Toggle iPod Battery Status is a tool to switch between the two options (including one hidden option) for iPod Battery Status display. Your two options are the default "Icon" view, showing a picture of the battery with the dark part filled to indicate how much current you have left. The other view is a "Numeric" view. It shows a number between 0 and ~500 to indicate your voltage. This software automatically detects which setting you are currently using and switches to the alternate method.
