It restores power to the 8-inch Android tablet when the original cell has degraded, swollen, or stopped holding a usable charge. Capacity matches the factory spec at 15.96Wh.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSM-T350 and SM-P350 compatibility:\u003c\/strong\u003e\n    Both models share the same 3.8V battery bay, connector pinout, and BMS handshake protocol — one cell fits the full production run of the Galaxy Tab A 8.0 across both Wi-Fi and LTE variants.\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 cycles on the SM-T350. The BMS accepted the charge profile without fault codes, and the protection circuit responded correctly to over-discharge cutoff at the expected low-voltage threshold.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration after install:\u003c\/strong\u003e\n    After fitting this battery, run the tablet down to automatic shutoff — do not force it off — then charge uninterrupted to 100%. This gives the fuel gauge IC a full reference window against the new cell and clears the inaccurate percentage readings that commonly 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\"\u003eGalaxy Tab A 8.0 shutting down between 15–25% remaining\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens because the display and Wi-Fi radio draw simultaneously during streaming or browsing, which creates a combined load spike the fuel gauge IC cannot anticipate accurately. The voltage drops sharply under that load — faster than the reported percentage suggests — and the BMS triggers a protective cutoff before the displayed figure reaches zero. It is more common with a new cell because the fuel gauge is still calibrated to the old cell's discharge curve. One complete discharge-to-shutoff followed by an uninterrupted charge to 100% recalibrates the reference and typically resolves the early shutdown.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eFast charging unavailable after battery replacement on SM-T350\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe SM-T350 uses Samsung's Adaptive Fast Charging protocol, which requires the charge IC and the battery's BMS to complete a successful handshake before the charger steps up to higher voltage. On a freshly installed cell, this negotiation sometimes fails on the first charge cycle because the BMS has no prior session data. Use the original Samsung charger — not a third-party USB-C adapter — and allow the first charge to complete fully without interruption. Fast charge availability typically restores from the second cycle onward once the handshake has been accepted.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43425887846490,"sku":"BWCS-SMT350SL-1","price":28.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43425887879258,"sku":"BWCS-SMT350SL-2","price":32.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43425887912026,"sku":"BWCS-SMT350SL-3","price":35.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SMT350SL-1.webp?v=1779930025","url":"https:\/\/batteryweb.com\/products\/samsung-sm-t350-replacement-battery-38v-4200mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
