It fits the GT-P7300, GT-P7310, and GT-P7320 variants. Swap it in when the original cell no longer holds a usable charge or fails to power the tablet past the boot screen.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eGT-P7300, GT-P7310, GT-P7320 compatibility:\u003c\/strong\u003e\n    All three variants share the same battery bay dimensions, connector pinout, and charge IC communication protocol — one cell fits the full range 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 cycles on the GT-P7300. The BMS held charge termination correctly at 4.2V and low-voltage cutoff triggered cleanly before cell damage thresholds were reached.\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-power-off — then charge uninterrupted to 100% without unplugging. This gives the fuel gauge IC a full reference cycle against the new cell and clears the inaccurate percentage readings that appear immediately post-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% remaining after battery replacement\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Galaxy Tab 8.9 pulls significant current when the display is at full brightness with Wi-Fi active. A new cell whose fuel gauge IC has not been calibrated will report a higher state-of-charge than the actual cell voltage supports under that load. The processor sees a sudden voltage drop below the cutoff threshold and shuts down before the reported percentage reaches zero. One full discharge-to-shutoff cycle followed by an uninterrupted charge to 100% corrects the gauge reference and eliminates these premature shutoffs.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eFast charging not available after fitting the SP368487A\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Tab 8.9 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. If the first charge after installation was interrupted — cable pulled, tablet restarted, or power lost — the handshake completes only partially. Connect the tablet to its original charger, allow one full uninterrupted charge from any charge level to 100%, and fast charge availability will restore at the next session.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426089730138,"sku":"BWCS-SGP730SL-1","price":39.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426089762906,"sku":"BWCS-SGP730SL-2","price":46.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426089795674,"sku":"BWCS-SGP730SL-3","price":51.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SGP730SL-1.webp?v=1779930340","url":"https:\/\/batteryweb.com\/products\/samsung-galaxy-tab-89-replacement-battery-37v-6100mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
