Battery Care Tips
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
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 Book Pro 16 / OmniBook Ultra 14 — 7.72V Li-Polymer Replacement Battery (HSTNN-WB0F)
This is a 7.72V, 8300mAh (64.08Wh) lithium-polymer battery for the HP Book Pro 16, OmniBook Ultra 14, Pavilion Plus 14 Ryzen 7, and Envy x360 2-in-1 16-ad0097nr, among 200+ additional models sharing the WE04XL cell platform. It replaces OEM part HSTNN-WB0F and its cross-reference numbers. Install it when the original cell no longer holds a charge or the system shuts down unexpectedly under load.
- WE04XL platform compatibility: The Book Pro 16, OmniBook Ultra 14, and Envy x360 2-in-1 16 series share the same 7.72V two-cell Li-Polymer architecture, connector pinout, and BMS handshake protocol. That is why a single OEM part number — HSTNN-WB0F — covers all of them. The BIOS reads cell chemistry and rated Wh from the EEPROM on the battery PCB, so the replacement reports correctly to the firmware on first boot.
- Bench tested on actual hardware: We ran the battery through charge and discharge cycles on the Book Pro 16 platform. The BMS engaged thermal protection correctly, the BIOS recognised the cell without a firmware alert, and charge termination triggered cleanly at 100% with no overcharge event.
- Post-install calibration cycle: After fitting this cell, run one full discharge down to hibernate cutoff — do not interrupt it — then charge uninterrupted to 100%. This forces the fuel gauge IC to recalibrate against the new cell's actual capacity curve and clears the inaccurate health warning that appears in HP Support Assistant after every cell swap.
Why the Book Pro 16 shuts down at 20–30% after a battery swap
The fuel gauge IC on this platform maps percentage to voltage using data it built up against the old, degraded cell. After a swap, that map is wrong — the new cell's voltage cliff sits at a different point than the IC expects. When CPU and display load spike together, the cell voltage drops faster than the stale map predicts, and the system interprets it as a critical low-battery event. Running the calibration cycle described above forces the IC to rebuild its voltage-to-percentage table against the new cell's actual chemistry. After one complete discharge-to-hibernate and full uninterrupted recharge, the shutdowns stop.
BIOS reporting wrong Wh rating after installing HSTNN-WB0F
The BIOS reads watt-hour rating from the EEPROM on the battery's PCB, not by measuring the cell directly. If the figure shown in HP Support Assistant or the BIOS battery screen differs slightly from 64.08Wh, the EEPROM value on the replacement PCB is using a rounding convention from a different OEM batch — this does not affect charge behaviour or capacity. The cell still delivers the rated 8300mAh. To confirm actual capacity, let the system complete one full calibration cycle and check the "Full Charge Capacity" figure in Windows Battery Report (run powercfg /batteryreport from an elevated command prompt).

Frequently Asked Questions
HP Support Assistant is showing my new battery as "poor health" straight out of the box — is the cell faulty?
It is not faulty. The BIOS carries EEPROM health data from the old, degraded cell and applies it to whatever cell is installed next. Run one full discharge to hibernate cutoff, then charge uninterrupted to 100% — this triggers the BIOS battery learn cycle and rewrites the health register against the new cell. After that single cycle, Support Assistant will read the health correctly.
My Book Pro 16 fuel gauge is jumping around — showing 60%, then 45%, then back to 55% within minutes of unplugging
The fuel gauge IC calibrates itself against real charge and discharge data from the cell it is tracking. After a cell swap, it has no valid data for the new chemistry, so its estimates are unstable. Run two full discharge-to-hibernate and full recharge cycles without interruption. By the end of the second cycle, the IC has enough voltage curve data to report accurately — expect the gauge to settle within ±3%.
The laptop charges fine but Windows Battery Report shows Full Charge Capacity well below 64Wh on a brand-new cell
Battery Report reads the fuel gauge IC's current estimate, which is uncalibrated on a fresh install and will under-report. Run powercfg /batteryreport again after completing one full discharge-to-hibernate followed by an uninterrupted charge to 100%. The IC recalculates Full Charge Capacity at the end of that cycle, and the figure in the next report will reflect the cell's actual 8300mAh rating.
