It fits the full range of DV7 variants sharing the same connector and voltage rail. Cross-reference OEM part numbers 464059-121, 480385-001, HSTNN-IB74, HSTNN-DB74, and KS525AA before ordering.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eDV7 platform compatibility:\u003c\/strong\u003e\n    The DV7, DV7T, and DV7Z all run the same 14.4V battery rail with an identical connector pinout and BMS handshake protocol — that is why one cell covers all three sub-lines without any adapter or modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell on a DV7T under combined CPU and display load. The BMS held voltage above the cutoff threshold through full discharge cycles, and the charge controller accepted a full charge without interruption.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration on the DV7:\u003c\/strong\u003e\n    After fitting this cell, 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 on DV7 hardware.\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 fitting a new cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe HP DV7 BIOS reads health data stored in the battery's EEPROM. A new cell ships with factory EEPROM values that do not match the laptop's learned discharge profile from the old battery. The BIOS interprets that mismatch as degraded health and flags a warning. Running one complete discharge-to-hibernate cycle followed by an uninterrupted charge to 100% rewrites the learned cycle data and clears the warning on the next boot.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDV7 shutting down abruptly at 20–30% charge shown on screen\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a voltage cliff, not a fuel gauge error. Under full CPU plus display load, cell voltage drops steeply as capacity runs low — the BMS trips the cutoff before the OS gauge reaches 0%. The fuel gauge IC has not yet calibrated its discharge curve against the new cell's chemistry. After two or three full discharge-to-hibernate cycles, the IC maps the actual voltage curve and the shutdown moves down to the correct cutoff point near 3.0V per cell.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43410814730330,"sku":"BWCS-HDV7NB-1","price":112.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43410814763098,"sku":"BWCS-HDV7NB-2","price":128.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43410814795866,"sku":"BWCS-HDV7NB-3","price":140.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HDV7NB-1.webp?v=1779581212","url":"https:\/\/batteryweb.com\/products\/hp-pavilion-dv7-replacement-battery-144v-4400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
