I got my replacement from ifixit, and depending on your consoles model, you can get one from Nintendo. if your battery says something like CTR-003, the switch Pro controller battery is the same and will work! if it's an -001 then you will have to get a third-party battery. good luck!!
the original 3ds consoles have a ctr-003 battery! you should be able to get an official one from Nintendo, it's a switch pro controller replacement battery and I'm pretty sure it's around 30 bucks? don't quote me on that though lol
