Replacement HP Laptop Batteries

Replacement Batteries for HP Laptops

HP's laptop lineup spans more product lines than almost any other manufacturer — from budget student notebooks to enterprise workstations and gaming rigs. We carry replacement batteries across HP's consumer, business, and gaming lines, covering both current models and older generations that are no longer sold new but still very much in use.

HP Laptop Lines We Cover

• HP Pavilion — HP's longest-running consumer laptop line, covering everyday notebooks in a wide range of sizes and price points
• HP Envy — mid-to-premium consumer laptops aimed at creators and professionals, including the popular Envy x360 convertible
• HP Spectre — HP's former flagship premium ultrabook line, including the Spectre x360; now replaced by OmniBook Ultra in HP's current lineup
• HP OmniBook — HP's current consumer laptop brand, introduced in 2024 as the replacement for the Pavilion, Envy, and Spectre lines
• HP EliteBook — HP's business-grade laptop line, built for enterprise use with enhanced security and durability features

• HP ZBook — mobile workstations for engineers, designers, and other professionals who need desktop-class performance in a laptop
• HP OMEN — HP's gaming laptop line, covering high-performance models for demanding games and applications
• HP Victus — HP's entry-level gaming laptop line, offering gaming performance at a more accessible price point

A Note on HP's 2024 Rebrand

In mid-2024, HP retired the Pavilion, Envy, and Spectre brand names for new models going forward, replacing them with the OmniBook lineup. The OmniBook 3, 5, and 7 correspond roughly to the old Pavilion and Envy tiers, while OmniBook X and OmniBook Ultra replace the Spectre line. If you have a laptop bought before 2024, it will still carry its original Pavilion, Envy, or Spectre name — search by that name or by your battery part number and you'll find the right replacement. If you have a newer OmniBook, search by model name or battery part number the same way.

How to Find the Right HP Laptop Battery

HP battery part numbers are printed on the battery label and follow a consistent format — typically two or three letters followed by two digits and two more letters, often ending in XL for higher capacity versions. Common examples include formats like TF03XL, HT03XL, MU06, and WD549AA. This part number is the most precise identifier and the fastest way to find an exact match in our listings.

If you'd rather search by laptop model, use the filter on this page to browse by model name or number. Your laptop's model number is printed on a sticker on the bottom of the machine. Keep in mind that HP has released many generations of their major product lines — an EliteBook 840, for example, has had over a dozen generations — and battery requirements vary between them. Confirming the battery part number when possible is always the safer approach.

What to Expect from an OEM-Equivalent HP Battery

OEM-equivalent means our replacement batteries are manufactured to match the original HP battery's specifications — same voltage, same watt-hour (Wh) capacity, and same physical connector. The replacement battery charges and discharges through your laptop's built-in battery management system the same way the original did, and your laptop's battery indicator will read it accurately.

HP replacement batteries sold directly through HP can carry a significant price premium over third-party equivalents built to the same specifications. Our batteries offer a warranty-backed alternative at a more practical price point for laptops that are otherwise in good working order.

Signs Your HP Laptop Battery Needs Replacing

• Runtime has dropped significantly — the laptop lasts an hour or two where it used to last most of a workday
• Windows displays a "Consider replacing your battery" warning in the taskbar or Settings
• The battery percentage drops suddenly or jumps erratically under normal use
• The laptop shuts down unexpectedly before the battery indicator reaches zero
• The battery charges to 100% but drains unusually fast under light load
• The battery is visibly swollen — a serious issue that warrants immediate replacement

Windows users can generate a detailed battery health report by opening a command prompt and running powercfg /batteryreport. The report shows your battery's current full charge capacity compared to its original design capacity, giving you a clear picture of how much capacity has been lost over time. HP also offers a built-in Battery Check tool through the HP Support Assistant software, which provides a quick health assessment and recommended action.

How Laptop Battery Replacement Works

The replacement process for HP laptops varies by model and generation:

• Older HP models with removable batteries — the battery slides or clicks out of the bottom of the laptop with no tools required; common on older Pavilion and ProBook models
• Newer HP models with internal batteries — requires removing the bottom panel (typically secured by Phillips-head screws), disconnecting the battery cable, and replacing the battery pack inside the chassis; standard on current Envy, Spectre, EliteBook, and most other modern HP lines

iFixit maintains free repair guides for many HP laptop models with step-by-step photos. HP's own support site also provides service manuals for most current models. If you're not comfortable opening your laptop, a local repair shop can typically handle a battery swap quickly and at a reasonable cost.

A Note on Battery Safety

Laptop batteries store a significant amount of energy in a compact package. If your HP laptop battery is visibly swollen, produces a burning smell, or runs unusually hot during normal use, stop using the laptop and replace the battery before continuing. A swollen battery should be handled carefully — do not puncture or compress it, and dispose of it at a proper battery recycling location rather than in household trash. Most local recycling centers and electronics retailers accept lithium-ion batteries at no charge.

Frequently Asked Questions

Are your HP batteries OEM or aftermarket?

Our replacement batteries are aftermarket — not made by HP, but manufactured to match the original battery's voltage, watt-hour capacity, and connector type. They are recognized by your laptop's battery management system the same way the original was and are backed by a 1-year warranty.

How do I find my HP battery part number?

On laptops with removable batteries, the part number is printed on the battery label — slide or click the battery out of the bottom of the laptop to access it. On laptops with internal batteries, you may need to remove the bottom panel to see the label, or look up your laptop's service manual on HP's support site, which lists the battery part number for your specific model. You can also find the part number in HP Support Assistant under the device specifications for your laptop.

Will my HP laptop recognize an aftermarket battery?

In most cases, yes. HP laptops use standard battery communication protocols that aftermarket batteries support. Some HP models — particularly certain EliteBook and ProBook configurations — may display a battery authentication warning on first boot with a non-HP battery. This is an informational message and does not prevent the battery from charging or functioning normally in the vast majority of cases.

How long will a replacement HP battery last?

Under typical use, a replacement lithium-ion laptop battery will deliver 2 to 4 years of service before capacity starts declining noticeably. Keeping your laptop in a cool environment, avoiding consistently charging to 100% when primarily working plugged in, and not leaving the battery fully discharged for extended periods all help extend lifespan. HP laptops with the HP Battery Care function in BIOS settings can be configured to limit maximum charge to 80%, which is useful for extending long-term battery health on machines that spend most of their time plugged in.

Do you carry replacement chargers for HP laptops?

Yes, we carry replacement chargers for a selection of HP laptop models. Our charger inventory is more limited than our battery selection, but if you need a replacement charger alongside your battery, browse the listings on this page or contact us to check availability for your specific model.

Will an aftermarket battery void my HP warranty?

Under the Magnuson-Moss Warranty Act, manufacturers generally cannot void a product warranty solely because a third-party replacement part was used. If your HP laptop is still within its original warranty period, it's worth reviewing the warranty terms before replacing the battery yourself.

What does the 1-year warranty cover?

The warranty covers defects in materials and workmanship under normal use. If a battery arrives damaged or fails to hold a charge within the warranty period, contact our customer service team at 1-800-405-2121 or online and we'll take care of it.
