Basically saying i3 batts should last up to 20 years with end of life charge up to 80% of original value (although latter years maybe for use as Solar PV storage units).
Says Tesla unit Lifespan dependant on use - if cold climate and gentle use - 20 years, if lots of aggressive acceleration in hot arizona desert, life might go down to 5 years.
