It fits SM-T280, SM-T285, and SM-T285M tablets. OEM part numbers EB-BT280ABA, EB-BT280ABE, and GH43-04588A all cross to this same cell.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSM-T280 and SM-T285 compatibility:\u003c\/strong\u003e\n    Both variants run the same 3.8V power rail and use the same flex connector and BMS handshake. One cell covers the Wi-Fi-only SM-T280 and the LTE SM-T285 — the charge IC makes no distinction between the two.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge and discharge on an SM-T285 unit. The BMS accepted charge from the first connection, reported state-of-charge to the OS without error, and held voltage within spec across the discharge curve.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration after swap:\u003c\/strong\u003e\n    After installing this battery, run the tablet down to automatic shutoff, then charge uninterrupted to 100% without using the device. This one full cycle resets the fuel gauge IC against the new cell and clears the inaccurate percentage readings that almost always appear after a swap.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTablet shutting down at 15–25% after battery replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe fuel gauge IC in the SM-T280 and SM-T285 stores a learned voltage curve from the old cell. When a new cell is installed, that stored curve no longer matches the real voltage-to-capacity relationship of the replacement. The tablet interprets a normal mid-range voltage dip — caused by the display backlight and LTE radio drawing current simultaneously — as a critically low state, and shuts down to protect the hardware. One full discharge-to-shutoff followed by an uninterrupted charge to 100% resets that learned curve against the new cell. After that cycle, shutdowns at 15–25% stop.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eFast charging unavailable on the Tab E 7.0 after the battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eSamsung's Adaptive Fast Charging requires the charge IC to complete at least one full accepted charge cycle before it negotiates higher current from a compatible charger. On a fresh cell install, the IC starts in a conservative mode and steps up only after it has profiled the new cell's internal resistance. Use a genuine Samsung AFC charger for the first charge and let it complete fully without interruption. After that initial cycle, the fast charge handshake re-enables at the correct voltage step.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43425898463322,"sku":"BWCS-SMT280SL-1","price":28.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43425898496090,"sku":"BWCS-SMT280SL-2","price":32.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43425898528858,"sku":"BWCS-SMT280SL-3","price":35.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SMT280SL-1.webp?v=1779930025","url":"https:\/\/batteryweb.com\/products\/samsung-galaxy-tab-e-70-2016-4g-lte-replacement-battery-38v-4000mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
