It replaces OEM part numbers N350BAT-6, N350BAT-9, 6-87-N350S-4D7, and 6-87-N350S-4D8. The physical dimensions are 204.90 × 49.10 × 19.90mm — confirm clearance before fitting.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eN350 platform compatibility:\u003c\/strong\u003e\n    The N350DV, N350DW, and B519II(N350TW) variants share the same battery bay dimensions, connector pinout, and BMS communication protocol. All four OEM part numbers above cross to this cell — the suffix differences reflect minor PCB revisions, not electrical changes.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell on an N350DV chassis. The BMS handshook correctly on first insertion, charge current ramped normally from CC to CV phase, and the protection circuit tripped at the expected over-discharge threshold without requiring a manual reset.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration on the N350 platform:\u003c\/strong\u003e\n    After fitting, run the laptop on battery until it drops to hibernate-cutoff, then charge uninterrupted to 100% without interruption. This resets the BIOS battery learn cycle and clears the inaccurate health warning the N350's firmware throws 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\"\u003eBIOS reporting battery health as poor immediately after fitting a new cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe N350 platform stores charge history and wear data in EEPROM on the battery's PCB. When a new cell is installed, the BIOS reads that EEPROM as blank or mismatched and flags poor health — this is a firmware interpretation issue, not a defective battery. The fix is a full discharge-to-hibernate followed by a complete uninterrupted charge to 100%. After one or two of these learn cycles, the BIOS fuel gauge IC recalibrates against the new cell's actual chemistry and the warning clears.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shutting down abruptly at 20–30% charge shown on screen\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the cell's voltage drops below the CPU-plus-display load threshold faster than the fuel gauge IC predicts — a voltage cliff that the old cell's calibration data can't map to a new cell. The OS percentage reading is based on a learned discharge curve that no longer matches the replacement cell. Run two full discharge-to-cutoff and uninterrupted full-charge cycles to force the fuel gauge IC to build a new curve against the actual cell. After calibration, shutdowns should stop occurring above 10–11V under load.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409588519002,"sku":"BWCS-CLN350NB-1","price":94.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409588551770,"sku":"BWCS-CLN350NB-2","price":110.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409588584538,"sku":"BWCS-CLN350NB-3","price":123.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CLN350NB-1.webp?v=1779580129","url":"https:\/\/batteryweb.com\/products\/clevo-n350dv-replacement-battery-111v-5200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
