iPod has an internal, non-user-replaceable battery. For best results, the first time you use iPod, let it charge for about four hours or until the battery icon in the top-right corner of the iPod display shows that the battery is fully charged. If iPod isn’t used for a while, the battery might need to be charged. The iPod battery is 80-percent charged in about two hours and fully charged in about four hours. If you charge iPod while downloading files, playing music, viewing videos, or viewing a slideshow, it might take longer. With your iPod, you can take your music and audio collection with you wherever you go. Read this section to learn about downloading music and listening to iPod.
