There's an article at

on connecting up a 9V 1A battery. Note that the Portable uses Pb
batteries as opposed to Li-on.

Careful though - a faulty battery was the cause of the meltdown
(literally) I experienced.

As far as wall-wart power supplies, I'm fairly certain there are still
refurb outfits that sell these (and other Mac portable parts). You
might start your search at the Low End Mac site (couple of battery pages
here as well).
