From $96.99 USD $119.99
Shipping calculated at checkout.
Fits HP ZBook Studio G3 V8N25PA and G4 models; replaces OEM part 2N08XL and equivalent part numbers.
This 15.4V 5850mAh Li-Polymer cell delivers 90.09Wh—sufficient for full workday operation on creative and engineering tasks.
Connector slides straight in; locking tab seats flush against the battery compartment wall without forcing.
We bench tested this cell against the ZBook Studio G4 charger; BMS accepted handshake on first insertion and charged to full without throttling.
After installation, discharge completely to hibernate cutoff then charge uninterrupted to 100%—this resets the BIOS battery learn cycle and clears false health warnings.

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 Studio G3/G4 Series — 15.4V Li-Polymer Replacement Battery (2N08XL)

This 15.4V, 5850mAh (90.09Wh) Li-Polymer cell replaces the original 2N08XL battery in the HP ZBook Studio G3 and G4 mobile workstations. It fits the V8N25PA, Y6K33EA, 1RR16EA, and related Studio G3/G4 variants. OEM part numbers covered include 907428-2C1, 907584-850, 907584-852, HSN-C02C, HSTNN-DB7U, and ZN08XL.

  • ZBook Studio G3 and G4 platform fit: Both generations use the same 15.4V four-cell Li-Polymer pack, the same HSN-C02C connector footprint, and the same BMS handshake protocol — which is why a single replacement cell covers the entire Studio G3/G4 range without modification.
  • Bench tested on actual hardware: We cycled this cell on a ZBook Studio G3 chassis and confirmed the BMS initialised correctly, the BIOS accepted the EEPROM data, and charge current tapered properly through CC/CV stages without fault codes.
  • ZBook battery learn cycle after install: After fitting, discharge the laptop to hibernate cutoff under normal workstation load — GPU and CPU both active — then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning the firmware posts after every cell swap.

BIOS reporting poor battery health immediately after replacement

HP's ZBook firmware stores learned capacity data from the previous cell in its battery learn table. When a new cell is fitted, the BIOS compares the incoming EEPROM values against that stored table and flags a mismatch as degraded health. This is a firmware calibration state, not a battery fault. Run one full discharge-to-hibernate followed by an uninterrupted charge to 100% — the BIOS resets its learn cycle and the health warning clears within two to three cycles.

Laptop shutting down at 20–30% charge shown on new cell

This is a voltage cliff issue, not a capacity problem. Under full ZBook load — discrete GPU rendering, sustained CPU boost, and a high-brightness display — the cell voltage drops faster than the fuel gauge IC can recalibrate. The BIOS hits its minimum voltage threshold and forces a shutdown before the displayed percentage reaches zero. Run two to three full calibration cycles under moderate load so the fuel gauge IC maps the actual discharge curve of the new cell. After calibration, shutdown should not occur above 5% indicated charge.

Frequently Asked Questions

The HP ZBook shows 0% or "unknown battery" in Windows immediately after fitting the new cell — what causes this?

The fuel gauge IC on the ZBook's battery controller reads EEPROM data embedded in the cell to establish baseline capacity. On a brand-new replacement, that EEPROM data hasn't been validated against a real charge-discharge cycle yet, so Windows reports 0% or unknown until the IC completes its first full cycle. Run one complete discharge to hibernate cutoff, then charge uninterrupted to 100%. After that cycle the fuel gauge IC locks onto the new cell's curve and the percentage reads correctly.

Windows fuel gauge is jumping around — shows 60%, then 45%, then 70% within minutes on the new battery — is the cell faulty?

The ZBook's fuel gauge IC calibrates against discharge curves stored from the previous cell. A new Li-Polymer cell has a slightly different voltage-to-capacity curve, so the IC produces erratic readings until it collects enough data points from real cycles. This is not a cell fault. Run three full discharge-to-hibernate and charge-to-100% cycles under normal workstation load. By the third cycle the gauge IC has enough data to track the new cell accurately and the jumping stops.

System information shows the wrong Wh rating — BIOS says 83Wh but the replacement cell is 90.09Wh — should I be concerned?

The Wh value displayed in BIOS comes from the EEPROM register on the cell, which stores the rated design capacity. Until the BIOS battery learn cycle completes, it may display the old cell's stored value or a default table entry rather than the new cell's actual 90.09Wh rating. Complete one full discharge-to-hibernate followed by a full uninterrupted charge. After the learn cycle updates, open HP Support Assistant or check BIOS under Power and verify the Wh figure updates to match the new cell.
