Up to 17% off
New arrival
From $123.99 USD $148.99
Shipping calculated at checkout.
Fits HP ZBook 15 G3, ZBook 17 G3, and ZBook 15 G4 laptops; replaces HSTNN-DB7D, VV09XL, and 808398-2C1 battery part numbers.
11.4V and 7700mAh capacity delivers 87.78Wh total; matches OEM output for full CPU and discrete GPU load on mobile workstations.
Connector attaches via single-pin latch at base of battery slot; physical dimensions match original housing exactly, no modification needed.
We bench-tested the cell on ZBook 15 G3 motherboard; BMS responded normally to full charge cycle and reported accurate capacity to BIOS on first insertion.
After installation, run one complete discharge to hibernation-cutoff then charge uninterrupted to 100% — this resets the BIOS battery learn cycle and clears the 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 ZBook 15 G3 / ZBook 17 G3 — 11.4V Li-Polymer Replacement Battery (HSTNN-DB7D)

This is an 11.4V, 7700mAh (87.78Wh) Li-Polymer replacement battery for the HP ZBook 15 G3 and ZBook 17 G3 mobile workstations, along with the ZBook 15 G4. It replaces OEM part numbers including HSTNN-DB7D, VV09XL, and 808452-001. Install it when the original cell no longer holds charge under CPU or display load.

  • ZBook 15 and 17 G3/G4 compatibility: These models share the same 11.4V three-cell Li-Polymer architecture, identical connector pinout, and the same BMS handshake protocol — which is why one cell serves all three platforms without firmware conflict.
  • Bench tested on actual hardware: We ran this cell on a ZBook 15 G3 under sustained CPU load. The BMS held voltage above the 10.0V cutoff threshold throughout the discharge cycle and accepted a full charge without triggering the BIOS health fault flag on the first cycle.
  • Post-install calibration on ZBook workstations: After fitting this cell, run the laptop on battery until it hibernates from low charge, then charge uninterrupted to 100% before next use. This completes the BIOS battery learn cycle and clears the inaccurate "replace battery" warning that nearly always appears after a cell swap on HP ZBook firmware.

Why the ZBook 15 G3 shuts down at 20–30% shown after a battery swap

Under full workstation load — CPU at sustained boost, display at full brightness, discrete GPU active — the cell voltage drops faster than the fuel gauge IC can track. The BIOS reaches its undervoltage protection threshold before the displayed percentage reaches zero. This is a voltage cliff event, not a firmware bug. The new cell's EEPROM data needs at least two full discharge-to-charge cycles before the fuel gauge IC maps the actual capacity curve of the replacement chemistry. After two complete cycles, the shutdown point stabilises to within a few percent of actual remaining charge.

BIOS reporting the battery Wh rating as incorrect after cell replacement

The ZBook BIOS reads Wh rating directly from the cell's EEPROM at POST. If the replacement cell's EEPROM carries a different rated value than the original — even when actual chemistry matches — the system information screen will show a mismatched Wh figure. This is an EEPROM metadata difference, not a capacity fault. The cell will still charge and discharge correctly. To confirm actual capacity, check the HP Support Assistant battery report after two full calibration cycles rather than relying on the POST-reported Wh value.

Frequently Asked Questions

The ZBook 15 G3 BIOS says "Unknown Battery" or shows 0% immediately after I installed the new cell — what's wrong?

The BIOS pulls cell identity from the EEPROM on first boot. When the old cell's EEPROM data is gone and the new cell hasn't completed a learn cycle, the firmware logs it as unknown. Charge the new cell to 100% uninterrupted, then discharge fully to hibernate — do not interrupt either phase. After one complete cycle, the BIOS re-reads the EEPROM correctly and clears the unknown status. If it persists past two cycles, confirm the cell voltage reads above 10.8V at rest with a multimeter.

The fuel gauge jumps from 60% to 90% and back while the ZBook is unplugged — is the cell faulty?

The fuel gauge IC calibrates its capacity model against the new cell's actual discharge curve, which takes several cycles to settle. Until it maps the curve, percentage readings swing wildly because the IC is still using the old cell's reference data. Run three complete discharge-to-hibernate and full-charge cycles without interruption. By the third cycle, the gauge IC has enough data points to track the new chemistry accurately and the percentage display stabilises.

The ZBook 15 G3 stops charging at exactly 80% every time — did we get a defective battery?

This is almost always HP's Battery Care Advisor firmware feature, not a cell fault. HP BIOS on ZBook workstations includes an 80% charge limit mode that activates when the laptop is frequently left plugged in. Open HP Support Assistant, go to Battery settings, and confirm whether the charge limit is enabled. Disable it, then plug in and verify charging resumes past 80%. The cell itself is not at fault — it will accept a full charge once the firmware limit is cleared.
