Just learned draining a L-ion battery completely will permanently damage the battery's capacity. I won't be purchasing a new battery until I can be certain that gnome-power-manager will provide the proper warnings/actions to prevent damage to a new battery. I have looked at the gnome-power-manager source code, but I'm currently not confident that it is getting the proper information from the /proc/acpi/battery/BAT*/info file to properly provide a warning or take action when the battery is at a critical charge state. Here is my battery's info.

present: yes
design capacity: 5200 mAh
last full capacity: 354 mAh
battery technology: rechargeable
design voltage: 12597 mV
design capacity warning: 300 mAh
design capacity low: 200 mAh
capacity granularity 1: 32 mAh
capacity granularity 2: 32 mAh
model number: NS2P3SZNJ5WR
serial number: 17249
battery type: LION
OEM info: SANYO

I'm currently working on a perl script to see if I can get the functionality I need in order to insure my next battery stays fully functional. Here's a paste of the script if you are interested in utilizing it/updating it for your needs. http://paste.ubuntu.com/340361/
