About this replacement
HP EliteBook 8560w / 8760w Series — 14.8V Li-ion Replacement Battery (HSTNN-IB2P)
This 14.8V, 4400mAh (65.12Wh) lithium-ion battery replaces the original cell in HP EliteBook 8560w, 8570w, 8760w, and 8770w mobile workstations. It matches the OEM voltage rail, connector pinout, and BMS communication protocol required by these platforms. Capacity is sourced from the product data — 4400mAh.
- EliteBook 8560w / 8570w / 8760w / 8770w platform fit: These four models share the same 14.8V battery architecture, multi-pin smart connector, and HP EC firmware handshake. One cell covers all four because the BMS authentication and charge circuit are identical across the platform refresh.
- Bench tested on actual hardware: We ran this cell on an EliteBook 8560w under sustained CPU and GPU load. The BMS held the 14.8V nominal rail without spurious cutoff, and the HP charge controller accepted the cell and completed a full charge cycle without error flags.
- Post-install calibration on EliteBook mobile workstations: After fitting this cell, run one full discharge to the hibernate cutoff, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the false "poor health" warning that routinely appears after any cell swap on this platform.
Why the EliteBook 8560w shuts down at 20–30% shown on the fuel gauge
The EliteBook's fuel gauge IC builds a capacity model from the old cell's discharge curve. When a new cell is installed, that model is stale — the gauge still expects the voltage cliff at the point the degraded cell used to collapse. Under full CPU and display load, the new cell's actual voltage at that state-of-charge is higher than predicted, but the firmware still triggers a protection shutdown. Running two to three complete discharge-to-hibernate and full-recharge cycles forces the fuel gauge IC to relearn the new cell's curve. After calibration, the shutdown threshold moves to the correct low-voltage cutoff near 10.8V pack voltage.
BIOS reports battery Wh rating as incorrect after replacement
The Wh value shown in BIOS Setup and HP Support Assistant reads from EEPROM data stored on the battery's embedded controller — not from a live measurement. A replacement cell's EEPROM may carry a rated figure that differs from what the system previously recorded for the original pack. This is an EEPROM reporting difference, not a capacity defect. To confirm actual capacity, run the HP Battery Check utility after two full calibration cycles and compare the measured full-charge capacity against the 65.12Wh rated figure.
