Why remove the battery when it is a perfectly working built in UPS?
Because over time the battery degrades, swells, and becomes a fire risk.
Keeping it only 80% charged can help mitigate it but not fully.
That is largely a myth and in my experience never happens with higher quality laptop batteries. But yes limiting charge doesn't hurt if it is only used as a UPS anyways.
What part is the myth?
Which batteries are "high quality"?
Cause it happens... Pretty regularly if you're not limiting charging. The older the battery the more likely.
This isn't something you should fuck around with either: if it pops it'll burn too hot to extinguish and could take out your house.
Not a myth. Better batteries might have better safety measures, but none is inmune. It might not have happened to you but I've seen it happen in several high end/expensive brands already.
Happened to my ladyfriend with a macbook pro. Cracked the shell of the laptop. No fire, but it sure did swell.
It will be a really bad UPS at best
Because it is a safety issue and the battery isn't designed for that anyway. A UPS is designed to stay charged for a long period of time and laptop is not.
