1. Step 1: Find Your Battery Model Number First
Before you go ahead and compare prices or make your choice between an OEM and an aftermarket battery, you need to know one thing: the battery model number. The only reason people end up with the wrong battery is because they order it simply on the basis of the laptop's model name, such as "HP Pavilion battery".
You have four ways to find it:
| Method | What You Need | Reliability |
|---|---|---|
| Read the battery label | Remove the battery (or bottom cover for internal packs) | โ Highest โ what's actually installed |
| Windows battery report | Open CMD, run powercfg /batteryreport
|
โ High โ no disassembly needed |
| HP Support Assistant | Pre-installed on most HP laptops | โ High โ reads from firmware |
| HP PartSurfer | Laptop serial number (bottom label) | โ ๏ธ Shows factory battery, not current one |
The model number will be one of the following: HT03XL, LK03XL, SR04XL, JC04, HSTNN-LB6M, or L11119-855. Copy it exactly since that code is your ticket to a battery which fits.

How to Find Your HP Battery Model Number โ2. Step 2: OEM vs. Aftermarket โ Which Should You Choose?
After you have your model number, you have to decide whether to go for an HP original (OEM) battery or a compatible after-market one. Both types have their advantages. The following is an honest comparison:
| OEM (HP Original) | Premium Aftermarket | Budget Aftermarket | |
|---|---|---|---|
| Price | $80โ$150 | $40โ$90 | $25โ$50 |
| Warranty | 1 year (HP) | 6โ12 months | 3 months or none |
| Lifespan | 2โ3 years | 1โ2 years | 6 monthsโ1 year |
| Runtime | Matches original spec | Close to spec | Often 1โ2 hours less |
| Safety certs | UL, CE, FCC | CE, FCC (check listing) | Often uncertified |
| BIOS warnings | None | Rare (some Spectre/EliteBook) | Common on business models |
In fact, the best choice for the average person is to buy premium after-market batteries from trustworthy sellers since these cost only half of what HP prices them and work almost as well as the original ones, provided that you purchase from a seller who gives the exact specifications and has a genuine warranty behind them.
It makes more sense in two cases: when your laptop is still covered by HP's warranty and you don't want to take that risk, or when you have a high-end business machine (such as an EliteBook or a Spectre) since BIOS battery warnings are more frequently encountered with third-party battery packs.
The budget aftermarket batteriesโthose listed at $25 with general descriptions and no warrantyโaren't worth the risk; when a battery fails the best that can happen is that it stops holding a charge, while the worst outcome is that it swells and damages your laptop.
3. Step 3: The 4 Specs That Must Match
Not all specs are equally important. Here's the hierarchy:
| Spec | How Strict? | What Happens If You Get It Wrong |
|---|---|---|
| 1. Voltage (V) | ๐ด Must match exactly | Wrong voltage = laptop won't power on, or worse, it can damage the charging circuit |
| 2. Connector type & position | ๐ด Must match exactly | Won't plug in. Different HP models use different pin layouts even within the same series |
| 3. Physical dimensions | ๐ก Must fit the chassis | Screw holes won't align. Too thick = bottom cover won't close |
| 4. Capacity (Wh) | ๐ข Same or higher is fine | Higher Wh = longer runtime. As long as voltage and dimensions match, more capacity is better |
You can't change the voltage. If the battery you have originally is 11.55 volts, the replacement had better be 11.55 volts โ not 10.8 volts, not 14.8 volts. I've heard of people attempting to use a 14.8-volt battery in an appliance that takes 11.55 volts because it was cheaper, but the laptop wouldn't recognise it.
On the other hand, capacity (measured in watt-hours or Wh) can be increased. If the original battery is 41Wh and there is available a 52.5Wh version with the same voltage, connector, and shape, then you should choose the one with the higher capacity as this will give you about 25% more runtime.
4. HP Battery Quick Lookup by Series
The following table lists the battery models most commonly associated with various HP laptop series. It can be used to narrow down your search, but you should check the exact model number on your present battery.
| HP Series | Common Battery Models | Typical Voltage | Capacity Range |
|---|---|---|---|
| Pavilion 14/15/17 | HT03XL, HW03XL, LK03XL, BP02XL | 11.55V | 37โ52.5Wh |
| Pavilion Gaming | SR04XL, KI04 | 15.4V | 70Wh |
| Pavilion x360 | LK03XL, HW03XL | 11.55V | 41โ52.5Wh |
| EliteBook 830/840/850 G5โG8 | SS03XL, CC03XL | 11.55V | 50โ56Wh |
| ProBook 400/600 | RI04, RI04XL | 14.4V | 40โ56Wh |
| Envy 13/15/17 | LK03XL, HSTNN-LB7U | 11.55V | 51โ55Wh |
| Spectre x360 | PK03XL | 11.4V | 60โ83Wh |
| OMEN 15/16/17 | SR04XL, WK06XL, PF06XL | 11.55V / 15.4V | 70โ96Wh |
| Victus 15/16 | SR04XL (varies by config) | 15.4V | 52โ70Wh |
โ ๏ธ Important: This table shows the most common batteries per series, not every possible configuration. HP sometimes changes battery models mid-production. Always verify with your actual battery label or HP PartSurfer before ordering.
5. Where to Buy: Sources Compared
| Source | Price Range | Warranty | Risk Level |
|---|---|---|---|
| HP Official Store | $80โ$150 | 1 year (HP) | ๐ข Lowest |
| Specialist battery retailers | $40โ$110 | 12 months (typical) | ๐ข Low โ curated stock, specs listed |
| Amazon (rated sellers) | $30โ$90 | Varies (3โ12 months) | ๐ก Moderate, check reviews carefully |
| eBay / AliExpress | $15โ$60 | Often none | ๐ด High, counterfeit risk |
On the basis of my experience, specialist retailers who sell batteries provide the most satisfactory combination of price, warranty, and reliability; they carry their batteries by model number (not just by the name of the laptop), state the actual voltage and capacity, and have a genuine return policy. Whereas if you purchase from a general marketplace you are having to depend on the seller giving accurate information about the specifications, and some sellers do not do so.
6. How Much Should You Pay? Price Guide by Series
Prices vary by capacity and series. Here's what to expect for a quality aftermarket replacement in 2025โ2026:
| HP Series | Battery Example | Capacity | Fair Price (Aftermarket) |
|---|---|---|---|
| Pavilion (standard) | HT03XL, HW03XL | 41โ52.5Wh | $45โ$65 |
| Pavilion (extended) | LK03XL | 52.5Wh | $55โ$80 |
| EliteBook / ProBook | SS03XL, CC03XL, RI04 | 50โ56Wh | $50โ$75 |
| Envy / Spectre | LK03XL, PK03XL | 51โ83Wh | $55โ$110 |
| OMEN / Victus (gaming) | SR04XL, WK06XL | 70โ96Wh | $65โ$120 |
If a price turns out to be well below these figuresโfor example, a 70Wh OMEN battery being offered for $25โthen that isn't a good deal; it's a battery that has used up recycled cells, missing protection circuits, or perhaps both. There's a reason why there is a price floor: quality lithium-ion cells, a suitable BMS (battery management system), and safety certifications all involve costs.
7. What to Expect After Installation
A new battery doesn't always report perfectly right out of the box. Here's what's normal and what's not:
| Situation | Normal? | What to Do |
|---|---|---|
| Battery shows 0% on first boot | โ Normal, it ships in storage mode | Charge to 100%, leave plugged in 30 extra minutes |
| Windows shows "plugged in, not charging" | โ ๏ธ Sometimes normal on first connection | Reseat the battery connector. Update BIOS and chipset drivers |
| Battery percentage jumps around | โ Normal for first 1โ2 cycles | Run one full discharge (to 10%) and recharge to calibrate |
| Runtime is lower than expected | โ ๏ธ May need calibration | Complete 2โ3 full charge/discharge cycles. If still low after a week, contact the seller |
| BIOS shows "non-genuine battery" warning | โ ๏ธ Common on EliteBook/Spectre with aftermarket | Usually harmless, press Enter to continue. Battery still charges and functions |
I have found that new batteries usually don't display their actual runtime on the first day; instead, they generally require only one or two full cycles to settle down. Therefore, you should use the battery normally for a week before assessing its runtime.

OEM vs. Aftermarket HP Batteries: Full Comparison โFrequently Asked Questions
Is it worth replacing an HP laptop battery?
In most cases, yes. If your laptop is less than 5โ6 years old and otherwise runs well, a $50โ$100 battery gives you back portability and prevents sudden shutdowns. It costs far less than a new laptop. If the laptop also has major issues (failing motherboard, cracked screen, dead SSD), the equation changes, but if the battery is the only problem, replacing it is almost always worth it.
How do I know which battery to buy for my HP laptop?
You need the battery model number from your current battery, a code like HT03XL, LK03XL, or SR04XL. You can find it on the battery label itself, through the Windows battery report (run powercfg /batteryreport in Command Prompt), or via HP Support Assistant. Never buy based on laptop model name alone. A single laptop series can use multiple different batteries.
OEM vs. aftermarket, which is better?
OEM batteries are the safest choice: guaranteed compatibility, full HP warranty support, and the longest expected lifespan (2โ3 years). Premium aftermarket batteries from reputable sellers cost 40โ60% less and perform close to OEM specs, making them the best value for most people. Budget aftermarket batteries (under $30) should be avoided: they often use lower-quality cells, lack safety certifications, and fail within months.
Can I use a higher capacity battery in my HP laptop?
Yes, as long as the voltage, connector, and physical dimensions match your original. A higher Wh rating simply means longer runtime. For example, if your Pavilion shipped with a 41Wh HT03XL, you can often upgrade to a 52.5Wh LK03XL if the form factor and connector are the same. Always confirm compatibility with the seller before ordering.
How much does an HP laptop battery replacement cost?
For a quality aftermarket replacement: $45โ$65 for standard Pavilion batteries, $50โ$75 for EliteBook/ProBook, $55โ$110 for Envy/Spectre, and $65โ$120 for high-capacity OMEN gaming batteries. OEM batteries from HP cost roughly double across all categories. Add $60โ$120 if you pay a repair shop for installation.
Will a third-party battery void my HP warranty?
No, using a third-party battery does not automatically void your HP laptop warranty. Under the Magnuson-Moss Warranty Act, a manufacturer cannot void your warranty simply because you used a non-OEM part. However, if the third-party battery causes damage to the laptop, HP may not cover that specific damage. Always keep your original battery, you can reinstall it before warranty service if needed.
