It matches OEM part numbers MLP36100107 and SQU-1408. The cell sits at 122.50 x 98.00 x 3.50mm — same footprint as the factory pack.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eEllipsis 8 and Ellipsis Kids platform fit:\u003c\/strong\u003e\n    The QTAQZ3 board and its Kids LTE variant share the same 3.7V power rail, connector pinout, and BMS handshake requirements. One cell covers the full lineup without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this battery through charge and discharge on the QTAQZ3 board. The BMS accepted the cell without fault codes, and the charge IC stepped through CC\/CV stages cleanly at both 5V standard and USB-PD input.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration after swap:\u003c\/strong\u003e\n    After installing this cell, run the tablet down to automatic shutoff, then charge uninterrupted to 100% without unplugging. The fuel gauge IC is calibrated against the old cell — this single full cycle resets it against the new one and clears the inaccurate percentage readings that appear immediately post-installation.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eEllipsis 8 shutting down at 15–25% remaining\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eWhen the display and WiFi radio draw current simultaneously, the combined load causes a sharp voltage sag near the lower end of the discharge curve. If the BMS reads the sag as a hard undervoltage event, it trips and shuts the tablet down before the percentage counter reaches zero. This happens with degraded original cells but can also occur temporarily with a new replacement before the fuel gauge recalibrates. Run one full discharge-to-shutoff cycle followed by an uninterrupted charge to 100% — after that, the gauge reads the actual voltage floor of the new cell, and early shutdowns stop.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eFast charging not available after battery swap on the Ellipsis 8\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eUSB-PD negotiation and proprietary fast-charge protocols require the charge IC to complete at least one accepted full charge cycle before the tablet enables higher-wattage input. Immediately after a battery swap, the device often defaults to standard 5V\/1A charging until that handshake is established. Plug into the original Verizon charger — not a generic cable — and let the tablet charge fully to 100% without interruption. After that first complete cycle, fast charging resumes at the normal rate.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43425950072922,"sku":"BWCS-RQZ300SL-1","price":36.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43425950105690,"sku":"BWCS-RQZ300SL-2","price":42.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43425950138458,"sku":"BWCS-RQZ300SL-3","price":46.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-RQZ300SL-1.webp?v=1779930026","url":"https:\/\/batteryweb.com\/products\/verizon-ellipsis-8-replacement-battery-37v-4000mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
