It replaces OEM part numbers KT.0010H.003, PR-329083(1ICP4\/90\/84), and PR-329083. The cell matches the original dimensions at 84.30 x 89.40 x 3.00mm, so it seats correctly in the chassis without modification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eB1-770 platform fit:\u003c\/strong\u003e\n    The B1-770 uses a single-cell Li-Polymer pack with a proprietary connector tied to the tablet's charge IC. This replacement matches that connector pinout and communicates correctly with the onboard BMS — no voltage mismatch, no charge rejection on first plug-in.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge and discharge on the B1-770 platform. The BMS accepted the cell immediately, balanced correctly to 4.2V at full charge, and enforced low-voltage cutoff at the expected threshold without triggering false shutdowns.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge reset after swap:\u003c\/strong\u003e\n    After installation, run the tablet down to automatic shutoff, then charge uninterrupted to 100% before use. This single full cycle resets the fuel gauge IC calibration against the new cell and clears the inaccurate percentage readings that commonly appear after a battery 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 after battery replacement\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe B1-770 fuel gauge IC stores a charge map calibrated to the old cell's discharge curve. A new cell has a different internal resistance profile, so the IC miscalculates remaining capacity under load. When the display and WiFi draw current simultaneously, voltage sags briefly, and the IC interprets this as a critically low state. One full discharge-to-shutoff cycle followed by an uninterrupted charge to 4.2V corrects the map and stops the early cutoffs.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eFast charging unavailable on B1-770 after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe B1-770 charge IC gates fast-charge negotiation until it completes one accepted charge cycle with the new cell. On the first charge after a swap, the charger typically falls back to standard rate. This is the IC confirming the cell's impedance before allowing higher current. Charge fully once at standard rate, then disconnect and reconnect — fast charge protocol resumes on the second cycle.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43425988837466,"sku":"BWCS-ACW770SL-1","price":27.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43425988870234,"sku":"BWCS-ACW770SL-2","price":31.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43425988903002,"sku":"BWCS-ACW770SL-3","price":34.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ACW770SL-1.webp?v=1779930008","url":"https:\/\/batteryweb.com\/products\/acer-iconia-one-7-b1-770-replacement-battery-37v-2700mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
