Apple store battery replace

Apple does WUR replacements on these given the battery is soldered.

The good news is that Apple does not consider your iPod either vintage or obsolete, so they will indeed replace the battery for you.

You can get an estimate for the cost yourself under their support pages here.

This is for the US; if you're in another country your cost may vary, but otherwise you're looking at about $80 for the replacement. A local repair shop can undoubtedly do it cheaper if you're open to that.

iFixit doesn't have a guide for do-it-yourself battery replacement; in my experience they tend not to create guides for parts that are soldered in, as the battery for your iPod is. The question of why there isn't a battery guide has come up before; here's a question that addresses that.

You can, however, buy a battery from iFixit should you choose to attempt this on your own.

The only criticism I have of this guide is that they don't take the extra step of replacing the battery adhesive. Although the old adhesives strips might be fine, if it was me I'd scrape them off and use new ones. Other than that, it gives you all the information you need.
