About this replacement
HP Chromebook 11 G8 EE — 7.7V Li-Polymer Replacement Battery (GH02XL)
This 7.7V, 5900mAh (45.43Wh) Li-Polymer battery replaces the original cell in the HP Chromebook 11 G8 EE and Chromebook 11 MK G9 EE. It also fits the Chromebook 14 G6 and a wide range of other HP education-series models sharing the same battery connector and BMS profile. OEM part numbers covered include GH02XL, HSTNN-DB9M, L75253-1C1, and L75253-271, among others.
- Education-series compatibility: The 11 G8 EE, 11 MK G9 EE, and 14 G6 share a 7.7V two-cell pack configuration with a common SMBus connector and BMS handshake. The replacement cell uses the same EEPROM data structure, so ChromeOS reads the pack without throwing an unknown-device error on first boot.
- Bench tested on actual hardware: We ran this pack on an 11 G8 EE chassis through charge and discharge cycles. The BMS engaged protection at the correct low-voltage cutoff and the fuel gauge IC synced within two full cycles. No thermal events or charge-stop anomalies were recorded.
- Post-install calibration tip: After fitting this cell, let the Chromebook run down to hibernate cutoff, then charge uninterrupted to 100% without using the device. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears after most cell swaps on this platform.
Why the Chromebook 11 G8 EE shuts down at 20–30% after a battery swap
The fuel gauge IC in this platform calibrates against the original cell's charge curve. A new cell has a slightly different voltage-to-capacity slope, so the IC miscalculates the remaining charge. Under full CPU and display load, the pack voltage drops faster than the IC predicts, and the laptop shuts off before the gauge reaches zero. This is not a fault with the replacement cell — it is a calibration gap. Run two full discharge-to-hibernate and charge-to-100% cycles without interruption, and the IC re-maps its curve against the new cell. Most users see accurate shutdowns after the second full cycle.
ChromeOS reporting battery health as "Poor" or Wh rating as incorrect after install
ChromeOS reads battery health and rated Wh from EEPROM data stored on the battery's fuel gauge chip. When the old cell's EEPROM data does not match the new cell's actual chemistry, the OS displays a mismatch — often showing a lower Wh figure or a poor health flag. This is an EEPROM reporting difference, not a physical defect. Navigate to chrome://system in the browser, locate the battery section, and confirm voltage is reading above 7.5V at rest. After one full learn cycle, the reported values align to the replacement cell's actual rated capacity.
