xbattbar | Display battery status in X11 | Mehr ...
Xbattbar displays the current (laptop) battery status in the X window environment. Battery status is obtained through the APM interface. . The battery indicator of this program is very simple: a simple bar at the top/bottom of your display. With its color, it indicates the AC-line status (plugged in or off-line), and battery charging/remaining level. Also, if the mouse cursor enters the indicator window, a popup diagnosis window comes up in the center of your display showing the current AC line status and battery level. . If you use ACPI take a look at xbattbar-acpi.
