Electric vehicle batteries are a hot topic but their longevity can be impressive.
According to the auto enthusiasts at Out of Spec Reviews, they tracked down a Model X that had 200,000 miles on it and only lost 10% of its battery capacity. It's not terrible.
The owner of the Model X told Out of Spec that between 60 to 80 percent of the time he charges the vehicle at Superchargers, a method that's sometimes speculated to be worse for the EV battery as opposed to charging it more slowly at home. The battery seemed to have held up well.
The Model X had a battery capacity of 93.7 kWh when it was first purchased. A battery capacity of 84 kWh is the result.
If the car continues to hold up, it will be comparable to modern gas vehicles.
This may be a single anecdote. The claims of this EV's battery health are in line with those of the Model S and Model X. A third party study used data from Model S owners to show that the batteries retain 90 percent of their original capacity.
It sounds like good news for electric vehicles. It looks like the batteries have a decent mileage, but beware that their warranties aren't often very solid, and that replacing them well set you back.
The family is annoyed when replacement batteries cost more than the electric car.
