Default Putting As Percentage Of Battery In (GB)?

Hello friends from XDA!
It is a question a little silly ..
but wanted to know how to implement the icon of the battery percentage in Android 2.3?

(No Substitute Framework-res.apk: The Rom That Use (Xelite Gamer 2.0) has one optimized for smooth operation and I Can not Replace.)

(No RomToolBox: Ya Probe and not work)

I hope pudding help me ..
