Because of the limited range, people would cycle the battery almost daily, and people would charge to 100% if possible.
If you charge it daily and you get 2000 cycles out of it, you might get 5 years of life
If you have a larger battery and charge it weekly (same 2000 cycles), you get 38 years out of it.
You could do this calculation with battery range vs car mileage too. This also doesn't take into account range degradation.
