To check the battery health of your laptop, especially on Windows 10 or 11, you can generate a detailed battery report using built-in Windows tools. Here’s how to do it:

Checking Battery Health via Battery Report in Windows

1. Open Command Prompt or PowerShell as Administrator
   • Click on the Start menu, type cmd or PowerShell.
   • Right-click on the result and select Run as administrator.
   • If prompted by User Account Control, click Yes.
2. Generate the Battery Report

   • In the command window, type the following command and press Enter:

     powercfg /batteryreport /output "C:\battery-report.html"
     

   • This command creates an HTML battery report file saved to your C: drive.

3. View the Battery Report
   • Open File Explorer and navigate to C:\battery-report.html.
   • Double-click the file to open it in your web browser.
4. Interpret the Report
   • The report shows detailed information such as:
     • Battery name and manufacturer
     • Design capacity vs. full charge capacity (important for health)
     • Battery usage history
     • Cycle count (number of full charge/discharge cycles)
   • A healthy battery’s full charge capacity should be close to its design capacity. If the full charge capacity is significantly lower, the battery is aging and may need replacement

Alternative: Check Battery Health in BIOS/UEFI

• Restart your laptop and press the BIOS access key (often F2 or Del) during boot.
• Look for a battery health or battery information section that may provide status and health details

Summary

• Use the powercfg /batteryreport command in an elevated Command Prompt or PowerShell to generate a comprehensive battery health report.
• Review design capacity vs. full charge capacity and cycle count to assess battery condition.
• BIOS/UEFI may also provide battery health info depending on your laptop manufacturer.

This method works across most Windows laptops and provides a reliable way to monitor battery health without third-party software
