The Creative Zen MP3 personal audio player runs on a rechargeable, replaceable Lithium-ion battery pack. The battery can weaken over time and lose its ability to hold a charge, eventually requiring a replacement. Unlike some MP3 players, the Creative Zen is designed for quick battery change-out with a slide-ff back panel, so the owner will be listening to tunes within a few minutes of removing the old battery and popping in a replacement.
