It fits the GT-N5100, GT-N5110, and Galaxy Note 8.0 32GB variants. If your original SP3770E1H has swollen, dropped capacity, or stopped holding a charge, this is the direct OEM part number match.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eGT-N5100 and GT-N5110 compatibility:\u003c\/strong\u003e\n    Both variants share the same 3.7V power rail, connector pinout, and BMS handshake protocol — the same SP3770E1H cell fits both without modification. Swapping between these models is not supported; the battery is specific to this Note 8.0 platform.\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 a GT-N5100 unit. The BMS accepted the cell cleanly, thermal limits held within spec, and voltage under combined display and Wi-Fi load stayed stable without dipping below the cutoff threshold.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation fuel gauge reset:\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 recalibrates the fuel gauge IC against the new cell and clears the inaccurate percentage reading that typically appears right 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 Note 8.0 shutting down at 15–25% remaining\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe GT-N5100 draws hard from the battery when the display runs at full brightness alongside active Wi-Fi or data sync. At around 15–25% state of charge, the cell voltage drops quickly under that combined load. The BMS reads this voltage cliff as a critically low cell and triggers an immediate shutdown before the reported percentage reaches zero. Running the full discharge-to-shutoff recalibration cycle after installation brings the fuel gauge back into alignment with actual cell voltage and eliminates most of these premature cutoffs.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eFast charging unavailable after battery replacement on Note 8.0\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eSome GT-N5100 units show standard charge speed only — not fast charge — after a battery swap. The charge IC needs one completed accepted charge cycle before it re-negotiates the correct charging profile with a new cell. Plug the tablet into the original Samsung charger, let it complete a full uninterrupted charge to 100%, and confirm the charge current on the next cycle. If fast charge remains absent after two full cycles, check that the charger output matches Samsung's spec of 5V\/2A for this tablet.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426073870426,"sku":"BWCS-SGP510SL-1","price":28.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426073903194,"sku":"BWCS-SGP510SL-2","price":32.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426073935962,"sku":"BWCS-SGP510SL-3","price":35.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SGP510SL-1.webp?v=1779930340","url":"https:\/\/batteryweb.com\/products\/samsung-gt-n5100-replacement-battery-37v-3000mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
