notebook is a 10 year old macbook pro without macos I installed xubuntu 24.04 in. It comes with an embedded battery.
First notebook I bought, not from apple, had a removable battery. The vendor told me to maximize its life I shouldn’t plug the battery in, unless I need it (like for traveling). This way, I’ve managed to keep the original battery in good working condition for 8 years so far.
Back to the macbook: I cannot remove the battery and constantly loading it to up to 80% and discharge it up to 20% seems ridiculous. Furthermore, this would deplete the battery even faster, I believe.
What can I do to spare the battery as much as possible?

The most important part with batteries is to check if they start swelling up.
do you mean physically swell up? like I’m going to see it bent/bigger?

For linux it depends. For example, you can modify the maximum charge on ASUS laptops. There’s also this wonderful tool called asusctl [https://asus-linux.org/] that modifies allows you to more effectively use your laptop. Here is the arch wiki page for it: https://wiki.archlinux.org/title/ASUS_Linux . Do note that, unfortunately, the only officially supported distros are Arch and Fedora, but you can make it work with some effort.
TLP is my favourite tool for messing with the charge limit. And also far, far too many power/thermal management knobs.
As long as it is still running you should be fine, but it’s better to keep your battery around 80%. There are tools that block the charge until you ask for a full charge when needed
My son has a gaming laptop that is plugged in constantly. I vaguely remember reading that all modern laptops protect the battery to some degree, though not sure how. I’m guessing it is by using the mains while charging. Not sure what the damage is to a battery that is constantly fully charged.
After reading this thread I hope this is true I have had 2 laptops plugged in one for like 5 years non stop (this one I deactivated the battery in BIOS it’s old) and the other for about a year…
You could try to uninstall the battery and just put an AC cable in. My laptop works like that.
just to be clear, you mean removing the battery, or do you mean using a command?
Yeah just physically opening the case and unplugging the battery. Idk, I just read MacBook Pro, I never had a Mac because I hate the company partly because of their non-repairability, so maybe you can’t even take the battery out without dissolving some glue or some shit. For all the laptops I had so far, it was just unscrewing some screws and then you can unscrew/unplug/replace the components within.
