Apple - 3.6v 1/2AA off-brand (I don;t have an original one around here to check, even). Lithium. Expensive, hard to find. Or, even worse, a few REALLY choice models had a really odd, box-shaped thing. Rayovac 1.5v Alkaline, I think.
Everyone else in the known universe - 3v Sony CR2032. Lithium. You can get them at f'ing Walmart with the watch batteries.
Of course, it doesn't matter that the CR2032's are easy to find - they last FOREVER. And when I say forever, I mean "I've never seen a dead one." I have two 286's here with 2032's in them. They still work.
But Apples.... They die every 2-3 years it seems. I know they still used them in the G3's and G4's - because I've replaced them; don't know about the G5's. And I pray for those of you with their laptops, because I suspect they have this same ticking timebomb of a battery in them (though, I'm not sure if one would even FIT in the physical height those systems afford, so it's entirely possible that they used a sane battery)
