A law firm in California is investigating a potential class action against Apple Computer on behalf of iPod owners whose batteries have died or lost their ability to hold their charge.

Girard Gibbs & De Bartolomeo LLP is requesting that iPod owners who have experienced problems fill in a form on their Web site.

Apple Europe PR manager Alan Hely told Macworld that Apple would soon be offering European iPod owners an iPod AppleCare package, which will offer a replacement battery if required. This package has until now only been available in the US.
