So I'm starting to use my PowerBook G4 as my go to instead of my MacBook (White early 2009) but the only factor really keeping me from using it on a day to day is the PRAM battery being dead. It makes the entire thing an inconvenience to use. I looked on ebay for a legit replacement but they all look old and used. Now in the little pouch with the battery in it, It looks like its a standard CMOS battery. Can I just (carefully) remove it doing my best to leave the contact points intact and then shoving a new battery in there? Some tape to put it back together, maybe some copper wire if I mess up the contacts. I just want it to work, don't care if it doesn't look good.
