It fits the tablet unit of the T100TAL hybrid — the screen-and-board half that detaches from the keyboard dock. Voltage and connector match the original spec exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eT100TAL series fitment:\u003c\/strong\u003e\n    The T100TAL, T100TAL-DK008P, T100TAL-1K, and Pad Transformer Book T100TAL all use the same 3.85V battery bay, BMS connector pinout, and charge IC handshake. One cell fits the full range.\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 T100TAL platform. The BMS accepted the new cell without fault codes, and the charge IC completed a full cycle without thermal cutoff or negotiation failure.\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 — do not force power-off — then charge uninterrupted to 100%. This gives the fuel gauge IC a full reference cycle against the new cell and clears inaccurate percentage readings that appear straight after installation.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the T100TAL shuts down at 15–25% remaining\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe T100TAL combines display, SoC, and Wi-Fi on a single power rail drawn from this battery. Under combined load — screen at full brightness plus active Wi-Fi — current draw spikes and battery voltage sags below the BMS cutoff threshold before the percentage counter reaches zero. The fuel gauge IC reads state-of-charge from a model calibrated to the old cell, so the reported percentage is already off. One full discharge-to-shutoff and uninterrupted recharge cycle resets that model against the new cell and typically pushes the shutdown point back below 5%.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eFast charging not available after battery replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe T100TAL's charge IC uses a handshake protocol to confirm battery state before enabling higher charge rates. On a freshly installed cell with no charge history, the IC defaults to a conservative rate until it completes one accepted full cycle. This is not a fault with the battery or the charger. Use the original Asus adapter, let the first charge run to 100% without interruption, and fast-charge capability will be available from the second cycle onward.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43425876017242,"sku":"BWCS-AUT110SL-1","price":50.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43425876050010,"sku":"BWCS-AUT110SL-2","price":58.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43425876082778,"sku":"BWCS-AUT110SL-3","price":65.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-AUT110SL-1.webp?v=1779930008","url":"https:\/\/batteryweb.com\/products\/asus-transformer-book-t100tal-replacement-battery-385v-8000mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
