Statistical Time Prediction, this is the most important feature of BatteryBar.

BatteryBar keeps historial data on your batteries as you use your laptop. That information is used to calculate a very accurate estimate of the time remaining on your laptop.

Windows reports a time remaining that's very simple and fluctuates wildly from moment to moment.

Discharging
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

Charging
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.

Other Features
Vista style - The toolbar is using the same look and feel as the Vista taskbar buttons
Statistical time prediction - BatteryBar monitors your battery and keeps a history of how long it takes for your battery to charge and discharges. That information is used to more accurately predict the life of your battery
Translations - BatteryBar fully or partially supports 13 languages. Anyone may volunteer to translate BatteryBar to additional languages
Detailed Battery Info - BatteryBar is now capable of collecting detailed information about your battery, including max capacity (mW), current capacity (mW), charge rate (mW), discharge rate (mW), and more.
Automatic Update - BatteryBar will check for new versions at startup and automatically download the new version
