It slots in where the original cell has aged out or failed to hold charge. Physical dimensions are 136.27 × 72.20 × 20.09mm — measure your original before ordering if you are unsure.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMaster N100 \/ N150 \/ Premiun 2035 fit:\u003c\/strong\u003e\n    These three models share the same battery bay geometry, connector pinout, and BMS communication protocol, which is why a single cell covers all three. The voltage rail and cell count match the original spec on each platform.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge and discharge on the Master N100 and monitored BMS handshake, cutoff voltage, and charge acceptance. The protection circuit responded correctly at both the low-voltage floor and the high-voltage ceiling.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle recalibration on the Master N100:\u003c\/strong\u003e\n    After installation, run the laptop on battery alone until it reaches hibernate cutoff, then charge uninterrupted to 100% without unplugging. This forces the BIOS battery-learn cycle to reset against the new cell and clears the false health warning that almost always 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\"\u003eBIOS reporting poor battery health immediately after swapping the cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe BIOS reads health data stored in the old cell's EEPROM and compares it against the new cell's reported state. A fresh cell with no charge history looks wrong to the firmware — it flags it as degraded or unknown. This is not a fault with the replacement. One full discharge-to-hibernate followed by an uninterrupted charge to 100% gives the BIOS enough data to rewrite the learn cycle and clear the warning.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shuts down hard at 20–30% charge shown on screen\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe fuel gauge IC is still calibrated to the old cell's voltage curve. When the new cell hits a steep voltage drop under full CPU and display load, the actual cell voltage falls below the BMS cutoff threshold before the OS gauge reaches 0%. The gauge and the real state of charge are out of sync. Run two or three full discharge-to-hibernate and full-charge cycles — the fuel gauge IC recalibrates against the new cell's curve and the shutdown point shifts back toward 0% where it belongs.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409820287066,"sku":"BWCS-UNT410NB-1","price":104.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43409820319834,"sku":"BWCS-UNT410NB-2","price":118.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43409820352602,"sku":"BWCS-UNT410NB-3","price":129.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-UNT410NB-1.webp?v=1779581113","url":"https:\/\/batteryweb.com\/products\/positivo-master-n100-replacement-battery-111v-4400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
