Yes about 10 years if you only need to charge it twice a week. I think it depends on where you live, a guy on YouTube lives in the mountains of Idaho and especially in winter his driving range gets cut to less than 100 miles in his Tesla. Some batteries are not as good when it's freezing outside. Also, where he lives the speed limit is 80 mph and the estimated ranges are for cars driving like 55mph. They can be a great short range commuter car in a flat and moderate climate, otherwise I think a hybrid makes a better solution.

A lithium battery is normally good for about 1000 charges at normal rates. I wonder how much of their lifespan gets cut with these superchargers. 750 charges maybe.
