PowerBook G4 Aluminum 15" 1.5-1.67 GHz PRAM Battery Replacement

crwdns2934249:0crwdne2934249:0:

Hi:

My pram battery is clearly dead. Time, date, and wi-fi settings are not saved once the Powerbook is unplugged.

I appreciate the iFixit guide for removing the pram battery! That part I can manage relatively easily.

My issue is that only used battery module replacements are available from eBay. Their remaining battery life is dubious, to say the least.

I would like to desolder and solder a brand-new pram battery onto the small printed-circuit module that holds it.

Does anyone have any experience doing this? Is it safely doable? Suggestions welcome.

Thanks in advance for any help you may have to offer.
