It fits the SM-T900, SM-T905, Galaxy TabPRO 12.2, and Galaxy TabPRO 12.2 LTE-A 64GB. Install it when the original cell no longer holds charge, swells, or stops accepting a charge cycle entirely.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSM-T900, SM-T905, and TabPRO 12.2 compatibility:\u003c\/strong\u003e\n    These models share the same battery bay dimensions, connector pinout, and BMS handshake protocol. The T9500E cell fits all four variants without modification — the BMS reads cell state identically across the SM-T900 and TabPRO 12.2 platform.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran the T9500E through a full charge and load cycle on an SM-T900. The BMS accepted the charge without error flags, voltage climbed steadily to 4.35V at full charge, and the tablet registered the new cell without a forced reboot.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration after swap:\u003c\/strong\u003e\n    After installation, run one full discharge to automatic shutoff, then charge uninterrupted to 100% without using the tablet. This forces the fuel gauge IC to recalibrate against the new cell's actual capacity curve and clears the percentage drift that almost always appears after a cell replacement.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Galaxy Tab S 10.5 shuts down at 15–25% after a battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe SM-T900 combines a high-brightness 10.5\" display with simultaneous WiFi activity — a combined load that creates a sharp voltage sag near the lower end of the cell's discharge curve. If the fuel gauge IC is still calibrated to the old cell, it misreads the new cell's remaining capacity and triggers a low-voltage cutoff earlier than the actual state of charge warrants. One full discharge-to-shutoff cycle followed by an uninterrupted charge to 100% corrects the IC's reference map. After recalibration, the shutoff point moves back to below 5% where it belongs.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eFast charging unavailable on the SM-T900 after battery replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eSamsung's adaptive fast charge handshake on this tablet requires the charge IC to complete at least one accepted full charge cycle on the new cell before re-enabling elevated charge rates. Immediately after a swap, the tablet may default to standard 5V charging until that first cycle completes. Plug into the original Samsung fast charger, let the tablet charge fully from below 10% without interruption, and fast charge will re-engage on the next session. If it still does not activate, confirm the charger output is 9V\/1.67A or higher — third-party chargers below that threshold will not trigger the protocol.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426047524954,"sku":"BWCS-SMT900SL-1","price":49.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426047557722,"sku":"BWCS-SMT900SL-2","price":57.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426047590490,"sku":"BWCS-SMT900SL-3","price":63.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SMT900SL-1.webp?v=1779930219","url":"https:\/\/batteryweb.com\/products\/samsung-sm-t900-replacement-battery-38v-9500mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
