Oh there's no way in hell I'm doing it to modern cars. This was on some lancer shit box decades ago with silly gauges that started beeping when the voltage was outside of operating range -
Not just stop start. New modern cars with their stupid "smart" alternators. Even funnier is watching cars when you drop them into eco mode. A lot of them don't crank the alternator up to full charge for very long at all. EVs and how they charge their 12V lead acid battery is even worse! Also, you should never disconnect the battery, on a running car. The voltage spikes can break things. Basically while it's a "battery" it is also considered a "Capacitor" within the charging system, and helps to keep those spikes non existent. Yay for alternators being inductive. -
I could probably pull a few logs out of the servers at work, would show it happening a lot. My job is in vehicle telematics, and I spend more hours than I'd like in data analysis/review for various reasons.

On cold start cranks, you can tell the starter motor isn't as "crisp" sounding. Especially cars with stop/start "technology" (not really technology, it's garbage). Test was done at Supercheap Auto, it's part of their warranty claim process. Not often a good definitive test, as the battery may still show a "healthy" voltage - like mine, in the test you can see it's showing 12.41V I've seen this too, when you jump start a car with a completely fried battery, just as bad as when you disconnect the battery terminal on a running car and see the voltage spike LOL -

Can't remember the last time I saw a good, healthy battery dropping into the 9s during cranking, Too many variables to say anything about it with any certainty though. A float voltage of 12-12.2 is tired AF and given how AGMs handle high C rate and DOD, will just die faster and faster with each cold start.
