This is definitely "a thing." I've had two MacBook Pros whose batteries swelled to where it bent the case open.

I try to make it a point to put my laptop through regular charge and discharge cycles, as result. As much as I love this 21:9 monitor, keeping it perpetually connected is definitely not the way to go.

Modern versions of macOS limit the max charge automatically don’t they? Or is this a hardware thing?

I definitely recall seeing a notification that it wasn’t charging my MBP to full because it has spent too much time connected to the charger.
