Actually, you'll probably never need to change the battery as "the latest data shows less than 10% degradation of the energy capacity after over 160,000 miles on Tesla’s battery packs" [0]. Even if it degrades like 50% by the time the rest of the car dies, there will probably start to emerge a market for the old batteries to use them for grid storage where kwh/weight does not matter as much so you might even get some of your money back.
