Taskbar status application BatteryBar adds a battery life meter to the Windows taskbar with detailed battery life information and eye candy in a mouseover dialog.

Once installed, activating BatteryBar is as simple as right-clicking on the taskbar and choosing Toolbars -> BatteryBar from the menu. The meter button changes from blue to green when you are on battery power, and clicking on the meter button switches the display between actual time remaining or a percentage view.

BatteryBar is a free download for Windows only. If you would rather put your battery meter on your desktop, check out Power Meter Plus.

Additional features in the Pro version

Low Battery Warning

BatteryBar monitors your battery life and when your battery power gets low, BatteryBar will notify you with a popup window and a sound. A second notification window appears when your battery reaches critical level.
