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?

    this is what sudo tlp-stat -b prints:

    Charge = 97.9 [%]

    Capacity = 79.7 [%]

    do you still recommend a new battery?

      nah you got about 400 more cycles at least.

      keep it plugged in whenever you can to make it last longer.
