It fits the Inspiron 11-3137, 11-3138, and 11-3197 alongside the 3135. The OEM part numbers CGMN2, N33WY, NYCRP, and 0CGMN2 all cross-reference to this cell.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eInspiron 11 3000-series fit:\u003c\/strong\u003e\n    These models share a common 11.4V three-cell architecture and the same P19T board connector. The BMS handshake protocol is identical across P19T001, P19T002, and P19T003 variants, so one cell covers the full range without firmware conflicts.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell on a P19T002 board and confirmed full charge acceptance, accurate state-of-charge reporting, and clean BMS communication throughout the cycle. No trip events or cell-rejection flags appeared during testing.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration:\u003c\/strong\u003e\n    After fitting this battery, run the laptop 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 Dell Inspiron systems.\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 fitting a new cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eDell's BIOS reads EEPROM data embedded in the battery controller to assess health. When a new cell is installed, that EEPROM carries factory default values the BIOS hasn't yet validated against real charge cycles. The firmware flags this as degraded health until it completes a learn cycle. Run one full discharge to hibernate, then a full uninterrupted charge — the BIOS re-evaluates and the warning clears.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shuts down abruptly at 20–30% charge shown\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a voltage cliff issue, not a capacity fault. Under combined CPU and display load, cell voltage drops faster than the fuel gauge IC can track, and the system hits the low-voltage cutoff before the reported percentage reaches zero. The gauge IC needs two or three calibration cycles against the new cell to map the discharge curve accurately. Run full discharge-to-hibernate cycles until the shutdown point tracks closer to 5% — on Dell Inspiron hardware this typically stabilises by the third cycle.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409775099994,"sku":"BWCS-DE3135NB-1","price":75.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409775132762,"sku":"BWCS-DE3135NB-2","price":88.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409775165530,"sku":"BWCS-DE3135NB-3","price":98.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-DE3135NB-1.webp?v=1779580819","url":"https:\/\/batteryweb.com\/products\/dell-inspiron-3135-replacement-battery-114v-4300mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
