iPod's are great, but like anything, they need power to run. A long-life lithium-Ion (li-ion) cell keeps the iPod running. After a while, though, they are bound to fail.
When they do, it's no biggie. You can pick up a new replacement iPod battery for next to nothing.
The good news is that replacement iPod batteries have more capacity then the originals, so your iPod will run longer.
They're easy to install, you just need a few simple tools and your head screwed on tight.
