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.
New battery installed. Tested. Case closed :) iPod nano 3G is back for many more years of service, hopefully :) That was definitely a tough repair. These iPod nanos are quite demanding to pry open. But it is done. Onward to saving more devices from ending up at the landfill.
