It’s a common enough question, and one that really hasn’t had an answer … until recently, that is. Plug In America did a survey of several owners of Tesla’s Roadster, the precursor to Tesla’s hot-selling Model S sedan – and, arguably, the first successful modern electric car – and found that the cars’ batteries maintained 80-85% of their original capacity after 100,000 miles. 85% after 100,000 miles. That’s significantly better than even Tesla’s claims, which promised Roadster buyers that they’d retain 70% of their battery capacity after 5 years and 50,000 miles. It’s also worth noting that, in practice, mileage seems to be the only variable that impacted the Tesla’s retained battery capacity. Hot or cold climate variations don’t seem to play a role, neither does the type of driving (range vs. standard mode, for example). SO, while there still isn’t a direct answer to the “How long do electric car batteries last?” question, at least we can now say “Well over 100,000 miles without a huge drop in performance and range.” and back it up with real-world data ...

After analyzing anonymous charging data from 122 Roadsters—accounting for roughly five percent of the current road-going fleet—non-profit EV advocacy group Plug In America concluded that Roadster batteries should retain between 80 to 85 percent of their original capacity after 100,000 miles ...
