Both types are currently available
Handhelds are prone to a certain amount of wear and tear over time: and I should talk, as someone who owns a collection of them! Some of mine are completely beaten up from constant use (and dropping them as a kid), and others are in pristine condition: compliments of my collector habits throughout my lifetime. But whatever the case might be,if you need a3DS(or 2DS, or New 3DS, and so on) battery pack, Nintendo has official ones in stock now: no need to worry about a secondhand clunker.

If you’re the type of person whoconstantlyplays 3DS and is enjoying all of those now-dead games, you might want to grab an extra or two for your model of choice. These things are relatively cheap by Nintendo standards and aren’t always in stock. Remember that Nintendo changed their policy to allow free shipping for orders over $50.
Nintendo does have a helpful tip for those of you who are having 3DS issues though:
“If your system is not charging or holding a charge properly, we recommend checking our troubleshooting before deciding on a replacement. You’ll need a small phillips tip screwdriver (not included) to open the battery compartment before you can replace the battery.”
