It fits into the original cell bay without modification. Dimensions are 90.45 × 90.71 × 3.51 mm — check these against your existing cell before ordering.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eV400 and V410 compatibility:\u003c\/strong\u003e\n    Both variants run the same 3.8V power rail and use an identical connector and BMS handshake, so one cell covers both board revisions. The BL-T12 part number applies to the full production run of the LG Pad 7.0 lineup.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell on a V400 board. The BMS accepted the charge profile on the first cycle, current draw stayed within spec at full-display brightness, and no protection trips occurred during a full discharge pass.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge reset after installation:\u003c\/strong\u003e\n    After fitting this battery, run the tablet down to automatic shutoff, then charge uninterrupted to 100%. This gives the fuel gauge IC a reference point against the new cell and corrects the inaccurate percentage readings that commonly appear 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\"\u003eLG Pad 7.0 shutting down at 15–25% remaining after battery replacement\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the fuel gauge IC is still calibrated to the old cell's voltage curve. The new cell has a slightly different voltage-versus-capacity slope, so the system hits its low-voltage cutoff threshold earlier than the percentage display suggests. Under combined display and WiFi load, the voltage sag is enough to trigger an emergency shutdown. One full discharge-to-cutoff cycle followed by an uninterrupted charge to 100% realigns the fuel gauge and eliminates the premature shutdown.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eFast charging not available after fitting a new BL-T12\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe LG Pad 7.0's charge IC uses a handshake with the battery's BMS before enabling higher charge rates. On a fresh cell, this negotiation sometimes fails on the first cycle because the BMS has not yet established a charge history. Connect the tablet to the original LG charger and allow one complete charge from under 10% to 100% without interrupting it. After that cycle completes, fast charging typically becomes available and stays available on subsequent cycles.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426030944346,"sku":"BWCS-BLV400SL-1","price":29.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426030977114,"sku":"BWCS-BLV400SL-2","price":33.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426031009882,"sku":"BWCS-BLV400SL-3","price":36.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BLV400SL-1.webp?v=1779930196","url":"https:\/\/batteryweb.com\/products\/lg-pad-70-replacement-battery-38v-4000mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
