"""Displays battery status, remaining percentage and charging information.
|
|
|
|
Parameters:
|
|
* battery-upower.warning : Warning threshold in % of remaining charge (defaults to 20)
|
|
* battery-upower.critical : Critical threshold in % of remaining charge (defaults to 10)
|
|
* battery-upower.showremaining : If set to true (default) shows the remaining time until the batteries are completely discharged
