It replaces OEM part numbers including HSTNN-C54C, RT06, RT09, and 530801-001, covering the dv3-2001tu, dv3-2001tx, dv3-2002tu, and over 197 additional dv3-2000 variants. The connector, pin count, and BMS handshake match HP's original spec for this platform.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003edv3-2000 platform fitment:\u003c\/strong\u003e\n    Every dv3-2000 variant in this family shares the same 10.8V three-cell architecture, connector pinout, and SMBus communication protocol — which is why one replacement cell covers the full range. The BMS on each unit reads the same register addresses regardless of sub-model suffix.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge and discharge cycles on a dv3-series unit and confirmed the BMS handshake initialised correctly, charge current stepped down at 95% as expected, and the protection circuit triggered cleanly at low-voltage cutoff without hard shutdown errors.\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 appears after every 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\"\u003eWhy the dv3-2000 BIOS reports poor battery health immediately after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe HP Pavilion dv3-2000 BIOS reads health data from EEPROM registers embedded in the original battery's fuel gauge IC. When a new cell is installed, those registers contain factory defaults — not learned cycle data — so the BIOS flags the battery as degraded or unknown. This is a data mismatch, not a fault with the replacement cell. Running one full discharge-to-hibernate followed by a complete uninterrupted charge gives the fuel gauge IC the data it needs to update those registers. After one or two cycles, the BIOS health indicator corrects itself.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003edv3-2000 shutting down at 20–30% charge shown on the gauge\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. The OS reads a percentage from stale register data, so the displayed figure and the real cell voltage diverge — the system hits the hardware low-voltage cutoff while the gauge still shows capacity remaining. It is not a defect in the replacement battery. Force a full discharge to hibernate-cutoff at least twice, charging fully between each cycle. After two calibration cycles, the gauge and the actual cell voltage align and shutdowns at false percentages stop.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43410812928090,"sku":"BWCS-HDV32NB-1","price":92.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43410812960858,"sku":"BWCS-HDV32NB-2","price":104.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43410812993626,"sku":"BWCS-HDV32NB-3","price":113.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HDV32NB-1.webp?v=1779581212","url":"https:\/\/batteryweb.com\/products\/hp-pavilion-dv3-2000-replacement-battery-108v-4400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
