It fits the 8.7-inch 2021 tablet lineup that shares the HQ-3565N cell specification. Install it when the original cell no longer holds charge through a normal day of use.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSM-T220 and SM-T225 series fit:\u003c\/strong\u003e\n    Samsung uses the same 117.40 × 97.00 × 2.80mm cell across the Wi-Fi and LTE variants of the A7 Lite. The connector pinout and BMS handshake protocol are identical across that range, so this 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 cycles on an SM-T225. The BMS accepted the new cell on first connection, reported state-of-charge within a normal range, and thermal readings stayed within Samsung's spec throughout the charge cycle.\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% without using the device. This gives the fuel gauge IC a full reference curve against the new cell and corrects 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 Tab A7 Lite shuts down at 15–25% remaining\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Galaxy Tab A7 Lite drives a backlit 8.7-inch display and a Wi-Fi radio simultaneously during normal use. When both pull current at the same time, the voltage on a degraded — or freshly fitted — cell dips sharply. The BMS reads that dip as a low-voltage cutoff condition and shuts the tablet down before the reported percentage reaches zero. This is a fuel gauge calibration problem, not a cell defect. After one full discharge-to-shutoff and an uninterrupted charge to 100%, the gauge recalibrates and the early shutdowns stop.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eFast charging not available after fitting a new cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eSamsung's adaptive fast charge protocol requires the charge IC to complete one accepted charge handshake with a new cell before it unlocks higher input rates. If the tablet shows only standard charging on the first cycle after a battery swap, that is expected behaviour — not a wiring fault. Charge the device fully once using the original Samsung charger and cable. Fast charge should activate automatically from the second cycle onward.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43425827782746,"sku":"BWCS-SMT220SL-1","price":43.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43425827815514,"sku":"BWCS-SMT220SL-2","price":51.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43425827848282,"sku":"BWCS-SMT220SL-3","price":56.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SMT220SL-1.webp?v=1779929930","url":"https:\/\/batteryweb.com\/products\/samsung-galaxy-tab-a7-lite-replacement-battery-385v-4900mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
