About this replacement
HP EliteBook X360 830 G6 — 7.7V Li-Polymer Replacement Battery (OR04XL)
This is a 7.7V, 6400mAh (49.28Wh) Li-Polymer replacement battery for the HP EliteBook X360 830 G6 convertible laptop. It fits the 2-in-1 form factor and matches the original cell's voltage rail, capacity, and BMS communication protocol. OEM part numbers OR04XL, HSTNN-IB8U, HSTNN-DB9C, L34209-1C1, L34209-1B1, and L34209-2B1 all cross-reference to this unit.
- EliteBook X360 830 G6 fit: The G6 830 uses a flat Li-Polymer pack locked to a 7.7V charging rail with a dedicated BMS handshake over SMBus. The connector pinout and physical dimensions (283.60 × 89.70 × 5.50mm) match the OEM bay exactly — no modification needed.
- Bench tested on actual hardware: We ran this cell through full charge and discharge cycles on the X360 830 G6 platform. The BMS negotiated correctly over SMBus, charge termination triggered at 100%, and no fault codes were thrown during the test sequence.
- Post-install calibration on the X360 830 G6: After fitting this cell, 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 in HP Support Assistant after every cell swap.
BIOS reporting battery health as poor after fitting the OR04XL
The HP EliteBook BIOS reads health data stored in the battery's EEPROM and compares it against charge history from the old cell. A new cell has zero cycle count and fresh EEPROM data, which the BIOS initially flags as inconsistent. This is a firmware calibration issue, not a battery fault. Run one full discharge-to-hibernate cycle followed by an uninterrupted charge to 100% — this lets the BIOS battery learn cycle write new baseline data to the fuel gauge IC and clear the warning.
EliteBook X360 830 G6 shutting down at 20–30% charge shown
This happens when the fuel gauge IC has not yet calibrated against the new cell's actual voltage curve. The displayed percentage does not match the real state of charge, so the system hits the low-voltage cutoff before the gauge reaches 0%. The fix is completing two or three full discharge-to-hibernate cycles without interruption. After calibration, the gauge and actual cell voltage align — the shutdown point drops back to below 5% as expected.
