I got the tools. I got the new batteries. Now wish me luck for replacing the batteries of my 20+ year old iPods. A classic gen 6 and a 3rd gen Nano.
@jwildeboer The Nano, like you have, is the best form factor iPod, in my opinion.
I did a little reading and they’re kind of difficult to upgrade. The standard iPod gen 4 and up are — apparently — easy to upgrade.
