I hear about eight to to ten years for need to replace them. So what happens if you get a bad ones?
Like I said water is free unless it comes in clear plastic bottles.But what is considered end of life. 50% of original capacity, 33%, or when they will no longer move the vehicle on flat ground? Also think about the resale value of a 7 year old EV. Who's going to want to pay for a car then know they will be replacing the battery pack in a year or two.
