I used three batteries on that particular MacBook and it always shown a "! Service Battery" warning before things went bad. The battery life, and shape of the battery was indicative of anything, either.
Oh, don't bring up SMART. I remember long-testing >100 disks, and most of them passed (it took hours), and all of them failed within 10 days after facing real workloads. We needed a temporary storage for migrating things, but we lost no data, because it was just a copy operation.
That may or may not be noteworthy. Despite half my family using MacBooks, and some having had major battery problems, I’ve never heard of such a notification as you describe (including at least one where I’d certainly have expected to hear about it). And the similar system SMART for storage devices is notoriously unreliable: I’ve personally had devices with dire warnings chug along merrily for plenty more years, and observed one or two failures that never received any warnings.
