It replaces degraded or failed cells in laptops that no longer hold charge or shut down unexpectedly. It fits the dv3-2000 series under OEM part numbers including HSTNN-C54C, RT09, RT06, and 530801-001, among others.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003edv3-2000 series fit:\u003c\/strong\u003e\n    These models share the same 10.8V battery rail, physical connector, and BMS handshake protocol. The same cell block spans dv3-2001tu, dv3-2001tx, dv3-2002tu, and the wider dv3 series, which is why a single OEM part number covers nearly 200 variants.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this battery through full charge and discharge on a dv3-series unit, confirmed BMS communication, and verified charge acceptance across all six cells. Voltage at full charge held at 12.4V with no cell imbalance flagged.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration on the dv3-2000:\u003c\/strong\u003e\n    After fitting, run one full discharge down to hibernate cutoff, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning that nearly always appears after a 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\"\u003eBIOS reporting poor battery health immediately after fitting a new cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe HP dv3 BIOS reads health data stored in the battery's EEPROM, not from live cell measurement. When a new battery arrives, its EEPROM may carry rated-condition data that does not match the laptop's charge history, triggering a false \"battery health poor\" or \"consider replacing battery\" alert. This is a firmware calibration gap, not a fault with the cell. Run a full discharge-to-hibernate followed by an uninterrupted full charge — the BIOS learn cycle rewrites its reference data against the new cell and the warning clears.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shuts down at 20–30% with no warning after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the fuel gauge IC has not yet calibrated against the new cell's actual voltage curve. The dv3's fuel gauge maps percentage to voltage based on data from the old, degraded cell, so it underestimates how quickly the new cell drops under full CPU and display load. The result is a sudden voltage cliff the system wasn't expecting, triggering an immediate shutdown. Run two to three full discharge-and-charge cycles — after that, the fuel gauge recalibrates and reported percentage aligns with actual remaining capacity.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409819074650,"sku":"BWCS-HDV32HB-1","price":125.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409819107418,"sku":"BWCS-HDV32HB-2","price":145.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409819140186,"sku":"BWCS-HDV32HB-3","price":158.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HDV32HB-1.webp?v=1779581113","url":"https:\/\/batteryweb.com\/products\/hp-pavilion-dv3-2000-replacement-battery-108v-6600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
