The default battery indicator on laptops powered by Windows XP, Vista and 7 shows only the most basic information—% of battery juice available, estimated time left before the battery dies off, and charging or plugged in. You are simply out of luck if you want to know more about your laptop’s battery using it.
Whether you are a road warrior who cares much of your battery’s health or is just simply curious about it, check out BatteryBar. It sits beautifully on the taskbar indicating the percentage of battery juice left or time left depending on preference. Hovering it will reveal:
- Percent of battery juice left
- Capacity of battery – e.g 12,443 mWh of 17,294 mWh
- Charged rate – e.g 13,642mW
- Battery life left in time – e.g 0:34
- Full battery lifetime in time – e.g 1:00
- A/C – connected or disconnected
- Battery wear – e.g 700% of 57,720 mWh
