This is the way

Otoh, a family member gave me their “broken” Asus zenbook, I replaced the battery and its been running great for a few years now. I’m at the point where I need to replace the battery again(and maybe ditch Ubuntu, I always regret installing it)

Not that tbjs necessarily helps you but the battery in switch pro contolers was really easy to replace, spent like 5$ getting new ones from Ali express. Maybe try looking it up?
