I was watching several youtube videos last night on this very topic. Historically and on average EV batteries when charged properly tend to last about 8 years or longer while still holding about 70% of their rated capacity. The only exception to this seems to be the Nissan Leaf as they don't use any form of cooling on those batteries. Ford new what they were doing when they setup that warranty with the 70% capacity escape clause. They also mentioned that short charging helps to keep the batteries healthier than deep discharges followed by stage 3 DC high energy charging.Thank you ChasingCoral for the reply. I asked the Sales Manager (where I have the reservation thru) from the Grove City, PA dealership and he replied:
we don't have a data yet but we are looking at a range 15k to 20k for those batteries. Let me know if you have any questions.
