It also fits the Ellipsis MV7A, QMV7A 8GB, and QMV7B. Swap it in when the original cell no longer holds a charge or the tablet won't power on.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eEllipsis QMV7A and QMV7B compatibility:\u003c\/strong\u003e\n    These models share the same 3.7V single-cell Li-Polymer architecture, identical connector pinout, and the same charge IC handshake — so 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 QMV7A platform. The BMS accepted the charge IC handshake immediately, and the protection circuit tripped correctly at the low-voltage threshold without nuisance cutoffs during display and WiFi load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge reset after installation:\u003c\/strong\u003e\n    After fitting this cell, run the tablet down to automatic shutoff, then charge uninterrupted to 100%. This gives the fuel gauge IC one full reference cycle against the new cell and clears the inaccurate percentage readings that almost always 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  \u003cp class=\"bpw-desc-p\"\u003eThe Ellipsis QMV7A draws a combined load from the display backlight and WiFi radio simultaneously. Under that load, a new Li-Polymer cell can show a steeper voltage drop than the fuel gauge IC expects, because the IC is still calibrated to the old cell's discharge curve. The tablet interprets that voltage drop as a critically low state and triggers a shutdown — even though actual capacity remains. Run one full discharge-to-shutoff cycle followed by an uninterrupted charge to 100% to synchronise the fuel gauge to the new cell's curve.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eFast charging unavailable after swapping the QMV7A battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Ellipsis QMV7A uses a USB-PD negotiation sequence that requires the charge IC to complete at least one accepted charge cycle before the device unlocks higher charge rates. Immediately after a swap, the tablet defaults to standard 5V charging while it validates the new cell. Plug in, let the first charge run from low to 100% without interruption, and fast charge should become available on the next session.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426049392730,"sku":"BWCS-RMV700SL-1","price":28.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426049425498,"sku":"BWCS-RMV700SL-2","price":32.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426049458266,"sku":"BWCS-RMV700SL-3","price":35.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-RMV700SL-1.webp?v=1779930219","url":"https:\/\/batteryweb.com\/products\/verizon-elipsis-qmv7a-7in-replacement-battery-37v-4000mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
