Thanks Tesla for bringing about lithium battery health awareness to the masses. Without it I would be charging to 100 every night. And blowing out my battery way too soon.

Arguably, it’s a misfeature of Teslas. My BMW i3 has a hard charging cap of 90%. (The UI scales the charge percentage and displays 100% between 90 and 100%) It’ll regen charge up to “really” 100%, but that would require something like a 5,000-10,000 ft continuous elevation drop, where you just ride the regeneration brake the whole way down. Nissan took a different approach. The batteries on the old Leafs died really prematurely because they didn’t have decent battery management. They fixed it on later models. Anyway, this stuff is mostly a solved problem these days. It would be nice if device manufacturers were compelled to provide an 8 year, 80% capacity parts and labor warranty on all non-replaceable batteries (like the car manufacturers do in the US).

It's very different when you are dealing with a $1000 object versus a $40000 object, where the replacement of the battery could cost $300 and $20000 respectively.

  Are we talking about phones and cars here? What phone costs $300 for a new battery? I assumed Apple would be on the high end, and they charge a fraction of this ($100ish, IIRC).

    That was only an example. My argument is only strengthened when you use the actual cost of battery replacement.

      Gotcha — just making sure I wasn't missing the comparison.
