It fits the 10.1-inch Android hybrid tablet directly. Voltage and capacity match the original specification exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eTF701T and K00C compatibility:\u003c\/strong\u003e\n    Both model designations refer to the same hardware revision. They share the same connector pinout, the same BMS communication line, and the same charge IC on the motherboard. One battery covers both.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through full charge and discharge cycles on the TF701T motherboard. The BMS handshake completed on first connection, charge IC accepted the cell without fault codes, and the protection circuit tripped correctly at low-voltage cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration after swap:\u003c\/strong\u003e\n    The TF701T uses a fuel gauge IC that tracks charge state against the old cell's capacity curve. After fitting this battery, run one full discharge to automatic shutoff, then charge uninterrupted to 100%. This resets the IC against the new cell and clears the inaccurate percentage reading that appears post-installation.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTF701T shutting down at 15–25% battery remaining\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe TF701T draws heaviest current when the display backlight is at full brightness and WiFi is actively transferring data. At around 15–25% state of charge, cell voltage drops fast under that combined load. The BMS reads this voltage cliff as a low-voltage condition and triggers an immediate shutdown before the percentage display catches up. Fitting a fresh cell reduces internal resistance, which flattens that voltage sag — but the fuel gauge IC still needs one full calibration cycle to report the correct cutoff point. Run the recalibration discharge described above, and the premature shutdowns stop.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping or stuck after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eAfter a cell swap, the fuel gauge IC on the TF701T is still calibrated to the capacity curve of the old, degraded battery. It will report incorrect percentages — often jumping from 40% to 10%, or locking at a fixed number while the tablet continues to run. This is not a fault with the replacement cell. Force the IC to relearn by discharging the tablet completely until it shuts off on its own, then plug in and charge to 100% without interruption. One full cycle is enough to recalibrate the gauge against the new 8150mAh cell.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426052898906,"sku":"BWCS-AUF701SL-1","price":40.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426052931674,"sku":"BWCS-AUF701SL-2","price":47.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426052964442,"sku":"BWCS-AUF701SL-3","price":52.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-AUF701SL-1.webp?v=1779930307","url":"https:\/\/batteryweb.com\/products\/asus-transformer-tf701t-replacement-battery-38v-8150mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
