"You are using an unsupported battery"

[TheBlackAdder]

13. It seems like you have a gray market battery, and something in the laptop software is detecting it.

.

Right Click your Windows icon on the lower left and select Terminal (admin) or Command Prompt (admin or run as admin). You may have a pop-up asking to run as administrator, click it.

Type at the DOS prompt: powercfg /batteryreport

This will create an HTML file with your battery information. The path and file name will be returned.

Go to File Explorer and click on that file.

It will give information such as your laptop info and OS build, then a report on the details of your battery, the name of it, the manufacturer, the serial number, the chemistry, the design capacity, the full charge capacity and the cycle count. Then it gives your recent usage, and I was misspoken, my battery is still at 100% of its capacity. You will see if you got an OEM battery or another one.

As an example, my laptop is 3 years old and it has a cycle count of 406, so I am not even half the way to hitting the charge limit.

Note: The battery manufacturer might not say DELL, but it might be the company Dell subcontracts their batteries, so you need to verify the manufacturer with Dell support to see if it's a legit OEM one.
