Hi everyone, Brand new owner of a rear wheel drive Model S 85. I will be using the car 5 days out of the week to commute to my work (50 miles to work, 50 miles to home), mostly driving on Southern California freeways from LA to the Inland Empire (can't wait to use the HOV lane!). After picking up the car yesterday at the Service Center, we were given the recommendation to keep the battery charged to 90% (the exception being long road trips), however after browsing this forum, I'm wondering if I should set it to a different limit. Obviously I will know more about the car's performance once I start regularly commuting to work (I tend to drive over the speed limit whenever possible, going 80-85 MPH as my commute is largely "against traffic"), but I was wondering with my daily 100 mile commute, what would experienced owners recommend in terms of my battery settings? Obviously as I am really going to be putting a lot of miles on this car I'd like to maximize the life and performance of the battery for as long as possible. On a final note, I've really enjoyed lurking in this forum and thanks to everyone for sharing their thoughts on how to make this incredible car even better.
