    Fascinating stuff from the CHAdeMo/SAE-QC support thread on the design intent behind the lifetime for the Model S battery packs!

    That's very interesting indeed. You could say that after 18 years, the 85kWh pack has roughly the equivalent range of a 60kWh pack. Likewise, after 18 years, the 60kWh pack has roughly the equivalent range of a 40kWh pack.

    So one could conclude that battery-related depreciation cost of the Model S is only $10,000 over 18 years (the cost difference between a pack size). That's $46 a month.

    That's almost definitely a misquote (mishearing 8 years as 18 years or a typo).

    Here's what Tesla officially says:
    http://www.teslamotors.com/en_HK/models/faq

    There's a good point on that thread, which is that the Roadster and Model S's active cooling (which keeps battery temperatures near the optimal temperature that the cells are tested at) means there should be little to no difference in battery degradation based on the ambient temperature of your location. For example, you won't see the large difference in degradation seen in the Leafs in Texas and Arizona. The cost is of course a slight hit to efficiency.

    I don't remember language like that ever being on the Facts page.

    Well, if it's 30% loss over 7 years (as per en_HK faq), then the math is a $119 monthly depreciation in value due to the battery degradation.
