It fits the SM-G9650\/DS, SM-G965N, and related variants sharing the EB-BG965ABE form factor. Capacity matches the factory specification at 13.48Wh.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSM-G965 series fit:\u003c\/strong\u003e\n    All SM-G965 variants use the same 78.68 × 45.56 × 5.60mm cell envelope, the same flex connector pinout, and communicate with the charge IC over the same BMS protocol — which is why one cell covers the full range of regional model numbers.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through a full charge and discharge cycle on an SM-G965F. The BMS handshook correctly with Samsung's charge IC on first contact, and the coulomb counter initialised without error flags in the battery status register.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle calibration tip:\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 charging is applied to 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 replacement cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a voltage cliff issue, not a capacity defect. Under peak modem or display load, the cell voltage can drop sharply below the threshold the OS uses to predict remaining charge — triggering a protective shutdown before the gauge reads zero. It happens most often in the first few cycles on a fresh cell because the fuel gauge IC is still calibrated to the old, degraded discharge curve. Running one full discharge to shutdown followed by a complete charge resets the coulomb counter reference and typically eliminates the early cutoff.\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\"\u003eAfter a cell swap, Samsung's Adaptive Fast Charging negotiation can stall on the first charge cycle — the phone falls back to standard 5V\/1A input even when a fast charger is connected. This happens because the charge IC runs a brief conditioning pass on an unknown cell before it allows elevated current. Disconnect the charger, power the phone fully off, then reconnect — the IC re-enters negotiation from a clean state. Fast charge typically resumes normally from the second cycle onward.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43392022577242,"sku":"BWCS-SMG965XL-1","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43392022610010,"sku":"BWCS-SMG965XL-2","price":28.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43392022642778,"sku":"BWCS-SMG965XL-3","price":31.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SMG965XL-1.webp?v=1779142963","url":"https:\/\/batteryweb.com\/products\/samsung-galaxy-s9-plus-replacement-battery-385v-3500mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
