Why this battery

Fits HP Spectre 13-V115TU and replaces OEM part BF04XL, HSTNN-LB8C, 924843-42, BF04043XL, 924843-421, 924960-855, TPN-C132.
Voltage runs 7.7V at 5200mAh capacity, delivering 40.04Wh total — sufficient for full-day mobile work on this ultrabook.
Connector type is proprietary HP contact pad; seats flush into the battery slot with no locking tab.
We ran full charge cycles on the Spectre 13 platform — BMS accepted the cell without fault codes and held voltage under sustained CPU plus display load.
After installation, fully discharge to sleep-mode cutoff then charge without interruption to 100% — this resets the BIOS battery learn cycle and clears false health warnings.

About this replacement

HP Spectre 13-V115TU — 7.7V Li-Polymer Replacement Battery (BF04XL / HSTNN-LB8C)

This is a 7.7V, 5200mAh (40.04Wh) lithium-polymer cell for the HP Spectre 13-V115TU ultrabook and its Y8J11PA / Y8J13PA variants. It fits the same connector, BMS handshake, and voltage rail as OEM part BF04XL. Use the Capacity field — 5200mAh — as the source of truth, not third-party listings.

Spectre 13 V-series platform fit: The V115TU and V117TU share the TPN-C132 battery bay, identical connector pinout, and the same BMS communication protocol. One cell covers both variants without any wiring or firmware modification.
Bench tested on actual hardware: We ran this cell on the Spectre 13 platform and confirmed the BMS accepted the EEPROM handshake on first boot, reported voltage correctly, and began a charge cycle without triggering an unknown-battery fault.
Post-install calibration cycle: After fitting this cell, discharge the laptop to hibernate cutoff, then charge uninterrupted to 100% before unplugging. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears in HP Support Assistant after every cell swap.

Why the Spectre 13 shuts down at 20–30% remaining after a battery swap

The Spectre 13 runs a combined CPU and display load that pulls hard on the cell during peak tasks. A new cell with an uncalibrated fuel gauge IC cannot accurately map its voltage curve to the remaining capacity, so the BIOS triggers a low-voltage shutdown before the gauge catches up. The cell still has charge — the system just doesn't know it yet. Two full discharge-to-hibernate and full-recharge cycles recalibrate the IC and push the shutdown point back to the correct level.

BIOS reporting battery health as "Poor" or "Unknown" after replacement

HP's BIOS reads EEPROM data embedded in the battery's BMS chip to display health status. When a new cell arrives, the EEPROM reports zero charge cycles and factory defaults — values the BIOS interprets as a degraded or unrecognised unit. This is not a fault with the cell. Run one complete discharge-to-hibernate cycle followed by a full uninterrupted charge to 100%, then reboot and check HP Support Assistant — the health status will update once the learn cycle completes.
