Tesla Loss Of Battery Range Less Than Feared
Research from Plug In America and others shows Tesla owners don’t need to be overly concerned about battery loss. In 2013, PIA did a study of Tesla Roadster battery longevity using data from 126 Roadsters driven a total 3.2 million miles. The study concluded that the typical Roadster would still have 80-85 percent battery capacity after 100,000 miles (though some Roadster owners have lost much more ). The Model S has a superior battery management system to the one found on the Roadster, so it stands to reason that battery degradation should be even less.
