Always displays battery icon in windows 7 system tray

How to move an icon (in my case I wanted to move battery icon) from that “hidden” system tray space so it will always be visible in system tray?

Simple, just click on the up arrow to display that “hidden” system tray area, grab the icon (hold the left mouse button) you would like to move and just move it to¬† the always-visible system tray area.
