It replaces OEM part numbers EB-BG900BBC, EB-B900BE, EB-B900BK, EB-B900BC, and EB-B900BU. The cell fits the standard S5 battery bay and connects via the original four-contact terminal strip.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eGT-I9600 \/ GT-I9602 \/ GT-I9700 variant coverage:\u003c\/strong\u003e\n    These regional models share the same 3.85V power rail, identical battery bay dimensions, and the same BMS handshake protocol as the standard Galaxy S5 — one cell covers all of them without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through a full charge and discharge on a Galaxy S5 unit. The BMS accepted charge without current limiting, and the protection circuit tripped correctly at the low-voltage cutoff threshold — no anomalous behaviour at either end of the charge curve.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e\n    On first installation, disable fast charging and run one complete discharge-to-charge cycle before normal use. The S5's fuel gauge IC calibrates against the cell's discharge curve — skipping this step causes the coulomb counter to report against the old cell's profile, producing inaccurate percentage readings for days.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Galaxy S5 reports wrong battery percentage after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe S5 uses a coulomb counter in its fuel gauge IC to track charge state. After a cell swap, the counter still holds calibration data from the degraded original battery — a cell with a shrunken discharge curve and higher internal resistance. The new cell has a different discharge curve, so the IC maps percentage readings against the wrong reference profile. One full discharge cycle below 3.0V followed by a full charge to 4.35V resets the calibration anchor and brings percentage reporting back to accuracy.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSudden shutdown at 20–30% on a replacement cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the phone's modem or display pulls a current spike the cell cannot sustain at that state of charge, causing a momentary voltage sag below the BMS cutoff threshold — the BMS reads the sag as a dead cell and shuts the phone down. It is most common in the first few cycles before the fuel gauge IC has recalibrated to the new cell's voltage curve. Run two full discharge-charge cycles and check whether the shutdowns persist. If the cell voltage reads below 3.5V at the moment of shutdown, the BMS cutoff is triggering correctly on a genuine sag — allow the cell to complete more calibration cycles before drawing conclusions.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43404274270298,"sku":"BWCS-SMI960DL-1","price":41.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43404274303066,"sku":"BWCS-SMI960DL-2","price":48.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43404274335834,"sku":"BWCS-SMI960DL-3","price":53.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SMI960DL-1.webp?v=1779369616","url":"https:\/\/batteryweb.com\/products\/samsung-galaxy-s5-replacement-battery-385v-5600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
