This battery issue is specific to the iPod nano (1st gen) and does not affect any other iPod.
Apple will check your iPod nano serial number and verify if it is eligible for this program. Then you can send them your current iPod nano (1st gen), and get an new replacement unit approximately 6 weeks later. If your country is not listed, online service is not available for your location.
How to identify a iPod nano (1st gen)? It has a black or white plastic front and a silver metal back – later iPod nano models have a metal front and back.
