It matches the OEM dimensions at 58.60 × 45.94 × 5.00mm and uses the same connector pinout as the factory cell. Voltage and capacity are drawn directly from the product specification — 5.55Wh total energy.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSGH-T759 \/ Exhibit 4G platform fit:\u003c\/strong\u003e\n    These models share the same battery bay geometry, 3.7V nominal voltage rail, and three-pin connector with integrated NTC thermistor line. The charge IC in each device reads the same thermistor response, so no BMS handshake is required beyond a standard Li-ion charge profile.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through full charge and load discharge on the SGH-T759 platform. The charge IC accepted the cell immediately, thermistor readings stayed within spec, and the BMS did not trigger a lockout at either end of the voltage range.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e\n    On the first install, disable fast charging if your carrier or ROM supports it, then run one complete discharge-to-charge cycle at standard current. This lets the fuel gauge IC map its coulomb counter against the new cell's actual discharge curve before any high-current session skews the baseline reading.\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-T759 shuts down suddenly at 20–30% after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe phone's fuel gauge IC retains the discharge curve it learned from the old, degraded cell. When load spikes — modem TX bursts or screen-on events — the new cell briefly sags in voltage at a point the IC still maps as 20–30% remaining. The hardware voltage floor trips a hard shutdown before the IC can correct itself. One full manual discharge cycle, letting the phone reach the OS low-battery warning and then charging uninterrupted to 100%, resets the learned curve and eliminates most premature shutoffs.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePhone won't power on after the replacement battery sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge roughly 2–3% per month in storage. If this cell sat long enough to drop below 2.5V per cell, the BMS enters a lockout state to prevent damage and will not respond to a normal power-on attempt. Connect the phone to a wall charger — not a PC USB port — and leave it for 20–30 minutes without pressing the power button. The charge IC will trickle-charge the cell back above the BMS re-enable threshold, typically around 2.8–3.0V, after which a normal boot will succeed.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43405058834522,"sku":"BWCS-SMT759XL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43405058867290,"sku":"BWCS-SMT759XL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43405058900058,"sku":"BWCS-SMT759XL-3","price":28.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SMT759XL-1.webp?v=1779369899","url":"https:\/\/batteryweb.com\/products\/samsung-sgh-t759-replacement-battery-37v-1500mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
