Windows 7 Battery Bar

Windows 7 Battery Bar is a very simplistic tool whose sole purpose is to build a bar into the Windows 7 taskbar, which shows a meter with the current level of your battery's lifespan. It is very simple to work with it.
This is a portable piece of software, so installing Windows 7 Battery Bar is not necessary. You can just move the program files to any location on the hard disk and run the executable directly.
There is also the alternative of saving the utility to a USB flash disk or similar storage unit, in order to run it on any workstation with minimum effort.
At initialization, Windows 7 Battery Bar creates an icon in the system tray area (where you can bring up and hide the Options panel), aside from showing the battery bar in the taskbar. It looks exactly like the minimized window of any other application, with the meter decreasing as the battery discharges.
From the Options panel you can change the taskbar color (default is green, but other options are red, yellow and auto), as well as write text on it (remaining percent, time, or percent and time, or power status). There are no other settings that can be configured for this tool.
Windows 7 Battery Bar does not put a strain on the computer's overall performance, as it uses a minimum quantity of CPU and RAM, thus it doesn't affect user activity. No error dialogs have been shown in our test, and the utility did not hang or crash. All in all, Windows 7 Battery Bar provides a straightforward, visual solution to keeping track of your notebook's battery status.
