Fits HP Pavilion DV7, DV7T, DV7Z laptops; replaces OEM part 464059-121, 464059-141, 458058-121, 480385-001, 497705-001, HSTNN-IB74, HSTNN-IB75, HSTNN-C50C, HSTNN-Q35C, HSTNN-DB74, HSTNN-DB75, HSTNN-OB75, KS525AA.
14.4V and 6600mAh capacity delivers 95.04Wh for full daily portable use on the DV7's discrete graphics and multi-core processor.
Connector seats vertically into the battery slot with a pull-release tab on the left side; ensure the latch fully engages before closing the compartment.
We bench-tested against the DV7's fuel gauge IC — the cell held steady voltage delivery under sustained CPU load with no early cutoff.
After installation, run one complete discharge cycle to sleep-mode cutoff, then charge uninterrupted to 100% — this resets the BIOS battery learn cycle and clears inaccurate health warnings that appear after every cell swap on this platform.

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 Pavilion DV7 Series — 14.4V Li-ion Replacement Battery (464059-121)

This is a 14.4V, 6600mAh (95.04Wh) Li-ion battery for the HP Pavilion DV7, DV7T, DV7Z, and DV7T-1000 series laptops. It replaces OEM part numbers including 464059-121, HSTNN-IB74, HSTNN-DB75, and 480385-001 among others. Slide it into the same bay as the original — the connector and latch positions are identical across the DV7 range covered here.

  • DV7 series compatibility: The DV7, DV7T, DV7Z, and DV7T-1000 share the same 14.4V battery rail, connector pinout, and BMS handshake protocol — which is why one part number covers all of them. Swapping between these sub-models does not require any firmware or hardware change.
  • Bench tested on actual hardware: We cycled this cell through full charge and discharge on a DV7 chassis. The BMS communicated correctly with the HP EC firmware, reported charge state without fault codes, and held voltage steady under combined CPU and display load without triggering a protection cutoff.
  • Post-install calibration on the DV7: After fitting this battery, run one full discharge until the laptop hibernates, then charge uninterrupted to 100% without interruption. This resets the BIOS battery learn cycle and clears the inaccurate health warning that shows up after every cell swap on the Pavilion DV7 line.

BIOS reporting poor battery health immediately after fitting a new cell

The HP Pavilion DV7 BIOS reads health data from an EEPROM register that was written by the original factory cell. When a replacement cell arrives, that register does not match the new chemistry data, and the BIOS flags it as degraded. This is a data mismatch, not a cell defect. Running one full discharge-to-hibernate followed by an uninterrupted charge to 100% rewrites the learn cycle and clears the warning. After two or three full cycles the fuel gauge IC re-calibrates and the health readout stabilises.

Laptop shuts down at 20–30% charge shown on screen

This happens when the cell voltage drops below the BMS cutoff threshold under full load — CPU boost plus backlit display draws more current than the fuel gauge IC predicts from a poorly calibrated state-of-charge curve. The percentage shown is based on a stale calibration map, so the real cell voltage hits the cliff before the display reads zero. To fix it, let the laptop discharge fully to hibernate-cutoff at least twice in a row, then charge to 100% each time. After those two cycles the fuel gauge re-maps the voltage curve against the new cell and the shutdown point moves back to below 5%.

Frequently Asked Questions

My HP Pavilion DV7 shows the new battery as "0% available (plugged in, not charging)" — what's wrong?

This is an EEPROM data conflict between the new cell and the HP EC firmware. The BIOS read charge-state data from the old cell's memory and is now seeing mismatched values from the replacement. Shut the laptop down completely, remove the AC adapter, hold the power button for 15 seconds to drain residual EC power, then reconnect AC only and power on. If the charge percentage still reads 0%, run HP's battery check from BIOS (F2 at boot → Battery Test) — a pass there confirms the cell is good and the issue is the fuel gauge IC needing calibration cycles.

The system information panel shows this battery as 47Wh even though the cell is rated 95Wh — is it faulty?

The Wh figure in Windows or HP Support Assistant is pulled from the EEPROM on the old cell's data block, not measured from the new cell directly. The replacement cell carries its own EEPROM with the correct 95.04Wh rating, but the OS can display a cached or misread value until the fuel gauge IC recalibrates. Run two full discharge-to-hibernate cycles followed by uninterrupted charges to 100% each time. After that the reported Wh figure should update to match the actual cell capacity.

The DV7 charges fine but the battery percentage jumps around — reads 74%, then 61%, then 80% within minutes of unplugging.

The fuel gauge IC on the DV7 mainboard estimates state-of-charge by tracking voltage and current draw over time, and after a cell swap its internal map no longer matches the new cell's discharge curve. It is not reading faulty data — it is interpolating from a curve built on the old cell. Two full discharge-to-hibernate cycles, each followed by a charge to 100% without interruption, force the IC to rebuild its curve against the new cell. After those cycles the percentage readout will track smoothly, and swings of more than 3–4% between readings will stop.
