It replaces OEM part numbers EB-B130BE, EB-BG313BBE, and GH43-04256A. Fit it when the original cell no longer holds charge through a normal day of use.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSM-G310 series compatibility:\u003c\/strong\u003e\n    All SM-G310 variants share the same battery bay dimensions, connector pinout, and BMS handshake protocol. The 59.73 × 50.48 × 4.25mm cell slots directly into the same physical cavity without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell on an SM-G310H unit and confirmed the BMS completed a full charge cycle without tripping low-voltage cutoff. Charge acceptance was stable from 3.0V up to the 4.35V termination point the device expects.\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-to-charge cycle. This gives the fuel gauge IC time to map the new cell's discharge curve before it begins tracking state-of-charge. Skipping this step is why many users see erratic percentage readings in the first day.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the SM-G310 reports wrong battery percentage after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eSamsung's fuel gauge IC stores a learned discharge curve from the previous cell. When a new cell goes in, that stored curve no longer matches the actual voltage-to-capacity relationship of the replacement. The IC keeps reading against the old data until it runs a full cycle and relearns. This causes the percentage to jump or freeze at values that don't reflect real charge state. One full uninterrupted discharge followed by a full charge resolves it.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSudden shutdown at 20–30% on the SM-G310\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the cell voltage drops below what the modem or display load requires, even though the reported percentage still looks safe. The fuel gauge IC is reading a stale discharge curve and misreports remaining capacity right before the cell hits its voltage floor. Under burst load — a call, a screen wake, mobile data — the cell can't sustain voltage and the protection circuit cuts out instantly. After completing a full recalibration cycle, check that shutdown no longer occurs above 3.5V terminal voltage.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43404242124890,"sku":"BWCS-SMG310XL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43404242157658,"sku":"BWCS-SMG310XL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43404242190426,"sku":"BWCS-SMG310XL-3","price":28.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/batteryweb.com\/products\/samsung-sm-g310-replacement-battery-38v-1500mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
