You misunderstand me. I'm saying that unlike ice vehicles that will continue to get about the same mpg for the life of the vehicle, lithium batteries degrade with every charge/discharge cycle. When an electric is new and you buy one with enough range to suit your needs, every year you own it the max range on a full charge is reduced. So an ev with 120,000 miles on it that started off being able to go 300 miles max will now only go about 250 miles max. The batteries lose capacity. The federally required 8 year 100k mile warranty on batteries only covers if the capacity of the battery is less than 70% of the original capacity. Typically though, evs are usually in the range of 80 to 90% capacity at the 100k point. They don't start dropping off hard until they're closer to around 200k and over 10 years old most of the time. Total failure due to dead shorts in too many cells has been happening around the 14 to 18 year area. That's when you decide to sell it for $3,000 or pay $15,000 to install another battery.
