Intel-only Macbook (OSX) limit maximum battery charge using SMC

Project mention: Apple's new 80% battery limit feature should not be limited to the iPhone 15 | news.ycombinator.com | 2023-10-18

That's true. I evaluated it, but it wasn't of use to me as I keep my Macbook plugged in with the lid closed.
I eventually tried this instead :

I use it to keep my battery level indicator pegged at 70%. Often doesn't persist after a system update, but it's just a quick terminal command to reapply the setting.
I use my Macbook in clamshell mode, and I use sleep mode when I'm not using it - receiving power from a Thunderbolt dock. It's handy to pick up exactly where I left off on resume. Plus, I use two LG screens where one of the two doesn't switch on after a cold boot, and it's annoying to unplug and replug to activate it. Sleep mode gets around that.

Project mention: Battery life of suspended Acer Aspire laptop | /r/Ubuntu | 2023-06-10

I believe that the BIOS controls battery charging. There's an option to limit battery charging to 80%. I didn't find it in the BIOS but you can permanently set it in either - Acer Care Center under Windows or - https://github.com/frederik-h/acer-wmi-battery under Linux
