Sure, but my point is that you have gasoline being produced by many companies and production facilities, from many different/blended inputs (heavy oil with low gravity, NGLs, ethanol mixture, et al), and with proprietary additions.
There's no reason that batteries can't be checked that the meet spec before they are replaced in your car in the same way.
- jstarfish 8y agoI'd be surprised if each battery couldn't come with a little computer that tracks charge times, cycles and power output over time. It would make it trivial to monitor whether or not a battery is currently serviceable (or whether it will expire prematurely). For EV fleets we used to only be able to do this per vehicle (not by battery) while the vehicle was home and charging, by shipping the fleet battery metrics to a central aggregator. But that is overkill for consumer vehicles.

Tesla knows better than you ever possibly could as to how well each and every cell in your battery packs is doing.
