About this replacement
HP Omen X 2S 15-DG0003NC — 11.55V Li-Polymer Replacement Battery (DX06XL)
This is an 11.55V, 5900mAh (68.15Wh) lithium-polymer battery for the HP Omen X 2S gaming laptop. It replaces OEM part DX06XL, also cross-referenced as HSTNN-DB98, L32701-2C1, and L32749-00. It fits the Omen X 2S 15-DG0003NC, 15-DG0075CL, 15-DG0019TX, 15-DG0001NC, and additional variants in the same line.
- Omen X 2S 15-DG series compatibility: These models share the same 11.55V three-cell battery rail, the same physical connector, and the same BMS communication protocol. One cell part number — DX06XL — covers the full DG0xxx range because HP used an identical power architecture across all Omen X 2S 15-inch configurations.
- Bench tested on actual hardware: We ran this cell on an Omen X 2S unit under combined CPU and GPU load. The BMS held steady at the 11.55V nominal rail, accepted a full charge cycle without triggering a protection cutoff, and communicated cell data correctly back to the system board.
- First-cycle calibration on the Omen X 2S: After fitting, run the laptop down to hibernate-cutoff on battery power, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle. Without it, the system pulls stale EEPROM data from the old cell and flags the new one as degraded.
BIOS reporting poor battery health immediately after swapping the DX06XL
When you replace the cell, the HP BIOS reads health data cached in the embedded controller — not live readings from the new cell. That cached EEPROM data reflects the worn-out battery you just removed. The health warning will persist until the BIOS completes a full learn cycle against the new cell's actual charge curve. Run one full discharge to hibernate-cutoff, then a continuous charge to 100%, and the health flag clears.
Omen X 2S shutting down abruptly at 20–30% shown on the fuel gauge
This happens when the fuel gauge IC has not yet calibrated against the new cell's voltage curve. The gauge still maps to the old cell's degraded profile, so it misreads the remaining capacity. Under a sudden load spike — GPU boost or CPU all-core — the actual cell voltage drops faster than the gauge expects, and the BMS triggers an emergency cutoff before the displayed percentage reaches zero. Two to three full discharge-and-charge cycles recalibrate the fuel gauge IC. After calibration, the cutoff point should align with readings below 5%.
