It fits the Samsung Galaxy A3 2017 and all SM-A320 variants, including the SM-A320FL and the TD-LTE model lines. Voltage and physical dimensions match the OEM cell exactly — 74.30 × 39.40 × 4.90mm.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSM-A320 variant compatibility:\u003c\/strong\u003e\n    The SM-A320, SM-A320FL, and TD-LTE variants share the same battery bay geometry, connector pinout, and 3.85V nominal rail. One cell covers all of them 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 and discharge on a Galaxy A3 2017 unit. The BMS accepted the cell, charge IC ramped normally, and no fault codes triggered on the protection circuit during CC-CV transition.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e\n    After installation, disable fast charging and run one full discharge-charge cycle at standard rate. This lets the fuel gauge IC map its coulomb counter against the new cell's actual discharge curve before high-current charging begins on 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 A3 2017 after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Galaxy A3 2017's fuel gauge IC retains the discharge curve from the old, degraded cell. When a new cell with a steeper voltage cliff at low state-of-charge is installed, the IC misjudges the remaining capacity. The phone's modem or display pulls current, voltage drops below the protection threshold, and the device cuts out — even though the reported percentage still reads 20–30%. One full discharge to auto-shutdown followed by a complete charge cycle forces the coulomb counter to re-anchor to the new cell's curve.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDevice will not power on after the replacement cell sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-Polymer cells self-discharge in storage. If this cell shipped at a low state of charge and sat unused, the cell voltage may have dropped below 2.5V — the threshold at which the BMS trips into deep-discharge lockout to prevent permanent damage. Plugging in a charger may show nothing for several minutes while the charge IC trickle-charges the cell back above the BMS re-enable threshold. Use the OEM Samsung charger or a 5V\/1A source and leave it connected for at least 15 minutes before attempting to power on.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43392081723482,"sku":"BWCS-SMA327SL-1","price":24.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43392081756250,"sku":"BWCS-SMA327SL-2","price":27.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43392081789018,"sku":"BWCS-SMA327SL-3","price":30.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SMA327SL-1.webp?v=1779143638","url":"https:\/\/batteryweb.com\/products\/samsung-galaxy-a3-2017-replacement-battery-385v-2350mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
