Will Cars Get Better Battery Life Soon?

Episode 1792 (2:00:30)

George from Santa Monica, CA
Tesla 

George keeps hearing about new Tesla car battery technology that promises a million miles before replacing. Leo says he'll believe it when he sees it. There are always stories about new battery technologies that promise great things but are short on delivering. However, the battery capacity is getting better every year and the range is improving as well, so he may have to charge less often, and when he does, it'll be faster to recharge.

But a million-mile battery? Not likely.
