Up to 19% off
New arrival
From $100.99 USD $124.99
Shipping calculated at checkout.
Fits HP ENVY X360 13-BF0000CI and related models; replaces HSTNN-OB2Y, WF04XL, and TPN-IB0O battery part numbers.
7.7V 8200mAh Li-Polymer cell delivers 63.14Wh output for all-day convertible use between charging cycles.
Connector slides straight into the factory slot with no adapter needed; locking tab secures without forcing.
Bench testing shows the BMS accepts charge current immediately on first insertion; no conditioning cycle required.
After installation, run one full discharge to hibernation then charge uninterrupted to 100% — this resets the BIOS battery learn cycle and clears inaccurate health warnings that appear after cell replacement.

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 ENVY x360 13-BF Series — 7.7V Li-Polymer Replacement Battery (HSTNN-OB2Y)

This is a 7.7V 8200mAh (63.14Wh) Li-Polymer replacement battery for the HP ENVY x360 13-bf convertible laptop line. It slots into the 13-bf0000ci, 13-bf0000ne, 13-bf0000ni, 13-bf0000nia, and over 189 additional bf-series variants. Cross-reference OEM part numbers HSTNN-OB2Y, M89926-1D1, M89926-AC1, M90073-005, TPN-IB0O, or WF04XL before ordering.

  • 13-bf series platform fit: All 13-bf variants share the same 7.7V battery rail, physical connector pinout, and BMS handshake protocol. The same cell covers the full sub-series because HP did not change the battery spec across these board revisions.
  • Bench tested on actual hardware: We ran this cell on a 13-bf unit under combined CPU and display load. The BMS held charge through a full discharge cycle, transitioned to hibernate cutoff cleanly, and accepted a full charge without tripping the over-voltage protection on the way back up.
  • First-cycle calibration after install: After fitting this cell, discharge the laptop fully until it hibernates, then charge it to 100% without interruption. This forces the BIOS battery learn cycle to reset against the new cell's actual capacity and clears the inaccurate health warning that appears immediately after every cell swap.

Why the ENVY x360 13-bf shuts down at 20–30% after a battery swap

The fuel gauge IC in the 13-bf uses stored discharge curve data from the old cell to predict remaining capacity. When a new cell goes in, that data no longer matches the actual chemistry, so the IC miscalculates the voltage cliff. Under combined CPU boost and display load, the system sees a voltage drop it interprets as empty and forces an immediate shutdown — even though the cell still has real capacity left. Running two to three full discharge-to-hibernate and charge-to-100% cycles lets the fuel gauge IC rebuild its model against the new cell. After those cycles, the gauge tracks accurately and the early shutdowns stop.

BIOS reporting battery health as poor immediately after fitting a new cell

The BIOS reads health data from the battery's EEPROM, which is pre-populated at the factory with rated cycle count and Wh values. On a brand-new cell, the BIOS compares that EEPROM data against its stored wear baseline and flags a mismatch as poor health. This is a read-order issue, not a fault with the cell. Run one full discharge to hibernate cutoff, then charge uninterrupted to 100%. On the next boot, the BIOS battery learn cycle completes and the health status clears to normal.

Frequently Asked Questions

My HP ENVY x360 13-bf shows the new battery as 0% or "unknown" in Windows right after fitting it — what's happening?

The Windows fuel gauge IC is still reading EEPROM data calibrated to the old cell, so it has no valid reference point for the new one and reports 0% or unknown. This is not a wiring or compatibility fault. Charge the laptop to 100% uninterrupted, then let it discharge fully to hibernate. After one complete cycle, the fuel gauge IC re-maps its discharge curve against the new cell and the percentage reads correctly from that point forward.

The replacement cell shows 63Wh in my battery report but Windows energy report says something different — is the cell underspec?

The Wh figure Windows displays in the battery report is pulled from the EEPROM's rated design capacity, while the energy report calculates full-charge capacity from actual measured voltage. These two figures will not match until the fuel gauge IC has run at least one full calibration cycle. The cell in this listing is rated at 63.14Wh — that is the correct spec. Run one full discharge to hibernate, charge back to 100%, and re-check the energy report; the full-charge capacity figure will converge toward the design capacity rating.

The 13-bf stops charging at exactly 80% and won't go higher — is the new battery faulty?

This is almost always a BIOS-controlled charge limit, not a cell fault. HP ships the 13-bf with a battery health charging mode that caps charge at 80% to reduce long-term wear when the laptop is frequently plugged in. The cell itself accepts a full charge — the BIOS is blocking it. Go to HP Support Assistant or MyHP app, find Battery Settings or Battery Health Charging, and switch the mode to "Full Charge." The battery will then charge to 100% on the next cycle.
