Plug In America's Tesla Roadster Battery Survey
The first Tesla Roadsters were delivered to customers in 2008. These vehicles represent the largest body of high mileage electric vehicles to date. How are the battery packs holding up? How does energy capacity vary between vehicles? How much capacity loss is typical over time and distance driven? Do charging habits affect battery longevity? Do cars in hot or cold climates differ in battery health?
Plug In America has launched a survey to help answer these types of questions. If you are a Tesla Roadster owner, please share your experience with us.
