It fits the Samsung SGH-T769, Galaxy S Blaze 4G, SGH-i577, and Exhilarate. Swap it when the original cell no longer holds a charge or triggers unexpected shutdowns.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSGH-T769 and Blaze 4G platform:\u003c\/strong\u003e\n    These four models share the same battery bay dimensions, connector pinout, and BMS handshake protocol — a single 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 ran this cell through charge and discharge cycles on the SGH-T769. The BMS accepted the cell, reported voltage correctly, and thermal behaviour stayed within normal range at full charge current.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration after install:\u003c\/strong\u003e\n    On first use, disable fast charging and run one full discharge down to auto-shutoff, then charge uninterrupted to 100%. This gives the fuel gauge IC one clean cycle to map the new cell's discharge curve before taking readings it will report to the OS.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the SGH-T769 reports wrong battery percentage after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe phone's fuel gauge IC stores a charge curve calibrated to the original cell. When you install a new cell, the IC still references that old curve, so the percentage readout drifts — often reading higher or lower than actual charge state. This is not a fault in the replacement cell. One complete discharge-to-shutoff followed by an uninterrupted charge to 100% resets the coulomb counter against the new cell's actual capacity. After that cycle, percentage reporting stabilises.\u003c\/p\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\"\u003eThe SGH-T769 draws a sharp current spike when the modem transmits or the screen brightness jumps. If the fuel gauge IC is still uncalibrated after a cell swap, it can report 25% while the actual cell voltage has already dropped near the BMS cutoff threshold of around 3.0V. The BMS trips and the phone shuts off — not because the cell is faulty, but because the gauge and the cell are out of sync. Run the full recalibration cycle first: discharge fully to auto-shutoff, then charge straight to 100% without interruption.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43405037600858,"sku":"BWCS-SMT769XL-1","price":24.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43405037633626,"sku":"BWCS-SMT769XL-2","price":27.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43405037666394,"sku":"BWCS-SMT769XL-3","price":30.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SMT769XL-1.webp?v=1779369859","url":"https:\/\/batteryweb.com\/products\/samsung-sgh-t769-replacement-battery-37v-1750mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
