Windows power meter doesn’t provide so much details about your laptop battery. If you are not charging it, you will see a battery on your traybar. Double clicking it will bring up Power Meter and will display the current power source, total battery power remaining and total time remaining.
To see detailed information about the battery such as name, unique ID, power state, chemistry, and manufacturer of the battery, you can click on the battery in Power Meter.
I found a FREE software that provides much more information about your notebook battery.
Notebook BatteryInfo is able to display the internal values of the Notebook battery. It is easy to find out the battery wear or the maximum usable capacity of the battery. It can even provide a more thorough battery information compared to Windows Power Meter.
I prefer Notebook BatteryInfo over the default Windows Battery Meter because the symbol in the traybar shows only the rough estimate of the remaining battery capacity. If more exact information are needed the mouse must hovered over the battery symbol to show a tooltip with the exact remaining capacity. As for Notebook BatteryInfo, the current battery values will always be displayed on the taskbar, making it much easier for you to know the exact remaining capacity.
