Speaking of laptop batteries as a UPS source, some laptops come with battery management features that keep the battery healthy even when plugged in full time, usually exposed as a setting in the BIOS/UEFI. I've found that business/enterprise type laptops like Thinkpads and Probooks have this as standard, for example Thinkpads from 2010 already had this, assuming you're lucky enough to find one with a usable battery of course.

Macbooks do this as well automatically if kept plugged in for a certain period of time.

  Is there something for Linux/debian? I’m assuming this is part of the OS and wouldn’t work on a MacBook with Linux.

    It's managed by the OS when it's awake, by the bios (or uefi or whatever) when it's sleeping. Both methods work under Asahi Linux on the ARM macs.
