Ok, no problem. Please state the "life of the vehicle" that you mention in miles driven and years of ownership. Also state whether this figure is backed in a legally binding warranty on said batteries. Then we'll figure the cost of maintaining the batteries.
Also, to be fair, we should note that the tesla.com link you give is to a program they are hoping to implement in the future and which does not actually exist in real life. Also note that they themselves in the link which you yourself provided state "Aside from the cells, most components in our ESS are designed to last the life of the car." Note the "aside from the cells". The lithium cells are the main cost of the battery. Without them the car does not work. Tesla specifically states there that the cells are not designed to last the life of the vehicle, which you had claimed.
Thanks very much for that. So according to tesla's latest information at that link, the program doesn't actually pay money back as was claimed, but it also doesn't cost anything to dispose. It also states that 7 years or 160,000km (99,400 miles) is the expected typical life of the battery. 99,400/7 = 14,200 miles per year, expected usage, about 60 miles a day for 250 work days.
Haven't found the warranty information though which will tell us the real expected life for the Sedan. For the Roadsters, they come with a 3 year/36,000 mile warranty, but that does not include a battery replacement warranty, which is an additional purchase.
Musk stated in 2009 that a single battery pack replacement for the Roadster would cost $36,000 in 2009 dollars, but it seems to be something that wasn't actually available yet. (http://www.autoobserver.com/2009/02/tesla-battery-pack-repla...) There he also explains that the battery pseudo-warranty costs $12,000 extra. The inverse pro-rated pseudo-warranty is structured so that customers have to pay an additional fee if the battery fails before 7 years, and get a partial refund if they last more than 7 years.
