Tesla does their own with real world data. It’s a non-issue. Save the planet. Stop making excuses and get an EV.
"Save the planet, buy a car!"

Brings a tear to my eye.

> 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.

Hopefully, in coming years, we will see more practically designed EVs that are more affordable. A practical car doesn't need neck-snapping acceleration, every bell-and-whistle and room for a family of six with a dog. I'd like to believe that as batteries cost drop, the incentive to justify the extra cost will drop. Then we can get back to "just basic transportation" rather than a luxury product for the rich. While $31k isn't exactly cheap, the base new Leaf is heading the right direction.
81% of original capacity for many cars means when driving at highway speeds you will get like 250 miles or less range per charge. Still dramatically less than gas cars.

My old '07 Focus would get about 260 or so miles between visits to the gas station.

Important to note that this article is geared toward Fleet Managers, so terms like “average service life” may not apply. For example the average car in the us survives 12.6 years before being junked, totaled, etc. which is far longer than a car would be in fleet service at a company.
