Guys Trying to gauge the life expectancy of a Tesla battery. I have a 2012 S85 with 57k miles and i have seen about 5% degradation over 3 years. I am wondering how old is the oldest roadster? What capacity degradation do these older roadsters experience with mileage/time? If you don't feel like claculation the % degradation just mention how many rated miles at 90% or 100% and at what age? Thanks. If a thread exists on this subject, please point it out.
