How do you replace the battery in the iPod, iPod mini, iPod nano, or iPod touch?

If the iPod is out of warranty, Apple will replace the battery in your iPod or iPod shuffle for US$59 and the iPod touch for US$79. A variety of third-party services also are available, including site sponsor Other World Computing, which offers a battery replacement service for US$39 including two way shipping.

It is not particularly easy, and potentially not cost-effective, to replace the battery in the iPod nano, iPod shuffle, or iPod touch models, as these batteries have leads soldered to the logic board. Replacing the battery requires one to either replace the logic board as well as the battery or carefully remove and resolder the leads. Self-installation is only suited for the technically adept. The battery in the full-sized iPod and iPod mini models, however, can be replaced by a patient and careful individual.

The always excellent iFixIt has self-installation manuals for each iPod with battery replacement instructions when applicable.

How do you replace the hard drive in the iPod or iPod mini?

If the iPod is out of warranty, Apple will replace the hard drive in the iPod or iPod mini models for about the cost of a new iPod, and consequently, such a replacement tends to not be cost-effective.

Alternately, if you have the technical skill, you could purchase a replacement hard drive and install it yourself. Instructions are available from the authoritative MacUser UK, and the less authoritative, but far more in-depth, Josh Highland's "Blog/Journal/Whatever", as well as iFixIt.

How do you replace the iPod display?

Like the hard drive, if the iPod is out of warranty, Apple will replace the display for an amount that is generally not cost-effective, but third-parties are available to replace the screen as well.

Even if your iPod is under warranty, Apple states that "if your iPod's LCD display is cracked due to accidental damage, do not send your iPod in for service. Coverage for this type of damage is excluded under Apple's Limited Warranty for iPod and AppleCare Protection Plan for iPod, and service is not available under the terms of Apple's Repair Terms and Conditions." Fortunately, the company is believed to continue to replace the iPod nano display if a factory defect causes it to become damaged during routine use.
