Screenshot? There should be only one Default value, interesting there are two.

This in itself does not alter the behavior...it allows you to go into your notification settings in the system (same place to change the ringer), and modify settings there.

I turn it off altogether, because I don't need my Omnia whining at me at 40% battery life. It still notifies you when you hit 20% or so.
