This issue is not directly related to Ubuntu but i will explain shortly.
Ubuntu monitors the data transmitted by so called smart batteries.
Over time batteries are loosing capacity, a little bit with any loading cycle.
The battery will load to 100% of the actual capacity. But if it falls below 50% Ubuntu will give a warning.

To deactivate the warning, press Alt+F2, run "gconf-editor" and in the opening program switch of the key /apps/gnome-power-manager/notify/low_capacity.
