2 years ago I had an intermittent failure of clock/date and control settings,
and traced it to a broken soldering on the analog board right were the
battery case is connected to the circuitry.  rather tricky to detect, too,
because it was making contact *SOMETIMES* and had to be discovered *VISUALLY*
rather than with the voltmeter.

I also learnt at that time, that while the Mac is under net-power the PRAM
settings are maintained by the line-power and that it takes about 5 to 10
minutes before the PRAM-settings fully depend on the battery voltage.
So quickly turning the Mac ON and OFF didn't really test anything.

You mention that "three my Mac ate in the last 24 hours" (batteries) - sounds
like a short to me ....  hope you had AppleCare; I hate it when *ANYONE* has
to pay $$$$ just for detecting a little lose wire somewhere ...

On the other hand, someone with a "Cray X/MP" probably has a PLATINUM card
and couldn't care less ...(-:
