"Tesla says 300k out of a battery". This doesn't jive with my experience using lithium batteries for various devices. The batteries usually start loosing capacity after a year or two, or roughly 500 charges. That's using a proper stand-alone charger. Tesla may have some tech advantage but last I saw it was just a big bank of 18650 cells.

Tesla’s advantage is huge, just not visible yet, they have put the work and research into going away from others for their battery supplies and creating a process where it is much more cheap and efficient to produce those batteries. They are investing tons in creating everything from the ground floor including the equipment used to make the batteries. We will see this become much more visible when their battery factories go online over the next few years.
