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.

I'm writing this review to express my deep gratitude and appreciation for the quality of services provided to me by the BatteryWeb service team. I visited BatteryWeb to purchase a replacement battery for my Remington R9 razor. The staff was very responsive and I was really impressed with their willingness to help me and make the purchasing process as quick as possible. In particular I greatly appreciate the work of staff member Shane who was friendly and helpful.
In conclusion, I believe that BatteryWeb has excellent service staff who make their customers feel honored and valued.

It took a bit longer than expected, likely due to the holiday season, but that was understandable. So far, the battery seems to be working well!

Battery Care Tips

🔹 Getting Started

Charge your new battery fully before you use it for the first time. Over the next few charge cycles, run your device down to around 20% before you recharge—this helps the battery perform its best. After that, charge whenever you need to.

🔹 Keep It Healthy

Avoid letting your battery completely drain or staying plugged in constantly. Both extremes wear it out faster. Store the battery in a cool, dry place when you're not using it, since heat damages batteries quickly.

Delivery and Shipping

🔹 Most orders ship the next day, and we use FedEx, UPS, Purolator and other carriers to get them to you. Lithium batteries have to ship by ground only, not air or USPS. Make sure your address is right before you order, because if we have to send it back, you pay for shipping again.

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.

Frequently Asked Questions

My HP Spectre 13 battery shows 0% and won't charge at all after I put the new cell in — what's wrong?

The BMS handshake didn't complete on the first boot. Shut the laptop down fully, disconnect any power adapter, hold the power button for 15 seconds to drain residual rail voltage, then reconnect the charger before powering on. This forces the BIOS to re-initialise the battery controller and begin the charge cycle from a clean state. If it still reads 0%, check that the battery connector is fully seated — a partial connection on the Spectre 13's low-profile socket is enough to break the BMS signal.

The Spectre 13 stops charging at 80% and won't go higher — is the replacement cell faulty?

This is a BIOS-controlled charge limit, not a cell fault. HP ships many Spectre 13 units with Battery Care Manager active, which caps charging at 80% to reduce long-term cell stress. Open HP Support Assistant, go to Battery settings, and toggle the charge limit off. The battery will then charge to 100% on the next cycle.

Windows is showing the wrong Wh rating for this battery — it says 36Wh but the cell is rated 40.04Wh. Should I be concerned?

The Wh figure Windows displays is pulled from the EEPROM on the BMS chip, which stores the factory design capacity rather than the actual chemistry value of the fitted cell. After the first full calibration cycle — one full discharge to hibernate cutoff, then a complete charge to 100% — Windows Energy Report will update the full-charge capacity figure. The 40.04Wh rating in the product data reflects the cell's actual chemistry; run the calibration cycle and recheck the value in powercfg /batteryreport.
