Guess what?

The battery in my 2004 G5 PPC has never been changed and date and time is correct.
How is this even possible?

You got lucky.

Is your G5 connected to the Internet? If so, that could be the reason because the operating system will obtain the correct date and time settings from online. Most of my iBooks have dead batteries and remain updated via the Net.

If the battery is still functioning after all this time then it's in the miraculous category. The one in my G5 was DOA but yet I have games cartridges from the early 90s whose batteries are still going strong.

Well, they might not have PRAM-batteries at all but a capacitor to do the job. That could be the reason.

The G5's seem to have a battery though, at least mine do.

I stopped using the G5 in 2011 when I bought my 2012 iMac. It was stored in its original box until this year when I pulled it
out to use Photoshop. When I was using it, it was always connected to ethernet.
I’m sure it will now probably die.

Yes, that's definitely correct with the iBook G3's. I don't know if the same applies to their G4 siblings.

Of course they do. The same type that's used throughout most of the Apple PPC and Intel desktop line. I needed so many that I bought a large pack and replaced score of dead ones in my iMac G3 through to my Mac Pro 1,1.

How about now?

Have faith!

Ps. I do have an iBook G4 14".

Yes, I have replaced them to most of the machines I have ever opened, including almost all of my G5s. Today I ordered more of the BR variety to use in my new Mac Pro and some future machines. Basic stuff in this hobby.

Ah, gotcha! Thanks for the clarifier.

I desoldered the West German battery in my Macintosh SE and installed a modern holder unit so that it could use removable batteries, which were as you can guess, the 1/2 AA 3.6v type from my stash.

Hobby? This is a religion.
