It fits the 7-inch Android tablet directly, restoring power to the display, processor, and radios. Dimensions are 94.55 × 85.70 × 3.20mm — confirm clearance before installation if your unit has any aftermarket internals.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eB1-750 fit confirmation:\u003c\/strong\u003e\n    The B1-750 uses a single-cell Li-Polymer pack rated at 3.8V nominal. OEM part numbers AP14E4K, KT.0010G.007, KT.00104.001, AP14E8K, and KT00104001 all cross-reference to this cell configuration and connector pinout.\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 B1-750 board. The charge IC accepted the new cell without fault flags, and the BMS communicated state-of-charge data correctly to the OS after a calibration 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 — do not manually power it off — then charge uninterrupted to 100%. This gives the fuel gauge IC a full-range reference against the new cell and clears 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\"\u003eTablet shutting down at 15–25% remaining on the B1-750\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the display backlight and active WiFi pull current simultaneously, causing a brief voltage sag at the cell terminals. If the fuel gauge IC was calibrated to an aged cell, it maps this sag to a much lower state-of-charge than the new cell actually holds. The BMS then triggers a protection cutoff before the cell is genuinely depleted. One full discharge-to-shutoff cycle followed by an uninterrupted charge to 100% resets the reference table and eliminates these premature shutdowns.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eB1-750 showing wrong battery percentage after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe fuel gauge IC on the B1-750 board stores a charge map built around the original cell's internal resistance and capacity curve. A new cell has different characteristics, so the reported percentage drifts — often reading 80% when the cell is nearly full, or jumping from 40% to 10% with no warning. This is a calibration issue, not a faulty battery. Force one complete cycle: discharge to automatic shutoff, then charge uninterrupted to 100% with the screen off. After that single cycle the gauge tracks within a few percent.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43425958494298,"sku":"BWCS-ACB750SL-1","price":28.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43425958527066,"sku":"BWCS-ACB750SL-2","price":32.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43425958559834,"sku":"BWCS-ACB750SL-3","price":35.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ACB750SL-1.webp?v=1779930008","url":"https:\/\/batteryweb.com\/products\/acer-iconia-one-7-b1-750-replacement-battery-38v-3400mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
