About this replacement
HP Chromebook 14-X / 14-Q Series — 11.1V Li-Polymer Replacement Battery (HSTNN-IB6P)
This 11.1V, 3100mAh (34.41Wh) lithium-polymer cell replaces the original battery in the HP Chromebook 14-X and 14-Q series. It fits a wide range of variants including the 14-X013DX and 14-X010NR, and crosses to OEM part numbers HSTNN-IB6P, BO03XL, 774159-001, and TPN-Q137 among others. If the original cell no longer holds charge or the laptop refuses to run off battery alone, this is the direct swap.
- 14-X and 14-Q shared battery platform: Both Chromebook lines use the same three-cell Li-Polymer pack at 11.1V nominal, the same connector orientation, and the same BMS handshake over the SMBus line to the EC. Swapping between 14-X and 14-Q variants works because the embedded controller uses the same charge profile for both.
- Bench tested on actual hardware: We ran this cell through charge and discharge cycles on a 14-X unit. The BMS communicated correctly with the EC from the first boot, charge termination triggered cleanly at full voltage, and no fault codes were logged in the battery status register.
- First-cycle calibration on the 14-X: After installing, run one full discharge until the Chromebook hibernates, then charge uninterrupted to 100% without interruption. This forces the fuel gauge IC to recalibrate against the new cell's actual capacity and clears the inaccurate health warning the EC throws after any cell swap.
Why the Chromebook 14-X shuts down at 20–30% after a battery swap
The EC on the 14-X uses stored discharge curves from the previous cell to predict the voltage cliff — the point where cell voltage drops sharply under combined CPU and display load. A new cell has a different curve, so the EC trips the low-voltage cutoff earlier than the percentage shown on screen. The gauge says 25%, but the cell is already at the knee of its discharge curve under load. Running two full calibration cycles resets these stored curves and brings the shutdown point back in line with the displayed percentage.
ChromeOS reporting battery health as "poor" or capacity as 0% after fitting a new cell
The EC reads battery health from EEPROM data that carries over from the old cell's cycle count and degradation history — it does not automatically recognise a new cell as healthy. ChromeOS flags the battery as poor or unknown because the EEPROM values no longer match the cell's actual state. Force a battery learn cycle: discharge fully to hibernate cutoff, then charge without interruption to 100%. After two full cycles the EC updates its stored data and the health status reports correctly. If the warning persists, check battery status in crosh using the command battery_test 1 and confirm voltage reads above 11.0V at rest.
