Find the Correct HP Laptop Battery with HP Support Assistant
A field-tested workflow to identify the exact battery your HP notebook needs—using HP Support Assistant and Windows tools—plus trusted product picks you can order today.
Why using the right battery matters
HP laptops accept only specific battery packs that match the electrical profile, mechanical footprint, connector, and firmware handshake HP expects. Using a mismatched pack can cause short runtime, charging refusal, or BIOS warnings. The goal is to reliably extract your laptop’s official identifiers and map them to a battery model code (like HT03XL) or a compatible replacement listing.
What you need before you start
- HP Support Assistant (HPSA) installed. Many HP systems include it; if not, install the latest version from HP.
- Windows admin rights to run battery diagnostics (optional but recommended).
- 5–10 minutes of uninterrupted time.
Method A — Use HP Support Assistant
Step 1 — Open HP Support Assistant
Launch HP Support Assistant. On the My devices home, select your laptop tile.
Step 2 — Capture core identifiers
Open Device details or Specifications and note:
- Product Name (e.g., HP Laptop 15-dyXXXXX)
- Product Number / SKU (e.g., xxxxxx#ABA)
- Serial Number (for service lookups if needed)
Step 3 — Run Battery Check
In HPSA, open Battery or Diagnostics and run Battery Check. Record the health result and any battery name displayed. If a battery code appears (e.g., “HP HT03XL”), keep it—this is your direct model code.
Method B — Windows Battery Report (cross-check)
Windows can generate a manufacturer battery report that often includes the ACPI name containing your battery code.
Step 1 — Generate report
Open an elevated Command Prompt and run:
powercfg /batteryreport /output "%USERPROFILE%\Desktop\battery-report.html"Step 2 — Read the battery name
Open the HTML report and locate the “Installed batteries” section. Look for the NAME or MANUFACTURER field; HP packs typically show names like HT03XL, HW03XL, or GD03XL. Note the Design Capacity and Full Charge Capacity for health context.
Identify the battery code (HT03XL, HW03XL, GD03XL, etc.)
The code printed on HP internal batteries (and often surfaced via ACPI) is the quickest way to match a replacement. Use the table below to understand typical design capacities you’ll see when browsing listings.
| Battery Code | Typical Watt-hours (Wh) | Notes |
|---|---|---|
| HT03XL | ≈ 41.04 Wh | Common 3-cell pack for many 14–15″ HP consumer models. |
| HW03XL | ≈ 41.04 Wh | Sibling to HT03XL in similar chassis families; check plug and bracket shape. |
| GD03XL | ≈ 59.16 Wh | Higher-capacity 3-cell pack used by select models; ensure physical fit. |
Verification checklist
- Battery code matches your findings (from HPSA or the Windows report).
- Watt-hours are equal or close to original; higher Wh of the same family is often acceptable if the footprint matches.
- Voltage matches the original pack’s nominal voltage family (typically 11.4V class for these 3-cell models).
- Connector orientation and mounting holes align with your chassis.
- Return and warranty terms are clear; keep your old battery until you fully verify fit and function.
Recommended HP batteries you can buy now
Once you have the battery code, shop the curated HP battery collection below. Each product page lists technical details and compatible models.
HP HW03XL 41.04Wh
Form-factor sibling to HT03XL used in select HP models; verify bracket and cable alignment.
HP GD03XL 59.16Wh
Higher-capacity option where supported; confirm chassis compatibility before ordering.
Install, calibrate, and maintain
Installation essentials
- Shut down, unplug AC, and hold the power button for 15 seconds to discharge.
- Use ESD precautions; avoid metal tools bridging contacts.
- Disconnect the battery cable straight out of the board; avoid twisting the ribbon.
- Route the cable exactly as original to prevent pressure on the palm rest.
First-run calibration
- Charge to 100% on AC, keep it at full for 30–60 minutes.
- Unplug and use the laptop down to 10–15% without forced deep drain.
- Recharge back to 100%. This syncs the gauge and improves runtime estimates.
FAQ
HPSA didn’t show a battery code—now what?
Use the Windows battery report method to extract the NAME field, or open the chassis and read the code printed on the pack itself. Match that code when shopping.
Can I choose a higher-Wh battery of the same family?
Yes—if the model code and mechanical footprint match or the listing explicitly says it replaces your original part number. Higher Wh means longer runtime, not more voltage.
What if the connector looks similar but mirrored?
Do not force it. Many HP cables look alike but are keyed. Order by the exact code and check the product images for connector orientation and screw tabs.
