One of the greatest features of a laptop is its battery life; as it is created for mobility. If you ever wanted to know how to check your laptop’s battery health or maybe you want to buy a used laptop but you’re not sure about the battery. In this post, I’ll show you how to simply do it.
Now here is the thing, most laptop batteries will start to fail after 1 or 2 years, this varies depending on the usage of course, but the average laptop battery is good within the first 6 to 8 months of everyday recharges, based on experience. To expand your battery life don’t leave your laptop battery on charge permanently like if you’re using a desktop PC. After your laptop is fully charged, unplug it from the charger or if you prefer you can remove the battery and leave your machine plugged into power until you are ready to move then you can fix the battery back again.
How to Check Laptop Battery Health
First, you’ll write a command using the Command Prompt (CMD), so let’s run CMD as Administrator.
Type the following command cd %userprofile%/Desktop and press Enter
Next type this command powercfg -energy and press Enter
Allow the command to run, when it’s done it will create an HTML document on your Desktop called energy-report.html because we directed the command prompt to the Desktop.
When you open the HTML file you will see some other diagnose and analysis made by the command. Scroll down up to the Battery Information section
As you can see the Design Capacity of my laptop’s battery is 62160 and the Last Full Charge is 26090 which is way below the design capacity. Two years ago this battery runs for more than 4hrs, but now just for about an hour. So that means the battery is almost gone and I need a replacement. If you’re buying a used laptop and you’re very much concern about battery life consider at least 60% to 50% of the actual design capacity.
Thanks for reading and hope this tip helps. See you on the next post.
