It fits the same slot, uses the same connector, and works with the phone's onboard charge controller. If your Grand Prime no longer holds charge or shuts down unexpectedly, this is the direct cell swap.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eGrand Prime compatibility:\u003c\/strong\u003e\n    The SM-G530H\/DS shares its battery bay and BMS handshake across several Grand Prime variants. Samsung used multiple OEM part numbers — EB-BG530BBE, EB-BG530CBB, EB-BG530CBE, GH43-04372A — for the same cell form factor, so one replacement covers the full lineup without connector or voltage rail changes.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through the SM-G530H charge cycle. The BMS accepted the full 2400mAh charge without cutoff errors, and the charge IC logged no overcurrent flags on the first cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle fuel gauge recalibration:\u003c\/strong\u003e\n    After installing this cell, disable fast charging and run one complete discharge-to-charge cycle before normal use. The Grand Prime's fuel gauge IC is calibrated to the old cell's discharge curve. One full cycle at standard current lets it recalibrate against the new cell before high-current charging begins.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Grand Prime reports wrong battery percentage after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe SM-G530H uses a coulomb counter inside the fuel gauge IC to track charge state. That counter was calibrated against the original cell's impedance and discharge curve over months of use. When a new cell goes in, the stored calibration data no longer matches the actual cell chemistry. The phone reads a voltage-to-percentage map that's off by 10–20% until the IC relearns the curve. One full discharge below 5% followed by a complete charge to 100% at standard current resets the calibration baseline.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSudden shutdown at 20–30% remaining on the Grand Prime\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a voltage cliff failure. The Grand Prime's modem and display together pull enough current that a degraded or brand-new uncalibrated cell drops below the BMS cutoff threshold — typically 3.4V — even though the fuel gauge still shows 20–30%. The phone cuts off to protect the cell, not because the percentage is wrong per se, but because instantaneous voltage sags under load. After the first calibration cycle, verify the cell holds above 3.6V under screen-on load; if it still drops out, check that the battery contacts on the chassis are clean and making full contact.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43404219678810,"sku":"BWCS-SMG530SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43404219711578,"sku":"BWCS-SMG530SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43404219744346,"sku":"BWCS-SMG530SL-3","price":29.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SMG530SL-1.webp?v=1779369425","url":"https:\/\/batteryweb.com\/products\/samsung-replacement-battery-38v-2400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
