The Battery Report is a utility that is part of the Windows OS that can help provide an understanding of the remaining life your laptop battery has.

To invoke the report, hold down the Windows key and tap the X key once. Click on Terminal(Admin) in the menu to open a command terminal window. In the windows, type in powercfg /batteryreport and press the enter key.

Now open the Windows Explorer and type Battery-report.html in the search box at the upper right and press enter.

The location of your Battery-report file will appear as in the image below.

Double click the Battery-report.html file and select a browser of your choice as the app to open the file.

Now you will see the report.

You can print it if you like, or copy the text and post it in a reply in a thread you may have authored about your battery issue.

Your original laptop battery will also show the serial number and number of charge/discharge cycles in the Cycle Count. Mine is a replacement, so it does not.

 

This is the part of the report that will help you make an educated decision on replacing the battery.

The following information is from online industry sources
"The life of a laptop battery is approximately between 300-500 cycles." Under normal usage conditions and in ambient temperatures (25°C), the Li-ion battery is expected to charge and discharge normally for 300 cycles (or about one year)." That is the reason that the industry wide warranty for a laptop battery is one year. The average laptop battery can last between 2-5 years or between 300-500 cycles. That depends on the type of use, the power management setting and how often the laptop is used."

 

The Battery Care option present in most HP laptop BIOS is recommended to be set at 80%. Doing that does extend the service life of the battery.

 

As your battery ages, its Full Charge Capacity will diminish over time.

When Full Charge Capacity is 70% or less than the Design capacity, you will begin to notice that you will have reduced mobile, or stand alone use of the laptop without the power adapter connected.

At a certain point, usually between 30-50% of the Design capacity, The battery reaches a bit of a tipping point in its product life cycle.

 

You will find that at lower full charge capacity, the battery drains quickly. It may even surprise you and shut down the laptop.

 

That is at the point of your laptop's battery life cycle where it should be replaced with a new one.

 

You can, if you have the confidence and are willing to accept the risk, change the battery yourself.

 

There are disassembly videos on YouTube and  in the YouTube HP Support Channel for most laptops.

 

The YouTube HP Support Channel has many remove and replace parts videos  for HP laptops.

Use the generic Product name found on the bottom of your laptop when searching for a video.

 

If you do not have the confidence and are not willing to risk damaging your laptop, it would be best to have the battery changed by a laptop service engineer in a PC or laptop shop.

 

Do be aware that replacing the battery on your own does violate the warranty.
