It fits the GT-P8110 and GTP8110-HA32ARB variants. The flat 233 × 105 × 3.50mm pouch format matches the original cell's physical footprint inside the chassis.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eGT-P8110 and GTP8110-HA32ARB fit:\u003c\/strong\u003e\n    Both variants share the same battery bay dimensions, connector pinout, and BMS communication protocol. One cell covers both 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 the GT-P8110. The BMS accepted the charge cycle, voltage held within spec under combined display and Wi-Fi load, and protection circuitry tripped correctly at low-voltage cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration after swap:\u003c\/strong\u003e\n    After fitting this battery, run the tablet down to automatic shutoff, then charge uninterrupted to 100%. This forces the fuel gauge IC to recalibrate against the new cell's actual capacity curve and clears the inaccurate percentage readings that appear immediately 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\"\u003eWhy the GT-P8110 shuts down at 15–25% remaining after a battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Galaxy Tab 7.7's fuel gauge IC builds a capacity model from data on the old, degraded cell. After fitting a new battery, that model no longer matches the new cell's voltage-to-charge curve. The IC interprets a healthy voltage drop under display and Wi-Fi load as a near-empty cell and triggers shutdown early. One full discharge-to-shutoff followed by an uninterrupted charge to 100% forces the IC to rebuild its curve against the new cell. After that cycle, percentage reporting and cutoff behaviour return to normal.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eFast charging not available after fitting a replacement battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe GT-P8110's charge controller uses a handshake with the battery's protection circuit during the first accepted charge cycle to confirm cell parameters before enabling higher charge rates. Until that first full cycle completes, the controller defaults to standard charge current as a precaution. Plug the tablet into the original Samsung charger and let it run from low charge to 100% without interruption. After that cycle, the controller clears the flag and full charge rate resumes.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426084520026,"sku":"BWCS-SGP811SL-1","price":43.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426084552794,"sku":"BWCS-SGP811SL-2","price":51.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426084585562,"sku":"BWCS-SGP811SL-3","price":56.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SGP811SL-1.webp?v=1779930339","url":"https:\/\/batteryweb.com\/products\/samsung-gt-p8110-replacement-battery-37v-8000mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
