It replaces OEM part numbers including 464059-121, HSTNN-IB74, HSTNN-DB75, and 480385-001 among others. Slide it into the same bay as the original — the connector and latch positions are identical across the DV7 range covered here.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eDV7 series compatibility:\u003c\/strong\u003e\n    The DV7, DV7T, DV7Z, and DV7T-1000 share the same 14.4V battery rail, connector pinout, and BMS handshake protocol — which is why one part number covers all of them. Swapping between these sub-models does not require any firmware or hardware change.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through full charge and discharge on a DV7 chassis. The BMS communicated correctly with the HP EC firmware, reported charge state without fault codes, and held voltage steady under combined CPU and display load without triggering a protection cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration on the DV7:\u003c\/strong\u003e\n    After fitting this battery, run one full discharge until the laptop hibernates, then charge uninterrupted to 100% without interruption. This resets the BIOS battery learn cycle and clears the inaccurate health warning that shows up after every cell swap on the Pavilion DV7 line.\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 Pavilion DV7 BIOS reads health data from an EEPROM register that was written by the original factory cell. When a replacement cell arrives, that register does not match the new chemistry data, and the BIOS flags it as degraded. This is a data mismatch, not a cell defect. Running one full discharge-to-hibernate followed by an uninterrupted charge to 100% rewrites the learn cycle and clears the warning. After two or three full cycles the fuel gauge IC re-calibrates and the health readout stabilises.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shuts down at 20–30% charge shown on screen\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the cell voltage drops below the BMS cutoff threshold under full load — CPU boost plus backlit display draws more current than the fuel gauge IC predicts from a poorly calibrated state-of-charge curve. The percentage shown is based on a stale calibration map, so the real cell voltage hits the cliff before the display reads zero. To fix it, let the laptop discharge fully to hibernate-cutoff at least twice in a row, then charge to 100% each time. After those two cycles the fuel gauge re-maps the voltage curve against the new cell and the shutdown point moves back to below 5%.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43410817581146,"sku":"BWCS-HDV7HB-1","price":133.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43410817613914,"sku":"BWCS-HDV7HB-2","price":153.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43410817646682,"sku":"BWCS-HDV7HB-3","price":169.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HDV7HB-1.webp?v=1779581212","url":"https:\/\/batteryweb.com\/products\/hp-pavilion-dv7-replacement-battery-144v-6600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
