I used either the portable, or more likely the external charger, to do
this. I had 3 batteries at the time.

12V would not be good . . .

That won't even work with the standard charger--it didn't have enough
juice to spin up the HD from rest without battery assistance.

No. Too much voltage, and this applies, but current is is not an
issue--if the circuitry would draw more than 1.5A given the chance,
the voltage would be dropping on the 1.5A supply.
It's really only the issue of the minimal amount of circuitry between
the power supply and the battery; not the computer itself. And even
that little bit is fuse-protected (been there; changed that. Symptoms
of blown fuse are the same as on the 1xx series [and on a 2008
macbook; i just haven't found that fuse or its value yet . . .{not
that I have one waiting to fix the fuse on . . .])

But the board past the battery will never draw that, save for the
amount it's designed to draw during powerup.
