Determine battery health with Windows 7

Windows 7 includes an utility to offer details concerning a battery with a laptop.  Verify that your battery is connected.  Open a command prompt with administrative authority and enter:

powercfg –energy –output filepath\report.html

powercfg

Within the report.html file, a section should be present that contains details about the battery.

powercfg_2

The laptop above was new, so the capacity and last full charge values are the same.
