Yes that's exactly what I'm suggesting. The two things I never had to replace since I got my first laptop in the late 90s, not do I know anyone who had to replace those.
The screen can be understood, screens just work, and without physical damage, they keep working.
But the battery degrades even if it is not being used. For whatever reason, you are misinforming people here.
Literally the battery is the only thing I had to replace on every laptop I've had.
