Power off your iPod, and put it on hold to keep it from turning on during repair.
Force your fingernail between the plastic and metal to create a gap in the casing seam. Pry the two sides of the casing (plastic and metal) slightly apart with the pry tool, then slide the tool all the way around the device to release the tabs.
Remove the hard drive by lifting the drive, then pulling out the copper connector.
Pull out the battery and snap out the connector with your fingernails. Plug in the new battery, lay it in place and accommodate the wires on top of it.
The first piece of your iPod to give out will probably be the battery. Fortunately, replacing your iPod's battery with an aftermarket battery available from online retailers is cheap and relatively simple.
