No they aren’t. They degrade before they fail. If tesla wanted to provide a warning of a failing battery that pretty much always worked it could have wired in a load test and went off voltage drop under a heavier load.
Testing if batteries are good or bad does not qualify a person to chart out battery degradation.
Once again, I did this for a living, for a decade. We would constantly have cars with failed batteries, we would bring them in, charge them up, test them, they would pass, we’d send them on their way, and they would fail again
I also test batteries and this just looks like you all didn’t test them well. Like you skipped the capacity test because it takes being hooked up for a long time instead of the test that takes 20 seconds to do.
