It is because cycles is really the only thing they can simulate reliably and it also sells vs saying 1000000 miles if you drive 100 miles every day, 200000 if you drive 20 miles a day, 50000 if you drive it once a month etc.Heat doesnt help though, batteries with active heating and cooling will live longer, I'm sure. As for chemical degradation over time, I think we cant cross Priii lifespan with lithium-ion. I know that in life support equipment, LI-ION has much longer storage lifespan than NI-MH. Doesnt make much sense to say the batteries are good for 300-500 thousand miles (1,500 charge-discharge cycles) if they die for other reasons long before the average driver will get to those miles. At 15,000 miles a year, thats a 20 year lifespan for 300,000 miles.
Oil I. You car lasts 5000 miles, if driven regularly but do you ever see it advertised if you let it set for months at a time?
