Sorry, forgot to mention this. I'm running debian linux.
You should be able to read/poll the various files in
/proc/acpi/battery/BAT*/*
for whatever battery information you need. Each BAT* directory
contains information about one of the batteries in the system
(it's possible, albeit rare, to have more than one). So you
might have some script that runs every $INTERVAL that looks
something like
from glob import glob
for fname in glob('/proc/acpi/battery/BAT*/*'):
f = file(fname)
for line in f:
do_something(line)
f.close()
On my Debian laptop (Gateway Solo 1200, OEM battery circa 2001),
the contents look something like
