Many laptop users don’t realize that Windows provides a simple way to check detailed battery information. You can view how much battery life is remaining, the number of times your battery has been charged (cycle count), the manufacturer, the serial number, and even the date the battery started being used.
This information is incredibly useful—whether you’re buying a new or second-hand laptop, troubleshooting battery issues, or trying to extend your battery’s lifespan. Knowing your battery health helps you decide when it’s time for a replacement and ensures your laptop performs reliably.
Checking your battery health can also save you from unnecessary expenses or fraud. For example, imagine buying a new laptop that accidentally gets damaged. You take it to a repair shop, and the technician secretly replaces your original battery with an old one. You pay for the repair but soon notice poor battery performance. If you had checked the battery report, you could have detected the swap immediately and saved money.
Similarly, when buying a second-hand laptop, checking the battery report helps verify the age and remaining capacity of the battery, ensuring you don’t get cheated.
The easiest way to check your laptop battery is by using software like PC Health Checker. After downloading and installing it, you can open the software to see the remaining battery capacity, RAM details, SSD or HDD size, and other system information. This method gives you a quick and convenient overview of your laptop’s battery health.

Press Start and search for cmd.
- Open Command Prompt.
- Type the command:

- Copy the file location and open it in any browser to see the full battery report.
This report includes:

Over time, as your battery ages, the full charge capacity decreases compared to the design capacity.
You can also view battery usage history, which shows on which days the battery was used and when it started charging. For example, if a battery was installed on 21-08-2025 and used from 28-08-2025, the report records all this information.
