says 70 mi range but I wouldn't count on more than 35-40) and it's fine for probably 95% of my driving.
If I were to buy an electric car with 300-350 miles of range today, I could easily see myself finding a ton of value in it in 20 or even 30 years. It's still more range than my current one! Lol.
"When the battery degrades to a certain point, for instance, if a battery can only retain 80% of its initial capacity,9, 10, 11 the battery should be retired to ensure the safety and reliability of the battery-powered systems."
