It replaces OEM part EB-BG890ABA directly. Rated at 3.85V nominal and 13.48Wh total energy.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSM-G890 and SM-G890A fit:\u003c\/strong\u003e\n    Both variants share the same battery bay dimensions, connector pinout, and BMS handshake protocol. The EB-BG890ABA spec covers both SKUs — no hardware differences affect this battery swap.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell on an SM-G890A and confirmed BMS communication, charge acceptance across all stages, and fuel gauge IC readout stability after one full discharge cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle fast charge calibration:\u003c\/strong\u003e\n    On first use after installation, disable fast charging and run one complete discharge-charge cycle. This lets the fuel gauge IC recalibrate against the new cell's discharge curve before high-current 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 S6 Active after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the fuel gauge IC is still calibrated to the old cell's discharge curve. A fresh Li-Polymer cell has a steeper voltage drop near the lower end of its curve than a degraded original cell. The phone reads 25% but the cell voltage has already dropped below the safe floor under modem or screen load, triggering an emergency shutdown. One full uninterrupted discharge-charge cycle resets the coulomb counter and aligns the percentage display to the new cell's actual curve.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eUSB fast charge not activating on the first cycle after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eOn the first charge after installation, the charge IC may default to standard 5V\/1A input until it confirms BMS readiness on the new cell. This is a protective handshake — the charger will not step up to fast-charge voltage on an uncalibrated cell. Let the phone charge fully once on standard power, then fast charging will negotiate normally on subsequent cycles. If fast charging still does not engage after two full cycles, check that the USB-C cable supports the required current rating.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43404154732634,"sku":"BWCS-SMG890SL-1","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43404154765402,"sku":"BWCS-SMG890SL-2","price":29.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43404154798170,"sku":"BWCS-SMG890SL-3","price":32.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SMG890SL-1.webp?v=1779369094","url":"https:\/\/batteryweb.com\/products\/samsung-galaxy-s6-active-replacement-battery-385v-3500mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
