Yesterday, Apple began notifying first generation iPod nano owners that their batteries may overheat and pose as a safety risk. This issue may only exist on a few models, but Apple requests that users who experience any amount of heat apply for a replacement to prevent any potential injuries caused by the batteries.
Dear iPod nano owner,
Apple has determined that, in very rare cases, the battery in the iPod nano (1st generation) may overheat and pose a safety risk. Affected iPod nanos were sold between September 2005 and December 2006.
This issue has been traced to a single battery supplier that produced batteries with a manufacturing defect. While the possibility of an incident is rare, the likelihood increases as the battery ages.
Apple recommends that you stop using your iPod nano (1st gen) and follow the process noted below to order a replacement unit, free of charge.
Back in 2009, Apple began issuing replacements for affected users in South Korea and, in 2010, they also replaced some units in Japan. Now, Apple has initiated a full-scale worldwide replacement program for all users.
To initiate a replacement, users must fill out a claim form on Apple’s website – providing that they do not have personalization on their iPod, as this will not be accepted. Affected units will be replaced within six weeks and each will include a 90-day warranty just in case anything else goes wrong.
