It fits SM-G750, SM-G750A, SM-G750F, SM-G7508, and additional SM-G750 variants. Use this when the original cell no longer holds adequate charge for normal daily use.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSM-G750 variant compatibility:\u003c\/strong\u003e\n    All SM-G750 variants share the same 3.8V voltage rail, the same EB-BG750BBC connector footprint, and the same BMS handshake with the Galaxy Mega 2's charge IC — so one cell covers the full model range 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-discharge cycles on the SM-G750 platform. The BMS negotiated correctly with the device's charge IC, and protection cutoffs triggered at expected thresholds under both idle and active screen load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle fuel gauge recalibration:\u003c\/strong\u003e\n    On first use after installation, disable fast charging and run one full discharge-charge cycle from 100% down to automatic cutoff and back to full. This lets the fuel gauge IC map 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 Galaxy Mega 2 after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Galaxy Mega 2's fuel gauge IC retains the discharge curve from the old cell after replacement. When the new cell hits a voltage cliff under modem or display load, the IC hasn't yet learned where that cliff sits — so the phone cuts out even though the percentage shown looks safe. One complete discharge-charge cycle with fast charging disabled forces the coulomb counter to rebuild its model against the new cell. After that cycle, the reported percentage tracks actual cell voltage accurately.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eGalaxy Mega 2 not powering on after sitting in storage with a new battery installed\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells stored below 2.5V per cell trigger a BMS deep-discharge lockout — the battery refuses to output current as a protection measure. The SM-G750 won't boot from this state because the board never receives enough voltage to initialise. Connect the device to a wall charger, not a PC USB port, and leave it for 15–20 minutes without pressing the power button. The charger's constant-voltage trickle will bring the cell above the BMS recovery threshold, after which normal charging resumes — verify the charging indicator appears on screen before disconnecting.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43404219580506,"sku":"BWCS-SMG750SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43404219613274,"sku":"BWCS-SMG750SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43404219646042,"sku":"BWCS-SMG750SL-3","price":29.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SMG750SL-1.webp?v=1779369425","url":"https:\/\/batteryweb.com\/products\/samsung-sm-g750-replacement-battery-38v-2500mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
