About this replacement
HP Pavilion X2 12 — 7.6V Li-Polymer Replacement Battery (GI02XL)
This is a 7.6V Li-Polymer battery rated at 4350mAh (33.06Wh), replacing part number GI02XL. It fits the HP Pavilion X2 12 detachable 2-in-1, including the 12-B010N, 12-B096MS, and 12-B000 series. Cross-reference OEM part numbers HSTNN-LB7D, 832489-421, 833657-005, TPN-Q169, and 841565-001 before ordering.
- Pavilion X2 12 series fit: These models share the same flat Li-Polymer cell format, 7.6V rail, and BMS handshake protocol tied to the GI02XL part family. The tablet keyboard dock draws power from the same cell stack, so voltage tolerance across the BMS must match exactly.
- Bench tested on actual hardware: We cycled this cell on the Pavilion X2 12 platform and confirmed the BMS completed charge termination cleanly at full capacity. The system recognised the battery without throwing an unknown device flag during initial POST.
- First-cycle calibration on the Pavilion X2 12: After fitting, run one full discharge to hibernate cutoff, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears after every cell swap on this platform.
Why the Pavilion X2 12 shuts down at 20–30% after a battery swap
The BIOS fuel gauge IC retains learned discharge curves from the old cell. When the new cell's actual voltage profile doesn't match that stored curve, the system misreads remaining capacity and triggers an early shutdown. This happens under combined CPU and display load, where voltage sag on the new cell drops faster than the stale curve predicts. Two to three full discharge-charge cycles recalibrate the fuel gauge IC against the new cell's actual behaviour.
BIOS reporting battery health as "poor" or "unknown" immediately after fitting
The Pavilion X2 12 reads health data from the EEPROM embedded in the battery's protection circuit. A new cell ships with factory EEPROM values that haven't been validated against the BIOS's expected charge history — so the system flags it as degraded or unknown. This is a data mismatch, not a faulty cell. Run the battery learn cycle: discharge fully to hibernate, charge uninterrupted to 100%, then check HP Support Assistant — the health status should resolve to normal by the second full cycle.
