About this replacement
HP ZBook 17 G3 — 11.4V Li-ion Replacement Battery (AI06XL)
This is an 11.4V, 8300mAh (94.62Wh) Li-ion battery for the HP ZBook 17 G3 mobile workstation. It replaces OEM part numbers AI06XL, 808397-421, HSTNN-LB6X, and 808451-001 among others. Fits the full ZBook 17 G3 lineup including V1Q04UT, V1Q08UT, and T7V62ET variants.
- ZBook 17 G3 platform fit: Every ZBook 17 G3 variant in this range uses the same six-cell 11.4V battery bay, the same connector pinout, and the same BMS handshake protocol — so one cell covers all 29+ sub-models without modification.
- Bench tested on actual hardware: We ran this cell through charge and discharge cycles on a ZBook 17 G3 unit. The BMS negotiated correctly, charge termination triggered at full capacity, and no over-voltage faults were logged during the test.
- First-cycle conditioning on the ZBook 17 G3: After installing, run one full discharge down to hibernate cutoff, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning that almost always appears after a cell swap on this platform.
BIOS reporting battery health as poor immediately after swapping the AI06XL cell
The ZBook 17 G3 BIOS reads health data stored in the old battery's EEPROM. When a new cell arrives, that EEPROM data doesn't match what the BIOS expects, so it flags the battery as degraded — even at 100% charge. This isn't a fault with the replacement cell. Run one complete discharge-to-hibernate followed by a full uninterrupted charge. The BIOS battery learn cycle rewrites the health baseline against the new cell and clears the warning.
ZBook 17 G3 shutting down without warning while showing 20–30% remaining
This is a voltage cliff issue. Under combined CPU, GPU, and display load — common during renders or CAD work — the cell voltage drops faster than the fuel gauge IC can track. The system hits the hardware cutoff voltage before the reported percentage reaches zero. The fuel gauge IC needs two or three full calibration cycles against the new cell to map the discharge curve accurately. Complete those cycles and the reported percentage at shutdown will track much closer to actual cell depletion — typically below 5%.
