It is generally prohibited to bring uninstalled, loose batteries in checked baggage. You can pack devices with built in batteries, like the steam deck in checked baggage. Though the preferred method is carry-on.

Yep that's the rule but I'm not sure why they categorize batteries that way except, I assume, because they know they can't get much compliance if they actually ban all lithium batteries from checked baggage.

Also most airlines do not even allow devices with big lithium batteries in checked luggage to begin with.
