Apple: Original iPod Nanos Can Heat Up

Apple says that in rare cases the battery of the original iPod nano may overheat and pose a safety risk.

Apple has added another issue to be concerned with to the battery woes in some of its most popular hand-held devices -- overheating.

Apple issued a statement saying that in rare cases the battery of the original iPod nano -- sold between September 2005 and December 2006 -- may overheat and pose a safety risk. And apparently that risk increases as the battery ages.

Apple says the problem stems from a manufacturing defect in batteries made by a single supplier.

Before sending you a new one, Apple will check your nano's serial number to verify it may have the battery problem. If so, and if you want to participate, you need to send it to Apple and wait six weeks to get a new one.

While it's hard to imagine the small music player heating to a dangerous point, the fact remains that some nano owners will be able to trade in their old units for new ones -- that is, if particular models happen to be included in the replacement program. 9to5 Mac is reporting that not all first generation nanos qualify.

Apple isn't saying which model they are issuing as a replacement but if it's sending out 7th generation models it would be a good deal for conscientious iPod owners who have managed to keep track of their aging devices.

If you have an engraved unit and want to participate in the replacement program, you'll need to say goodbye to whatever words are etched on your unit -- Apple is only sending out non-personalized replacements. You'll also want to use iTunes to back up any data on your old iPod nano before sending it in.

Qualifying models have a black or white plastic front and a silver metal back -- later iPod nano models have a metal front and back.

The iPod nano development comes on the heels of weeks of battery woes involving the iPhone 4S.
