Windows 7 Battery Bar is a free tiny portable tool that monitors the status of your battery and displays it in the taskbar.
To customize the settings click on the the Battery icon in the system tray. You can change the taskbar color to Red, Green, Yellow & Auto. If you change the color to Auto then it will change the color according to the remaining battery percentage:
100% - 50% = Green 49% - 11% = Yellow 10% - 0% = Red
