Ahh.. The /proc/acpi/battery info might be the info I need.  It looks
like the "design capacity" and "last full capacity" will give the
information I need.  In my case, design capacity is 4800 mAh and last
full is 768 mAh. This works out about right given that, when new, it
lasted a little under two hours and now it dies in about 10 minutes.

Thanks a bunch...

BTW, someone suggested the battery applet monitor but at least on my
version it only gives the charge state, not the battery condition.
