The http://www.everymac.com site says the same thing, 3.6 v Lithium...that should be the short, cylindrical battery...you should find it at most electronics supply stores.

You want the half-AA 3.6 volt Lithium battery. Most often, the two brands are Tadiran or Saft. Two most-common Tadiran numbers are TL-2150/S and TL-5902/S.

Thanks for the details. It should be enough to find the right widget, even here in the battery-unfriendly Belgium.
Admittedly, I could have opened up my Mac and looked at the old dead battery, but the fewer times I have to crack it open, the better. I have a tendency to upgrade things pointlessly but at great expense just because I have the silly thing open...

As a postscript to my above post, in case the links go dead, here is a picture of the two most common 3.6 volt Lithium PRAM batteries which go in a whole bunch of Mac models from my first Mac IIci up to the early 2005 G5 towers (with a normal AA battery for reference):
The Tadiran battery in the picture was just removed from a Power Mac 7200/120 that has been out of service for a while (probably was the second one into the machine, given the 1999 build year), and the Saft was pulled from my G5 a few weeks ago after about three years service. That was just periodic maintenance, as the battery was still fine, just not fresh.TiBook G4 1GHz/ G5 2 GHz DP GF Ultra 6800, Mac OS X (10.4.11)

Great work as usual OCG!
I've been doing some organizing this summer and have come across some pretty interesting stuff. One thing I haven't kept, apparently, is one of those odd PRAM batteries that were in some of the Performas and maybe some of the SE boxes. You know, the square goober with the Velcro™ mounting scheme? I still have the long (12 inch) Torx™ screwdriver needed to get into some of those things.

Yeah, the 4.5 volt ones...
Then the earlier 4.5v for Macintosh 128K, Macintosh 512K, 512KE, and Macintosh Plus...
That 4.5 volt cell dates back to when I could only afford a typewriter, TI calculator, and had to use stamps to send mail, and the only computing I was doing was through a VT-100 terminal (at least a step up from a Hollerith punch). I note for the record that the lower picture depicts the last PRAM battery that was fundamentally easy to replace, thank you very much. At least by the time we got to the Gee Macs you didn't have to eviscerate the machine to add RAM or change batteries.TiBook G4 1GHz/ G5 2 GHz DP GF Ultra 6800, Mac OS X (10.4.11)
