It covers OEM part numbers including HSTNN-YB4D, VK04, and 694864-851. Fit also extends to TPN-Q113 and TPN-Q114 board variants.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePavilion 14 and Sleekbook 14 compatibility:\u003c\/strong\u003e\n    Both lines share the same 14.4V battery rail, VK04 connector pinout, and BMS handshake protocol. A single cell works across the full variant range without adapter or firmware change.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell on a Pavilion 14 board and confirmed full BMS handshake, stable charge acceptance to 100%, and correct Wh reporting in HP Support Assistant. No error flags during the charge cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install recalibration on the Pavilion 14:\u003c\/strong\u003e\n    After installing, run one full discharge to hibernate-cutoff, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears 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\"\u003eBIOS reporting poor battery health immediately after replacing the cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eHP's BIOS reads health data from the battery's EEPROM, which still carries the degraded profile of the old cell at the moment of swap. The new cell's EEPROM hasn't been written with charge history yet, so the BIOS flags it as unknown or poor. Running one full discharge-to-hibernate then a full uninterrupted charge completes the battery learn cycle. After that cycle, HP Support Assistant and the BIOS should both report the cell correctly.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePavilion 14 shutting down at 20–30% charge shown on screen\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the fuel gauge IC hasn't yet calibrated against the new cell's actual voltage curve. Under full CPU and display load, the cell hits a voltage cliff that the uncalibrated gauge misreads as 20–30% remaining. The system interprets the voltage drop as a critical low and cuts power. Run two or three full discharge-to-hibernate and full-charge cycles — the gauge IC maps the new curve and the shutdowns stop. After calibration, verify the cell holds above 12.0V under load before the shutdown threshold triggers.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409803870298,"sku":"BWCS-HPV140NB-1","price":95.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409803903066,"sku":"BWCS-HPV140NB-2","price":109.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409803935834,"sku":"BWCS-HPV140NB-3","price":118.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HPV140NB-1.webp?v=1779580992","url":"https:\/\/batteryweb.com\/products\/hp-pavilion-14-replacement-battery-144v-2450mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
