Fundamentally true of everything with a battery. For old Nintendo devices that just… hold on to that charge forever I also strongly recommend pulling them out of mothballs every year or six months and giving them a full charge cycle, just in case. Gives you a reason to revisit old games, while you’re at it.

I wanna say they did the foam thing on Switch 1 (never needed to replace it, so I’m not positive, speaking from memory), but these things are typically popular enough you get aftermarket replacements specifically built to fit, so I’m not too worried about getting a replacement down the line, even with Nintendo not providing the requried documentation (but seriously, they have to for legal reasons, so they better get to it).

I’m more concerned about getting to the thing in the first place on this one. Plus the battery life is worse, so there’s conceivable a market for larger capacity replacements.

This conversation reminds me I need to swap a suspicious battery on an old Samsung S10 I had in storage and I’m NOT looking forward to dealing with that, either. Maybe I’ll just dunk it in alcohol and hope for the best…
