Has anyone heard how long (milage or years) the battery is supposed to last before needing replacement in the energi and what the estimated cost would be? When I was considering a Tesla last year, they said the battery life was about 1000,000 miles and the cost to replace the larger battery in the Model S was around $30k but you could buy one at the same time as you purchased the car for about half of that and then get it installed when needed. I drive about 30,000+/- miles a year so replacing the battery on top off the price of the car in the first five years is something I am concerned about. Thanks for any info you all might have heard.
