It fits the SM-G3588, SM-G3588V, SM-G3588D, and SM-G3556 among others. The OEM part numbers are EB-BG358BBC and EB-BG358BBE.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSM-G3588 series compatibility:\u003c\/strong\u003e\n    These variants share the same 3.7V power rail, identical connector pinout, and the same BMS handshake protocol — 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 cycled this cell on an SM-G3588 unit and confirmed the BMS accepted the new cell without triggering a charge-suspend fault. Capacity held within 3% of rated across the first three cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\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 map the new cell's discharge curve before the charge IC pushes higher 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 replacement cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Galaxy Core 2's fuel gauge IC carries over the discharge curve calibrated to the old, degraded cell. When the new cell hits a voltage point the IC wasn't expecting, it interprets a sharp voltage drop as empty and cuts power — even though capacity remains. The modem and display load together can cause a short current spike that drops cell voltage below the BMS cutoff threshold at that miscalibrated point. Run one full discharge to below 5% and charge to 100% without interruption. After that single cycle, the coulomb counter resets and the shutdowns stop.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePhone not powering on after the battery sat discharged in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells that drop below approximately 2.5V trip the BMS into a lockout state — the protection circuit disconnects the cell to prevent damage, and the phone sees no voltage at all. A standard charger may not deliver enough trickle current to wake the cell from lockout. Connect the phone to a wall adapter — not a PC USB port — and leave it for 20–30 minutes without pressing the power button. If the charging LED activates, the BMS has re-initialised; allow a full charge before booting.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43404227936346,"sku":"BWCS-SMG360XL-1","price":24.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43404227969114,"sku":"BWCS-SMG360XL-2","price":27.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43404228001882,"sku":"BWCS-SMG360XL-3","price":30.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SMG360XL-1.webp?v=1779369425","url":"https:\/\/batteryweb.com\/products\/samsung-sm-g3588-replacement-battery-37v-2000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
