To graph the level of battery charge, the program uses a system of previsualization of bars and progress that is included in Windows 7.
Among the program options you can find various actions to reduce battery consumption automatically when the computer is unplugged.
You can also change the look of the bar and set levels that you think are low and still let your computer run.
SuperbarMonitor.Battery is a great option for those who like to always be able to see the status of the battery's charge.
Requires Windows 7
