BatteryBar is a simple, straight-forward, battery meter that monitors the status of your battery and displays your battery's status in the taskbar.
BatteryBar constantly monitors the status of your battery as you use your laptop. As it monitors your battery, it keeps historical data on your battery and provide you with a very accurate estimate of how much time is remaining on your battery.
After installing BatteryBar, you can upgrade at anytime to BatteryBar Pro. After your purchase you will be given a license key that will unlock all the features of the Pro version without installing any new software.
When you're running on battery, BatteryBar shows the percentage bar in green, yellow, or red, depending on how much battery power is remaining. The bar displays the time left on your battery in Hours:Minutes
When charging, the percentage bar is shown in blue to indicate charging, and the estimated time to full charge is shown. The bar turns black and shows "On A/C" when fully charged.
