MacOS has a warning system that alerts you when the battery’s condition is becoming critical. Would it be possible that a battery starts swelling without detection from the system?
[Re-Titled By Moderator]
I had about three different MacBook Pros (Intel, very thin case 15" circa 2016 - 2019) where the battery swelled it distorted the case. They were all the same style of case. There were no battery warnings. Once I heard a couple of very loud cracks when the case expanded. I stopped using the laptop and disconnected from power each time before having the laptop replaced.
I noticed the swelling because the laptop's rubber feet weren't contacting a flat surface and the laptop would easily move. There was a significant bulge in the middle of the laptop which the laptop rested on rather than the rubber feet.
The M1 MacBook Pro is thicker and hasn't had this issue. I suspect the issue was related to a build up of heat and the M1 is cooler and thicker than the Intel MacBook Pro.
If you are concerned I'd let someone take a look at it.

Mac Battery Corroding:
Get this Serviced:
Swelling would indicate that the battery is corroding, and that makes this a health hazard. So, if corrosion is occurring, you should get this serviced, ASAP.
Contact Apple Support:
A. Contacting Apple Support:
B. Contacting an AASP:
Also, look into taking it to an AASP(Apple Authorized Service Provider) seeing if they offer service for this.
Can MacBook battery swelling go undetected by the warning system?
Yes.
Would it be possible that a battery starts swelling without detection from the system?
Yes.
Not sure. The critical battery health I have seen was not because the batter was dangerous or swollen, it was because it was 6 years old and not holding charge.
Probably best to check with Apple directly on this.
That doesn’t sound very good. Is there an explanation to why such things are not detected by system or software?
Since Apple (and others) takes risks with swollen batteries pretty seriously, it’s quite unbelievable that visual detection would be the only method to determine a battery failure. Letting it go that far may be already too late. 😨
So, does this mean that MacOs is not recognizing these kind of serious errors at all?
The reason is that such swelling is the result of a chemical process that cannot be determined electrically. Neither the system not its software can detect things like broken glass, worn or missing keys, scratched or dented cases... etc. Such physical phenomena require perception only sentient human beings possess.
