Agreeing with you wholeheartedly. TESLA's reported battery life (I never kept any car this long):True, the lifespan of battery systems is much longer than ICE vehicles from everything I've read.
300,000-500,000 miles
Tesla car batteries are said to be designed to last 300,000-500,000 miles (as purported by Tesla CEO Elon Musk), or about 21-35 years, based on the average amount of miles driven by Americans in one year, which is typically around 14,263.
