Is it possible to have more than two batteries in a laptop?

Is it possible to have more than two batteries in a laptop?

[Hanno Böck]

I'm currently working on a patch for the gnome battery-applet (battstat-applet) to work with two batteries.
Now I have a version working with two batteries, but it would not work if there are more than two batteries.
So I wanted to know if there are laptops which can have more than two batteries at the same time?
If not, my patch is fine. If yes, I would have to enhance it.

(If you are interested in the patch: it's against gnome-applets-2.0.3 and you can grab it at:
www.gentoo.org/~hanno/battstat_two_batteries.diff
)

as any other people patching batstat-applet, you're hardcoding into it
the names of *your* apci devices. my ac/dc is names AC (and not ACDC
like yours) and the battery is BAT0. the _only_ way to have a battstat
working with any hardware is to scan the /proc directories and use the
names found here.

You should look at ACPI spec. I hope they were not so stupid to limit themselves
to 2...

Yes, at least the Compaq Armada Series is able to handle up to three batteries.
