Chosen Solution
I have a 120gb iPod classic and I’ve known the battery hasn’t been great for a long time now. About 8 months ago, I was only able to listen to it connected to power and once disconnected it would die in 5-10 minutes. Now I can’t even get the iPod to power on to the menu regardless of a power source. It’s rebooting extremely quickly (the Apple screen is flashing every 2 seconds nearly) and from all the troubleshooting pages I’ve found on the internet, I haven’t had any luck thus far. When I hold the Menu+Center buttons, the iPod will momentarily respond by keeping the Apple screen displayed until it begins restarting once more in a few seconds as I continue to hold the Menu+Center buttons. I have also tried to put it in disk mode by doing the above, and as the screen begins to reboot, pressing the Back+Forward buttons down simultaneously. This has yet to make the iPod respond any differently as it continues its rapid reboot cycle. Any help here is greatly appreciated. I have a lot of old music I won’t be able to find anywhere on this thing. Thanks!
Unfortunately I think replacing the battery is the only option in your case. It is a relatively difficult process to replace it, but it is possible. Here’s a link to the one on the ifixit store: iPod Classic (Thin) Battery
Had this same. You need to replace the battery.
