It fits the VICTUS 16-d0009ua, VICTUS 15-FA0021NS, OMEN 16-N0066AX, OMEN 16-b1001nw, and over 229 additional models. OEM part numbers include WK04XL, HSTNN-IB9V, HSTNN-OB2C, and M38822-171.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eVICTUS 16 and OMEN 16 platform fit:\u003c\/strong\u003e\n    These models share a common 15.4V four-cell Li-Polymer architecture, identical connector pinout, and the same BMS handshake protocol — which is why one part number spans both product lines across multiple regional SKUs.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge-discharge cycles on VICTUS 16 hardware. The BMS negotiated correctly, charge termination triggered at full capacity, and no overcurrent fault codes appeared during high-draw GPU stress testing.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration on VICTUS 16:\u003c\/strong\u003e\n    After fitting this battery, run one full discharge down to hibernate-cutoff, then charge uninterrupted to 100%. This forces the BIOS battery learn cycle to reset against the new cell and clears the inaccurate \"poor health\" or \"unknown battery\" warning that routinely appears after any cell swap on this platform.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the VICTUS 16 BIOS reports poor health immediately after a battery swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe HP VICTUS 16 stores battery health data in EEPROM on the original cell. When a new cell is installed, the BIOS reads stale EEPROM values that don't match the new chemistry and flags the battery as degraded or unknown. This is a data mismatch, not a fault with the replacement cell. Running a full discharge-to-hibernate followed by an uninterrupted charge to 100% triggers the BIOS learn cycle and overwrites the stale EEPROM reference. After one or two completed cycles, HP Battery Check and Windows battery report should reflect accurate health status.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eVICTUS 16 shutting down at 20–30% charge shown on screen\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis shutdown pattern happens when the fuel gauge IC still holds calibration data from the old, degraded cell. Under combined CPU and display load, the new cell's actual voltage curve doesn't match the IC's stored model, so the laptop cuts power before the true low-voltage threshold. It is not a fault in the replacement cell. Run two full discharge-to-hibernate and uninterrupted-charge-to-100% cycles to recalibrate the fuel gauge IC against the new cell's actual capacity. After calibration, the cutoff should track correctly to the cell's real low-voltage floor near 12.0V.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409552703578,"sku":"BWCS-HPV160NB-1","price":88.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409552736346,"sku":"BWCS-HPV160NB-2","price":104.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409552769114,"sku":"BWCS-HPV160NB-3","price":115.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HPV160NB-1.webp?v=1779580013","url":"https:\/\/batteryweb.com\/products\/hp-victus-16-d0009ua-replacement-battery-154v-4500mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
