BatteryMate XP 1.0
Replace your Windows battery meter with BatteryMate XP.
The program continuously monitors your battery to provide accurate time-remaining predictions. It graphs battery performance and estimates current operating efficiency. It includes a 40-state taskbar battery icon, large graphical pop-up status (when hovering over icon) and fade-in 5 and 10 minute warnings. And it offers full support for multiple and dual battery users.
