About this replacement
HP Omen X 17 Series — 11.55V Li-Polymer Replacement Battery (DG06XL / 925149-855)
This 11.55V, 8100mAh (93.56Wh) Li-Polymer battery replaces the original DG06XL cell in the HP Omen X 17 gaming laptop lineup. It fits the 17-AP016TX, 17-ap045tx, 17-ap000ng, 17-AP027TX, and over 110 additional Omen X 17 variants sharing the same OEM part numbers 925149-855, 925197-271, DG06099XL, and HSTNN-DB8G. Capacity figures are taken directly from the product data — 8100mAh matched to the original cell specification.
- Omen X 17 AP-series compatibility: Every AP-series variant in this lineup runs the same 11.55V three-cell Li-Polymer architecture, uses the same physical connector, and communicates with the EC via the same SMBus BMS handshake — which is why one cell covers the full model range.
- Bench tested on actual hardware: We ran this cell on an Omen X 17 AP-series board. The BMS handshake completed without fault codes, the EC accepted the EEPROM data, and the charge controller stepped through pre-charge, CC, and CV phases cleanly to full capacity.
- Post-install calibration on the Omen X 17: After fitting this cell, run one full discharge to hibernate-cutoff — let the laptop shut itself down, not a manual power-off — then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning the EC throws after any cell swap.
BIOS reporting poor battery health immediately after replacement
The Omen X 17 EC reads EEPROM data stored on the outgoing cell and flags a mismatch when a new cell is installed — this is expected behaviour, not a fault with the replacement. The EC needs to run a full learn cycle against the new cell before it updates its health model. Until that cycle completes, Windows Battery Report and HP Support Assistant will both show warnings that have no bearing on actual cell condition. One full discharge-to-hibernate followed by an uninterrupted charge to 100% clears the flag in most cases.
Omen X 17 shutting down abruptly at 20–30% shown on the fuel gauge
This is a voltage cliff — under full CPU and GPU load combined with the display backlight, the cell voltage drops faster than the fuel gauge IC can track, and the EC triggers a hard shutdown before the displayed percentage reaches zero. It does not mean the battery is faulty; it means the fuel gauge IC has not yet calibrated its discharge curve against the new cell's chemistry. Run two or three full discharge-to-recharge cycles without interruption. After calibration, the EC and fuel gauge IC align, and the shutdown threshold moves to the correct low-voltage cutoff near 10.2V.
