Ok i was playing around and moving my icons in different order when i accidentally dragged the battery icon off and "poof" (literally, there was a puff of smoke and everything lol) its gone! how do i get it back?
Take a look in System Preferences under the Energy Saver pane at the bottom there's a 'Show battery status in the menu bar' option that if you select it will... well, I'm sure you can work the rest out yourself.
