Where to Find the Model Number on Your Battery
The easiest way to find your HP laptop battery model number is to remove the battery and read the label on its back or bottom. Most HP batteries have a white or silver label with printed text that includes the model number, serial number, voltage, and capacity. The model number typically starts with letters like "PR" or "HP" followed by numbers — for example, "PR06" or "HSTNN-LB72".
If your laptop has a non-removable battery, you will need to check the information through your operating system or BIOS instead. The label method works only if you can physically access the battery, which is possible on most older and mid-range HP models but not on newer ultrabooks or premium laptops.
Key Takeaways
- Removable batteries have a printed label on the back or bottom that shows the model number, usually starting with "PR" or "HSTNN".
- Non-removable batteries require you to check the model number through Windows settings, the BIOS, or HP's system information tool.
- Your laptop model number and serial number can help you find the correct battery if the battery label is worn or missing.
- HP's support website lets you enter your laptop model to see which batteries are compatible and their exact part numbers.
Checking Battery Information in Windows
Open the Settings app and go to System, then About. Scroll down to find your device name and model number — this is your laptop model, not your battery model. Write this down; you will need it to search for battery information on HP's website.
For more detailed battery information, right-click the battery icon in your system tray (bottom right corner) and select "Battery settings" or "Power settings." This shows your battery health and capacity but usually not the model number. To see the actual battery model, you will need to use the Command Prompt or check the BIOS.
Using Command Prompt to Find the Battery Model
Press the Windows key and type "Command Prompt," then right-click and select "Run as administrator." In the window that opens, type this command exactly: wmic batt get name and press Enter. The output will show your battery model number in a format like "HSTNN-LB72" or "PR06".
If that command does not work, try powercfg /batteryreport instead. This creates an HTML file on your desktop called "battery-report.html." Open it in your web browser and look for the "Design Capacity" and "Full Charge Capacity" sections, which will also list the battery name or model number near the top of the report.
Checking the BIOS for Battery Details
Restart your laptop and press F10 or Esc during startup (the exact key depends on your HP model — check the boot screen). This opens the BIOS menu. Look for a section called "System Information," "Main," or "Power." Some HP BIOS versions display the battery model number here, though not all do.
If you do not see battery information in the BIOS, exit without saving changes by pressing Esc and try one of the other methods instead. The BIOS route works on some HP models but is not reliable across all generations.
Finding the Battery Model Through HP Support
Go to HP's official support website and enter your laptop model number in the search box. Once you find your laptop's support page, look for "Replacement Parts" or "Accessories." HP lists all compatible batteries for your model with their exact part numbers and model names. This is the most reliable way to confirm which battery belongs in your laptop, even if you cannot read the label on the current battery.
You can also call HP support directly with your laptop's serial number and model number. They can tell you the battery model number over the phone and confirm whether your current battery is the original or a replacement. The serial number is usually printed on a sticker on the bottom of your laptop.
What to Do If the Battery Label Is Worn or Missing
If the label on a removable battery is faded or damaged, use your laptop model number to look up the battery on HP's website instead. Your laptop model is printed on a sticker on the bottom of the device or in the Settings app under System > About. Once you have the laptop model, HP's parts list will show you the correct battery model.
If you have already replaced the battery and do not know what model is currently installed, the Command Prompt method or HP support lookup by laptop model is your best option. Do not guess — using the wrong battery can damage your laptop or create a safety hazard.
Frequently Asked Questions
Where is the battery label located on HP laptops?
On removable batteries, the label is on the back or bottom surface. You will see a white or silver sticker with printed text including the model number, voltage, and capacity. The label is usually about 2 inches long and contains multiple lines of information.
What does an HP battery model number look like?
HP battery model numbers typically start with "PR" or "HSTNN" followed by numbers and sometimes letters — for example, "PR06," "HSTNN-LB72," or "RE03." Some older models use different formats. The model number is always printed on the battery label and is different from the serial number.
Can I find the battery model number if my laptop battery is built in?
Yes. Use the Command Prompt method (wmic batt get name) or the battery report tool (powercfg /batteryreport) to see the model name. You can also enter your laptop model on HP's support website to see which battery is installed in that model.
Is the battery model number the same as the laptop model number?
No. Your laptop model number (like "HP Pavilion 15-ab123nr") is different from your battery model number (like "HSTNN-LB72"). One laptop model may use multiple battery options, so you need the battery model specifically to order a replacement.
What if the Command Prompt command does not show my battery model?
Try the battery report method instead (powercfg /batteryreport). If neither works, your laptop may not store the battery model in a way Windows can read. In that case, check the physical label on the battery or contact HP support with your laptop model number and serial number.
