I'm surprised modern car electronics do not already allow this like
they tend to do on Lithium cells these days.

Given there's nothing you can do about a faulty cell in a car battery, not
much point?


As we used to say in industrial automation

"Never check for an error condition you can't handle"

Good advice.

It is a sound reason to replace a battery if you are not sure whether to do
so.
