Apple's battery troubles may be continuing as Atlanta-based user and airport employee Danny Williams reported that his second generation iPod nano "burst into chest-high flames" while he was at work.

According to Engadget, the iPod exploded, leaving a burn across a glossy piece of paper Williams had in his pocket at the time and smoking.

The component at fault seems to be the lithium ion battery within the unit and when contacted, Apple offered to replace the unit provided he sent the original back for repair. According the the WSB-TV report that accompanies the Engadget piece, Apple has declined to comment on how common a situation this is.

If you've seen your second generation iPod nano become extremely hot or heard reports of the lithium ion battery exploding, let us know in the comments or forums.
