4. Tips for Maintaining Battery Health
Proper care and maintenance can significantly extend the lifespan of your laptop battery. Here are some practical tips to keep your battery in top condition:
1. Avoid Overcharging
Leaving your laptop plugged in all the time can reduce battery life. Unplug it once it reaches 100% to prevent overcharging.
2. Keep Your Laptop Cool
Heat is one of the biggest enemies of battery health. Ensure proper ventilation and avoid using your laptop on soft surfaces like beds or couches that can block airflow.
3. Use Battery Saver Mode
Enable Battery Saver Mode on Windows to reduce power consumption when your battery is low. This can help extend battery life during critical times.
4. Calibrate Your Battery
Calibrating your battery every few months helps maintain accurate battery level readings. To do this:
- Fully charge your laptop to 100%.
- Let it drain completely until it shuts down.
- Charge it back to 100% without interruption.
5. Store Your Battery Properly
If you’re not using your laptop for an extended period, store it with a 50% charge in a cool, dry place. Avoid storing it at full or empty charge.
6. Update Your Software
Keep your operating system and drivers up to date. Manufacturers often release updates that optimize battery performance.
7. Reduce Background Processes
Close unnecessary applications and disable startup programs to reduce battery drain. Use the Task Manager to monitor and manage background processes.

1. Poor Battery Performance
If your laptop battery no longer holds a charge or requires frequent replacements, it might be more cost-effective to sell your laptop and invest in a newer model with better battery life.
2. Outdated Hardware
Older laptops with outdated processors, limited RAM, or insufficient storage can struggle to run modern applications efficiently. Upgrading to a newer device can significantly improve your productivity and user experience.
3. Frequent Repairs
If your laptop requires constant repairs, such as fixing the keyboard, screen, or internal components, it may be more economical to sell it and purchase a new one.

How to Test Your Laptop Battery on Windows
In this video, we demonstrate how to test the capacity of your Windows laptop battery. This process works for any version of Windows, from 7 to 11, except for devices running in Windows S Mode. However, please note that this test isn’t fail-proof, and there are scenarios where it may produce inaccurate results. We’ll also cover a specific issue with HP laptops later in the video.
Step-by-Step Instructions
- Open an Elevated Command Prompt: Launch PowerShell, Terminal, or Command Prompt with admin privileges.
- Generate the Battery Report: Type
powercfg /batteryreportand press Enter. This creates a battery report and saves it to a default location. - Save the Report to a Convenient Location: To make it easier to access, modify the command to
powercfg /batteryreport /output c:\BR.html. This saves the report asBR.htmlin the root of the C drive. - Open the Report: Type
C:\BR.htmlin the Command Prompt or Run dialog to open the report in your default browser.
Understanding the Battery Report
The report includes key details such as:
- Design Capacity: The battery’s original capacity as specified by the manufacturer.
- Full Charge Capacity: The current maximum capacity of the battery.
- Cycle Count: The number of charge cycles the battery has undergone.
To calculate your battery’s health, divide the Full Charge Capacity by the Design Capacity. For example, a battery with 49Wh (full charge) and 51Wh (design) has 96% health.
Common Issues and Exceptions
While this method is generally reliable, there are exceptions. For instance, some HP laptops may display incorrect full charge capacity values. If your report shows identical design and full charge capacities, it could be inaccurate. To verify, check the battery’s physical specifications or use HP’s Part Surfer tool.
Using HP Part Surfer
For HP laptops, follow these steps to confirm battery specifications:
- Find your laptop’s Product ID using the
msinfo32command in the Run dialog. - Enter the Product ID on the HP Part Surfer website.
- Locate the battery details to compare with your battery report.
Conclusion
This method provides a quick and mostly reliable way to test your laptop battery’s health. If your battery is underperforming, consider replacing it or selling your laptop to upgrade to a newer model.
