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.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eWE04XL platform compatibility:\u003c\/strong\u003e\n    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.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    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.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration cycle:\u003c\/strong\u003e\n    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.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Book Pro 16 shuts down at 20–30% after a battery swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe 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.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBIOS reporting wrong Wh rating after installing HSTNN-WB0F\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe 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 \u003ccode\u003epowercfg \/batteryreport\u003c\/code\u003e from an elevated command prompt).\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409517674586,"sku":"BWCS-HPR147NB-1","price":81.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409517707354,"sku":"BWCS-HPR147NB-2","price":95.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409517740122,"sku":"BWCS-HPR147NB-3","price":106.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HPR147NB-1.webp?v=1779579851","url":"https:\/\/batteryweb.com\/products\/hp-book-pro-16-replacement-battery-772v-8300mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
