I've never let my battery get down to 3% without needing a charge.
I'll try it tonight and see if I get a beep.

To the OP, here's a script to spawn xmessage when your battery is too low.

#!/bin/sh
if test $(cat /proc/acpi/battery/BAT0/state|grep remaining|awk '{print
$3}') -le 500; then
        xmessage -center -buttons "nothing:0,hibernate:1" "Your battery is
low, what do you want to do?"
        DO=$?

        if test $DO -eq 1; then
                echo hibernating
        fi
fi
