I visited the Tesla showroom
I visited the Tesla showroom twice in the last month and had conflicting answers by two different sales people. One sales person told me the S battery was a Panasonic battery and the other sales person told me the battery for the S was an A123 battery. Then, when I asked how long the battery life was I was told it was 10 years. Electric battery life should be based on cycles, not years. I have looked at a lot of electric vehicles and own one and own three hybrids. When I asked how much a replacement battery would cost she told me $12,000 for the premiere S and that would give me a 300 mile range on a charge and that Elon Musk had even tweeted recently that one owner claimed he got over 400 miles on one charge.. I asked if I bought an S could I get a written guarantee that I could buy a replacement battery in the future for $12,000 and she said NO. I wish reporters would check out how Tesla can get over 400 miles on a charge when comparable batteries for that price can only get 30 miles at most. Tesla should come clean with their battery claims and how it can get mileage at those prices when the competition can't. Tesla is not the only electric manufacturer that uses Panasonic or A123. And, none of the other manufacturers make such an outlandish claim. I think that if you order an S, get your battery replacement prices in writing.
