PowerBook G4 replacing PRAM battery

History

I have a PowerBook G4 1.25 GHz ("FW 800").

I have the symptoms of a failed/failing PRAM battery- loses date/time.

I have removed the PRAM board and notice:

1. The size of the Panasonic CR-2032 is larger than replacements I have bought

2. The battery measures almost 3.9 V with a volt meter.

So is it probably the entire board that has gone bad rather than just the battery?

And if I wanted to replace just the battery where would I find one that would fit?

Thanks

Thanks Mayer, I know all that. First of all I was wrong about the difference in sizes between the one in there and the replacement. I was confusing a 3032 with a 2032. But the fact that it reads 3.9 volts with a meter is somewhat puzzling.
