It replaces OEM part numbers under the 6-87-N750S and N750BAT-4 family. Fit models confirmed include B1511(44587), B1511(44591), B1511(44461), and B1701(44697).\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eN750-platform coverage:\u003c\/strong\u003e\n    The B1511 and B1701 series share the same 14.4V four-cell Li-ion architecture, connector pinout, and BMS handshake protocol — which is why a single part number family covers multiple chassis codes across both models.\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 N75x-class hardware. The BMS communicated correctly with the host system, and the protection circuit responded as expected to overvoltage and cutoff thresholds.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap calibration on Clevo notebooks:\u003c\/strong\u003e\n    After fitting a new cell, run one full discharge to the hibernate-cutoff point, then charge uninterrupted to 100%. 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 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 B1511 BIOS reports poor health immediately after a battery swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe BIOS on Clevo N75x-based systems reads health data from EEPROM registers that were written by the original cell over its service life. A new cell arrives with fresh EEPROM values that don't match the accumulated charge history the BIOS expects. The system interprets that mismatch as a degraded or unknown battery. Running a full discharge-to-hibernate followed by an uninterrupted charge to 100% triggers the learn cycle and rewrites those registers against the new cell's actual chemistry.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shutting down at 20–30% shown on the gauge after battery replacement\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 voltage curve. The gauge is still using the old cell's discharge profile, so it misreads the knee of the voltage curve and trips a premature shutdown. Under combined CPU and display load, the cell voltage drops faster than the uncalibrated gauge predicts — the system sees what looks like an imminent cutoff and shuts down. Run two to three full discharge and charge cycles; the fuel gauge IC will track the actual voltage floor, which on this cell is 12.0V at cutoff.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409537663066,"sku":"BWCS-CLB151NB-1","price":81.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43409537695834,"sku":"BWCS-CLB151NB-2","price":95.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43409537728602,"sku":"BWCS-CLB151NB-3","price":106.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CLB151NB-1.webp?v=1779579964","url":"https:\/\/batteryweb.com\/products\/clevo-b151144587n751wu-replacement-battery-144v-2200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
