About this replacement
HP Chromebook X360 11 — 7.7V Li-Polymer Replacement Battery (GB02XL)
This is a 7.7V, 5900mAh (45.43Wh) Li-Polymer battery for the HP Chromebook X360 11 convertible laptop. It fits the 2-in-1 hinge models that rotate between laptop and tablet mode. OEM part numbers GB02XL, L42550-2C1, L42583-005, HSTNN-DB7X, and HSTNN-IB8W all cross-reference to this cell.
- Chromebook X360 11 fit group: All models in this line share the same 7.7V two-cell Li-Polymer pack, the same flat flex connector, and the same BMS communication protocol over SMBus. The connector orientation and board-side latch are consistent across the 14-DB0023DX and related SKUs listed above.
- Bench tested on actual hardware: We ran this cell through charge, discharge, and BMS handshake verification on the X360 11 platform. The BMS recognised the cell, reported state-of-charge correctly after two calibration cycles, and held charge limit thresholds without tripping fault flags.
- First-cycle calibration on ChromeOS: After installation, run the device down until it hibernates on its own, then charge uninterrupted to 100% without using the device. This lets the fuel gauge IC re-learn the cell's actual capacity boundaries and clears the inaccurate health warning ChromeOS displays after every cell swap.
Why the X360 11 shuts down at 20–30% after a battery swap
The fuel gauge IC stores a capacity map built against the old cell's voltage curve. When you install a new cell, that map is stale. Under combined CPU and display load, the firmware sees the voltage drop faster than the old curve predicted and triggers an emergency shutdown — even though the cell still has usable charge. This is not a battery fault. Two full discharge-to-hibernate and uninterrupted charge cycles overwrite the old map and stop the false cutoffs.
ChromeOS reporting battery health as "poor" or Wh rating as wrong after replacement
The system reads battery health and rated Wh from EEPROM data embedded in the original cell's BMS. A replacement cell carries its own EEPROM values, which may differ slightly from HP's factory figures — ChromeOS flags this as a health warning or shows an unexpected Wh number in Settings. The warning is a data mismatch, not a sign the cell is faulty. Complete the full learn cycle described in the care tip above and the health indicator will update to reflect the new cell's actual state.
