It fits models including the DV6190EU, DV6191EU, and DV6195EA, covering a wide spread of that generation. OEM part numbers HSTNN-DB31, HSTNN-IB31, HSTNN-W20C, and 417066-001 are all cross-compatible with this cell configuration.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eDV6000 platform compatibility:\u003c\/strong\u003e\n    These DV6190-series models share the same 10.8V battery rail, connector pinout, and BMS handshake protocol across the platform. That consistency means one cell swap covers a broad range of Pavilion DV6000-generation units without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this battery through charge and discharge cycles on DV6-class hardware and confirmed the BMS communicates correctly with the HP power controller — no false fault flags, no premature cutoff on a standard load profile.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle conditioning on HP Pavilion notebooks:\u003c\/strong\u003e\n    After fitting this battery, run the laptop on battery only until it hibernates at low charge, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears 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 DV6190 BIOS reports poor battery health after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe HP Pavilion DV6190 reads battery health using EEPROM data stored on the old cell — not from live measurements of the new one. When a fresh battery goes in, the BIOS compares the new cell's reported capacity against the degraded baseline it has cached, which triggers a false \"poor health\" or \"consider replacing\" warning. This clears after one or two full discharge-to-hibernate and uninterrupted charge cycles. The BIOS battery learn cycle rewrites that cached data to reflect the actual capacity of the replacement cell.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eFuel gauge reading wildly inaccurate for the first few charge cycles\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe DV6190's fuel gauge IC calibrates itself against the battery it has learned over time. Drop in a new cell and the IC is working from stale reference points, so percentage readings can jump, stall, or report 100% when the battery is nowhere near full. This is not a fault with the replacement battery — it is a calibration gap. Run two to three full discharge-to-hibernate and full-charge cycles and the fuel gauge IC will recalibrate against the new cell's actual charge curve. After the third cycle, percentage readings should stabilise to within a few points of actual capacity.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43410868404314,"sku":"BWCS-CV3000NB-1","price":65.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43410868437082,"sku":"BWCS-CV3000NB-2","price":75.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43410868469850,"sku":"BWCS-CV3000NB-3","price":83.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CV3000NB-1.webp?v=1779581402","url":"https:\/\/batteryweb.com\/products\/hp-pavillion-dv6190-replacement-battery-108v-4400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
