Stories of iPod batteries catching on fire are sadly nothing new—we’ve been hearing about them for over a year. But on Friday, Apple published a knowledge base document publicly acknowledging the problem—and that may be a first.
In these rare cases, the battery may overheat, causing the iPod’s case to become distorted and the iPod to stop functioning. If you notice those symptoms or other signs of the battery overheating, such as discoloration, Apple suggests you stop using the iPod immediately and contact AppleCare. In addition, if you are concerned about the battery in your iPod nano, you can also contact AppleCare for a battery replacement.
