The auto enthusiasts at the YouTube channel Out of Spec Reviews say they’ve found a Tesla Model X that possesses an impressive 200,000 miles while only losing 10 percent of its battery capacity which is not bad at all.
The owner of the Model X, a silver 2017 100D, told Out of Spec that between 60 to 80 percent of the time he charges the vehicle at Superchargers.
When the owner first bought the car, it had an available battery capacity of 93.7 kWh. It has been five years and 200,000 miles since then. The Model X only had a battery degradation of 9.8 percent, according to its app. That means a resulting battery capacity of roughly 84 kWh.
Claims of this EV’s battery health are in line with Tesla’s own findings on its Model S and Model X cars. Interestingly, a third-party study that used self-reported data from Model S owners found similar results: that Tesla batteries retain 90 percent of their original capacity after 200,000 miles.
Sounds like good news for Tesla and EV owners.
