• Make note of where the positive (+) side connects so to eliminate confusion when you try to install the new battery.
• There are only two locations where you will need to solder.

Step 2

• With a soldering iron, place the tip on the first joint and hold it there until the solder liquefies allowing you to pull the battery’s terminal away.
• The soldering iron is extremely hot so be sure to keep your fingers away from the metal. You also want to make sure you do not touch anything other than the solder on the assembly board.
• Do the same for the second, soldered joint.

Where is the PRAM battery located on this model, on the logicboard?

I can’t seem to find these batteries anywhere. Can someone post a source? Thanks!

I posted details, and a source for the battery, over on the Powerbook G4 15” PRAM battery replacement page: PowerBook G4 Aluminum 15" 1-1.5 GHz PRAM Battery Replacement

It should be the same thing here.

Be careful! Not all Powerbooks have this one battery. My 17” Powerbook G4 Aluminium has two CGL 2430. The board looks much different to the one in the above photos. The batteries are smaller (smaller diameter), and the module is longer and narrower. I just opened my Powerbook G4 to replace the battery, just to realise that I bought the wrong battery!!
