It fits the 8.0-inch rugged Android tablet released in 2020. Install it when the original cell no longer holds a full charge or fails to power on at all.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSM-T570 series compatibility:\u003c\/strong\u003e\n    The Galaxy Tab Active 3 variants — including the SM-T570, SM-T575, and SM-T577 — share the same battery bay dimensions, connector pinout, and BMS handshake protocol. All units accept the EB-BT575BBE cell 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-T575 unit and confirmed full charge acceptance via the onboard charge IC. The BMS communicated correctly with Android's battery service, reporting voltage and charge state without error flags.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration after swap:\u003c\/strong\u003e\n    After installing this battery, run one complete discharge to automatic shutoff — do not force-off the tablet — then charge uninterrupted to 100%. This resets the fuel gauge IC calibration against the new cell. Skip this step and the percentage display will drift from the first cycle.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Tab Active 3 shuts down at 15–25% remaining after a battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Galaxy Tab Active 3 uses a fuel gauge IC that stores learned discharge curves from the previous cell. When a new cell is installed, the IC still applies the old curve, which maps the wrong voltage to a given percentage. Under combined screen-plus-WiFi load, voltage drops faster than the IC predicts, triggering a low-voltage protection cutoff while the display still reads 15–25%. One full uncalibrated discharge-to-shutoff cycle teaches the IC the actual voltage floor of the new cell — typically 3.4V — and eliminates premature cutoffs.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eFast charging unavailable on the Tab Active 3 after battery replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Tab Active 3 supports Samsung Adaptive Fast Charging, which requires the charge IC to complete one recognised full charge cycle before it unlocks higher charge rates on a new cell. If fast charge is absent immediately after installation, connect the original Samsung charger and allow the tablet to charge from low to 100% without interruption. After that first accepted cycle, the charge IC re-enables the higher current profile. Using a third-party charger for this first cycle can prevent the handshake from completing — use the OEM adapter.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43425829159002,"sku":"BWCS-SMT570SL-1","price":35.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43425829191770,"sku":"BWCS-SMT570SL-2","price":41.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43425829224538,"sku":"BWCS-SMT570SL-3","price":45.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/batteryweb.com\/products\/samsung-galaxy-tab-active-3-replacement-battery-385v-4900mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
