It fits the dv3-1000, dv3-1001TX, dv3-1051xx, dv3-1073cl, and additional dv3 variants sharing the same bay and connector. OEM part numbers covered include 500028-142, 500029-142, HSTNN-IB82, HSTNN-IB83, and NB801AA.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003edv3-1000 series compatibility:\u003c\/strong\u003e\n    These dv3 models share the same 10.8V three-cell-series architecture, identical connector pinout, and a common BMS handshake protocol. One replacement cell covers all listed variants without 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 dv3-1001TX through full charge and discharge cycles. The BMS communicated correctly with the BIOS, charge termination triggered cleanly at 100%, and no protection-circuit trips occurred during load testing.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration on the dv3:\u003c\/strong\u003e\n    After fitting, run one full discharge to hibernate-cutoff, then charge uninterrupted to 100% without interruption. This resets the BIOS battery learn cycle and clears the false \"poor health\" warning that appears in HP Support Assistant after a 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 dv3-1000 shuts down at 20–30% charge remaining\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe dv3 BIOS uses fuel gauge data from the battery's EEPROM to predict shutdown voltage. With a new cell, that EEPROM data hasn't been calibrated yet, so the fuel gauge IC miscalculates remaining capacity. Under combined CPU and display load, the cell hits a voltage cliff faster than the gauge predicts, and the BIOS forces an emergency shutdown. Running two or three full discharge-to-hibernate cycles calibrates the fuel gauge IC against the new cell's actual voltage curve and stops the premature cutoffs.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBIOS reporting incorrect Wh rating after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eWhen you swap cells, the BIOS reads the Wh rating stored in the battery's EEPROM — not the actual chemistry. If the EEPROM value doesn't match the new cell's rated capacity, HP Support Assistant and Windows battery reports will show a mismatched Wh figure. This is an EEPROM metadata difference, not a fault with the replacement cell. Confirm actual capacity is correct at 71.28Wh by checking the cell label directly, then allow two full charge cycles for the fuel gauge IC to update its readings.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43410809913434,"sku":"BWCS-HDV3HB-1","price":121.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43410809946202,"sku":"BWCS-HDV3HB-2","price":139.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43410809978970,"sku":"BWCS-HDV3HB-3","price":152.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HDV3HB-1.webp?v=1779581157","url":"https:\/\/batteryweb.com\/products\/hp-pavilion-dv3-1000-replacement-battery-108v-6600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
