HP EliteBook 2560p Replacement Battery HSTNN-DB2L 11.1V 4400mAh

Up to 20% off
New arrival
From $68.99 USD $85.99
Shipping calculated at checkout.
Fits HP EliteBook 2560p and 2570p laptops replacing OEM part numbers HSTNN-DB2L, HSTNN-DB2M, HSTNN-I08C, 632423-001, and compatible equivalents.
11.1V 4400mAh capacity restores full runtime on the EliteBook platform after original cell degradation or physical damage.
Connector slides straight into the battery bay with latching tabs on both sides — no force needed, seats flush.
We bench-tested this pack on a 2560p motherboard; the fuel gauge IC accepted the new cell and calibrated charge capacity across two cycles.
After installation, run one full discharge to hibernation cutoff then charge uninterrupted to 100% — this resets the BIOS battery learn cycle and clears inaccurate health warnings that appear after every cell swap.

It took a bit longer than expected, likely due to the holiday season, but that was understandable. So far, the battery seems to be working well!

Battery Care Tips

🔹 Getting Started

Charge your new battery fully before you use it for the first time. Over the next few charge cycles, run your device down to around 20% before you recharge—this helps the battery perform its best. After that, charge whenever you need to.

🔹 Keep It Healthy

Avoid letting your battery completely drain or staying plugged in constantly. Both extremes wear it out faster. Store the battery in a cool, dry place when you're not using it, since heat damages batteries quickly.

Delivery and Shipping

🔹 Most orders ship the next day, and we use FedEx, UPS, Purolator and other carriers to get them to you. Lithium batteries have to ship by ground only, not air or USPS. Make sure your address is right before you order, because if we have to send it back, you pay for shipping again.

HP EliteBook 2560p / 2570p — 11.1V Li-ion Replacement Battery (HSTNN-DB2L)

This is an 11.1V, 4400mAh (48.84Wh) Li-ion replacement battery for the HP EliteBook 2560p and EliteBook 2570p laptops. It replaces original cells that have degraded, failed to hold charge, or dropped to unusable capacity. Fits the OEM part numbers HSTNN-DB2L, HSTNN-DB2M, HSTNN-I08C, 632423-001, and the full SX03/SX06/SX09 series.

  • EliteBook 2560p and 2570p compatibility: Both models share the same 11.1V three-cell architecture, battery connector pinout, and BMS handshake protocol. That is why a single part number covers both — the BIOS reads the same EEPROM data from either battery without needing a firmware change.
  • Bench tested on actual hardware: We ran this cell on an EliteBook 2560p under combined CPU and display load. The BMS held the voltage rail stable through the full discharge curve. No unexpected cutoffs were triggered at mid-charge states.
  • Post-install calibration tip for the 2560p and 2570p: After installing, run one full discharge to hibernate-cutoff, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears on the first boot after every cell swap.

BIOS reporting poor battery health immediately after replacement

The HP EliteBook BIOS reads health data from the battery's EEPROM chip, not from live voltage measurements. When a new cell goes in, the EEPROM carries default factory data that the BIOS interprets as degraded or unknown. This is a data mismatch, not a fault with the replacement cell. Running the BIOS battery learn cycle — one full discharge to hibernate, then an uninterrupted charge to 100% — rewrites the health registers and clears the warning. After two full cycles, the BIOS typically reports normal status.

EliteBook 2560p shutting down at 20–30% charge shown on screen

This happens when the fuel gauge IC has not yet calibrated against the new cell's actual voltage curve. The laptop shuts down because the real cell voltage hits the hardware cutoff while the OS gauge still shows 20–30% remaining — the two are out of sync. It is not a cell defect. Run two full discharge-to-hibernate and charge-to-100% cycles without interruption. After the second cycle, the fuel gauge recalibrates and the shutdown threshold aligns to the correct voltage floor of approximately 9.0V.

Frequently Asked Questions

My HP EliteBook 2560p BIOS says the new battery has 0Wh or shows the wrong watt-hour rating in system information — is the cell faulty?

The Wh figure in HP's system info is pulled from the battery's EEPROM, which stores the OEM-rated value at manufacture. New replacement cells carry their own EEPROM data, which can differ from what HP's firmware expects and display as an incorrect or zero Wh reading. This is an EEPROM data mismatch, not a capacity defect — the cell still delivers its full 48.84Wh in use. Run the BIOS battery learn cycle (full discharge to hibernate, full uninterrupted charge to 100%) and the displayed value typically corrects itself after one or two cycles.

The charge on my EliteBook 2560p stops at 80% and won't go higher — did I get a faulty battery?

HP EliteBook firmware includes a BIOS-controlled charge limit that caps charging at 80% when Battery Health Manager is active. This is a firmware setting, not a fault with the replacement cell. Open HP Support Assistant, navigate to Battery Health Manager, and switch the mode from "Maximize my battery health" to "Let HP manage my battery's charge." The cell will then charge to 100%.

After swapping the battery in my EliteBook 2570p, the OS fuel gauge jumps around wildly — showing 95%, then dropping to 60%, then climbing again. What is causing this?

The fuel gauge IC on the EliteBook 2570p learns the new cell's voltage curve over several discharge cycles. Until that calibration is complete, the reported percentage drifts significantly because the IC is still using the old cell's reference data. This is expected behaviour for the first two to three cycles and does not indicate a defect. Run two complete discharge-to-hibernate and uninterrupted charge-to-100% cycles, and the gauge will stabilise to within a few percent of actual charge state.
