Wow that be niceI agree if they warrenty 70% useable they probably expect 85%.
Just for a little more information on my usage.
6% of that degradation was 1st 2 years
4% was last 3 years.
I’m guessing the lower degradation rate is a product of OTA updates tweaking the battery management System.
When I purchased the car in 2016 Tesla was doing 8 years unlimited mileage warrenty for the battery and drive train.
With unlimited supercharging
