Kensington has announced a pair of extended life batteries for the iPod and iPhone. Both work with any iPod with a dock connector and the iPhone. The larger device costs US$69.99 and adds up to 6 hours of talk time and 100 hours of music playback. The mini device adds 3 hours of talk time and 30 hours of audio.
