The telltale signs of old age are a loss of memory and hearing, and a tendency to sing battle songs to surly waitresses. Keep your memory fresh today with our PowerBook G4 PRAM battery.

The PRAM or backup battery is responsible for holding the date and other settings when your computer is shut down. If your computer's date resets to 1904, you need a new PRAM battery.

This does not come with the rest of the PRAM assembly which the battery is attached to. It will require soldering but it's a very easy task.

Check out this guide to show you how to change your PRAM battery.
