It replaces the original cell when the factory pack no longer holds a usable charge or fails to power the system under load. Voltage and connector match the original specification exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eNP6175 \/ NP6165 \/ NP3265 platform fit:\u003c\/strong\u003e\n    These Sager notebooks share the same battery bay dimensions, 11.1V three-cell voltage rail, and BMS handshake protocol. A single cell works across all listed models because the charge controller reads the same authentication data from the pack.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell on an NP-series board and confirmed the BMS accepted the pack, charge current stepped correctly through CC and CV phases, and the protection circuit tripped cleanly at low-voltage cutoff without triggering a hard fault.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install discharge cycle on the NP6175:\u003c\/strong\u003e\n    After fitting, run the battery down until the laptop hibernates, then charge uninterrupted to 100% without interruption. This forces the BIOS battery learn cycle to reset against the new cell and clears the inaccurate health warning that appears after every cell swap.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shutting down at 20–30% remaining after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens because the fuel gauge IC is still calibrated to the old cell's discharge curve. The new cell hits a voltage cliff under combined CPU and display load before the state-of-charge counter reaches zero. The system interprets the voltage drop as empty and shuts down even though the gauge shows charge remaining. Run two full discharge-to-hibernate cycles back-to-back, and the fuel gauge IC recalibrates its curve to the new cell's actual chemistry.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBIOS reporting battery health as \"poor\" or \"replace now\" after fitting a new cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe BIOS reads health data from EEPROM fields written by the original factory pack. A new cell ships with fresh EEPROM values that don't match the degraded baseline the BIOS stored from the old battery, so it flags a mismatch as poor health. This is a firmware read error, not a defect in the new cell. Complete one full learn cycle — discharge to hibernate cutoff, then charge to 100% uninterrupted — and the BIOS will overwrite the stored baseline with values from the new pack.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409818517594,"sku":"BWCS-CLM450NB-1","price":104.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409818550362,"sku":"BWCS-CLM450NB-2","price":118.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409818583130,"sku":"BWCS-CLM450NB-3","price":129.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CLM450NB-1.webp?v=1779581092","url":"https:\/\/batteryweb.com\/products\/sager-np6175-replacement-battery-111v-4400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
