A lot of people still think that the only way to check the MWh (megawatt hours) of a battery is to remove it from the device and inspect the information stamped on the battery. Although this is one way to find out the information, it isn’t the only one. For instance, you can also search your devices make and model online to find out this information, without removing the battery.
If the device you are using is running Windows 10, you can use Command Prompt to create a battery report that will show you current battery capacity, original design capacity, chemistry, serial number, and the manufacturer. The best part about this is that you don’t have to physically remove the battery and can check your batteries overall degradation and a huge range of other statistics.

To start the process of finding out your remaining battery capacity on Windows 10, you’ll need to open the Command Prompt tool as Admin. To do this, search CMD from the start menu, then right-click on it and select Run as Administrator. Once you have Command Prompt open, copy and paste the following command into the window and press Enter.
powercfg /batteryreport
Once done, navigate to the following location using File Explorer: C:\Windows\System32 and double click on the battery-report.html file. This file will contain all the information related to your system battery.
Below is a brief example from my laptop. (The entire report is quite long)
NAME: DELL 098N05B3
MANUFACTURER: Samsung SDI
SERIAL NUMBER: 984
CHEMISTRY: LION
DESIGN CAPACITY: 66,906 mWh
FULL CHARGE CAPACITY: 55,112 mWh
CYCLE COUNT: -
The report also shows you battery usage drains over the last 3 days, historical data (which can go back years), and of course one of the most important things, battery capacity history. There are also remaining battery life estimates available, however, these should be taken with a grain of salt. It should also be noted that these results will only show you historical data from when your operating system was last installed. If you have a clean installation of Windows, a lot of this historical data will be blank or short dated.
