It replaces OEM part numbers EB-BN965ABE and EB-BN965ABU. The cell restores full power delivery to the display, processor, modem, and S Pen detection circuitry.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eNote 9 regional variants covered:\u003c\/strong\u003e\n    The SM-N960 series spans multiple carrier and regional builds, but all share the same battery bay geometry, connector pinout, and BMS handshake protocol — one cell covers the full lineup without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell in an SM-N960U and confirmed the BMS negotiated charge current correctly with the on-board charge IC, held voltage through a full display-on load cycle, and passed the connector retention check without flex on the tab.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e\n    On first use after installation, disable fast charging for one complete discharge-charge cycle. This lets the fuel gauge IC recalibrate against the new cell's discharge curve before high-current fast charging pushes current into an uncalibrated cell.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSudden shutdown at 20–30% on the Note 9 after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Note 9's fuel gauge IC stores a learned discharge curve from the original cell. A new cell has a steeper voltage cliff under modem and display load at lower states of charge. When the fuel gauge reads 20–30%, the actual cell voltage can drop below the modem's minimum rail — the phone cuts out even though the reported percentage looks safe. One full discharge-to-shutdown followed by a complete charge resets the coulomb counter and maps the new curve correctly. After that cycle, shutdowns at 20–30% should not repeat.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eUSB-PD fast charge not accepted on the first cycle after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eSome Note 9 units reject Adaptive Fast Charging on the first charge cycle after a battery swap — the charge IC briefly flags the new cell's impedance as out of range and defaults to standard 5V charging. This is not a fault with the battery or the charger. Charge the device once on a standard 5W adapter to full, then reconnect your fast charger — the charge IC re-evaluates cell impedance at a known state of charge and typically accepts fast charging from that point forward.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43392015532122,"sku":"BWCS-SMN960XL-1","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43392015564890,"sku":"BWCS-SMN960XL-2","price":28.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43392015597658,"sku":"BWCS-SMN960XL-3","price":31.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SMN960XL-1.webp?v=1779142921","url":"https:\/\/batteryweb.com\/products\/samsung-galaxy-note-9-replacement-battery-385v-4000mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
