It fits the original cell slot directly, using the same OEM part number EB-BT725ABU. If your Tab S5e no longer holds a charge or powers on reliably, this replaces the degraded cell.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSM-T720 and SM-T725 variant coverage:\u003c\/strong\u003e\n    Both the Wi-Fi (SM-T720) and LTE (SM-T725) Tab S5e models share the same battery connector, voltage rail, and BMS handshake protocol — this cell works across the full S5e lineup without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through the Tab S5e charge IC and confirmed BMS communication, thermal sensor registration, and charge acceptance at the correct 4.40V upper cutoff. No false full-charge flags on either the Wi-Fi or LTE board.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration after swap:\u003c\/strong\u003e\n    The Tab S5e uses a dedicated fuel gauge IC that calibrates to the previous cell's internal resistance profile. After installation, run one full discharge to automatic shutoff, then charge uninterrupted to 100%. This resets the IC against the new cell and eliminates inaccurate percentage readings.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Tab S5e shuts down at 15–25% after a battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe fuel gauge IC on the SM-T720 board was calibrated to the resistance curve of the old, degraded cell. A new cell has lower internal resistance, so the IC underestimates remaining capacity at moderate load. When the display backlight and Wi-Fi radio draw current together, the reported voltage drops faster than the gauge expects, triggering a low-voltage shutdown before the cell is genuinely depleted. One full discharge-to-shutoff cycle followed by an uninterrupted charge to 100% realigns the IC to the new cell's actual curve.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eFast charging not available on the Tab S5e after battery replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eSamsung's Adaptive Fast Charging on the Tab S5e requires the charge IC to complete at least one full accepted charge cycle before it unlocks higher current delivery. Immediately after a swap, the tablet defaults to standard 5V charging while the IC verifies the new cell accepts voltage correctly. This is a protective hold, not a fault. Charge the tablet fully once using the original Samsung charger and cable — fast charging typically re-enables on the next charge session.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43425841643610,"sku":"BWCS-SMT720SL-1","price":39.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43425841676378,"sku":"BWCS-SMT720SL-2","price":45.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43425841709146,"sku":"BWCS-SMT720SL-3","price":50.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SMT720SL-1.webp?v=1779929976","url":"https:\/\/batteryweb.com\/products\/samsung-galaxy-tab-s5e-replacement-battery-385v-6800mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
