In response to the controversy caused by iPod users finding out about the limited overall lifespan of the internal
battery inside earlier models of the iPod, Apple introduced a battery replacement program, where you can send
your iPod to an Apple Service Centre, and have the dead battery professionally replaced by an Apple technician.
Apple obviously charge a fee for this service. Although, having just looked on
Apple's website, this seems to
have since been replaced by the
Apple Care Protection Plan for iPod, which covers not just the iPod and
it's battery, but also other accesories sold with the iPod, such as the earphones, and the dock connector.
Given the fact that the iPod is rather an expensive item, I'd recommend putting some sort of insurance on it!
Alternatively, there are ways of replacing a dead iPod battery yourself, and you should be able to find guides
on the internet that show you how to do this. Look up "Replacing an iPod battery" or other similar search
terms on Google. Bear in mind though, if you decide to perform battery surgery on the the iPod yourself,
you'll invalidate the warranty, and you could permantently knacker the thing. Meaning another £200+
would have to be spent on buying yourself a brand new iPod, to replace the one you fecked up!
