It fits SM-A310 and SM-A310Y variants and slots into the same battery bay as the OEM unit. OEM part references are EB-BA310ABE and GH43-04562A.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSM-A310 series fit:\u003c\/strong\u003e\n    The A3 2016 lineup shares a single battery footprint — 84.60 × 36.95 × 4.70mm — with identical connector placement and BMS pin layout across SM-A310, SM-A310Y, and the LTE variant. The same 3.85V voltage rail and communication protocol runs across all listed models.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell in an SM-A310 unit and confirmed stable BMS handshake at full charge and at low-state discharge. The protection circuit tripped correctly at undervoltage and the charge IC accepted a standard charge profile without errors.\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 down to automatic shutdown, then charge uninterrupted to 100%. This gives the fuel gauge IC a clean reference cycle against the new cell's discharge curve before high-current charging is applied.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Galaxy A3 2016 reports wrong battery percentage after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe A3 2016 uses a coulomb counter inside the fuel gauge IC that was calibrated against the original cell's discharge curve. When you fit a new cell, that stored curve no longer matches the new cell's actual voltage-versus-capacity behaviour. The IC keeps reporting percentages based on old data until it learns the new curve. One full discharge-to-shutdown followed by an uninterrupted charge to 100% resets the reference points the fuel gauge uses. After that cycle, percentage readings track the real state of charge accurately.\u003c\/p\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\"\u003eThis is a voltage cliff issue, not a capacity fault. Under high-current draw — mobile data radio, screen at full brightness, or intensive app use — the cell voltage sags faster than the fuel gauge predicts, dropping below the BMS cutoff threshold before the displayed percentage reaches zero. A freshly installed cell with an uncalibrated fuel gauge IC is most vulnerable to this on the first few cycles. Run that initial full discharge-charge cycle and the fuel gauge IC will map the sag curve correctly. If shutdowns persist past three full cycles, check that the battery connector is fully seated — a high-resistance connection amplifies voltage sag under load.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43392096043098,"sku":"BWCS-SMA320SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43392096075866,"sku":"BWCS-SMA320SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43392096108634,"sku":"BWCS-SMA320SL-3","price":28.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SMA320SL-1.webp?v=1779143764","url":"https:\/\/batteryweb.com\/products\/samsung-galaxy-a3-2016-replacement-battery-385v-1700mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
