HP Notebook PCs - Purchasing a Replacement Battery
The battery in a notebook PC is designed to provide dependable power; however, all rechargeable batteries gradually lose their capacity to hold a charge. Batteries made of different materials have different lifecycles. For instance, with moderate use, Li-Ion batteries are expected to deliver around 80% of their original capacity after 300 charge cycles or about one year of use. This loss in capacity (aging) is normal and irreversible.
Test the condition of an HP Notebook PC battery
HP provides a battery check tool you can use to test your battery before ordering a new one. For instructions on testing the condition of your battery, see:
Find the notebook product number
Different notebook models require different batteries. Before ordering a battery, you need to know the product number of your notebook to determine the part number of the replacement battery. To find your product number, use HP Support Assistant or locate the product number on the product label.
To locate the product number using HP Support Assistant, download and install the latest version of the HP Support Assistant software.
In Windows, search for and open HP Support Assistant. When HP Support Assistant opens, the product name, product number, and serial number of the notebook are displayed at the bottom of the window.
To locate notebook product number using the product label, see HP Notebook PCs - How Do I Find My Model Number or Product Number?.
With the notebook powered off, turn the notebook over and locate the HP product label on the bottom of the notebook. The product number (P/N) is printed on this tag.
note:On some models, the product tag may be located inside a battery compartment or behind an access panel.
Order a replacement battery online through the HP Parts Store
After you have found the product number of the notebook and have tested the condition of the battery, perform the following steps to order a new battery.
note:Some countries/regions may not be supported when ordering parts from HP.com. See your local HP retailer or contact HP directly to purchase additional batteries or other parts.
Go to the HP Parts Store.
Under Buy certified HP genuine replacement parts, select the desired country/region and language.
Type your Serial Number, Product number, or Product name in the field and click the Search for a part button.
note:If you are using the product number to search, remove the suffix from the product number. For example, product number DZ357U#ABA is entered as DZ357U.
Find your notebook and then click the appropriate product number.
Find the battery in the part list and follow the on-screen instructions to purchase the battery from HP or from HP Parts Store partners.
