It fits all Venue 11 Pro 7140 variants, including the standard tablet and convertible configurations. The connector, BMS pinout, and physical dimensions match the OEM unit at 248.80 x 79.40 x 5.10mm.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eVenue 11 Pro 7140 compatibility:\u003c\/strong\u003e\n    All Venue 11 Pro 7140 variants share the same battery bay geometry, voltage rail, and EC communication protocol. OEM part numbers HFRC3, TXJ69, and 2H2G4 all map to this same cell configuration, so the fit is consistent across the model range.\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 a Venue 11 Pro 7140 unit. The BMS handshook correctly with the EC on first insertion, charge acceptance was normal from the first cycle, and no fault flags appeared in the battery status register.\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 under normal use — screen on, Wi-Fi active — then charge uninterrupted to 100% without unplugging. This one full cycle resets the fuel gauge IC against the new cell's actual capacity curve 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\"\u003eWhy the Venue 11 Pro 7140 shuts down at 15–25% remaining\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Venue 11 Pro 7140 drives a high-resolution display and maintains simultaneous Wi-Fi, Bluetooth, and background Windows processes. Under that combined load, cell voltage drops faster than the fuel gauge IC predicts — especially when the gauge is still calibrated to an old, degraded cell. The EC reads the voltage cliff as a critical low-battery event and triggers an immediate shutdown to protect the cell, even though the reported percentage still shows charge remaining. After fitting this replacement cell, run one full discharge-to-shutoff and uninterrupted recharge cycle. This forces the gauge IC to map its percentage curve against the new cell's actual discharge profile.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eFast charging unavailable after battery replacement on Venue 11 Pro 7140\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eSome users see the charging indicator revert to standard rate immediately after swapping the battery, even when using the original Dell adapter. The charge IC on a fresh cell starts in a conservative state until it completes one accepted charge cycle and verifies adapter handshake data. Plug in the original Dell 45W or 65W adapter and allow a full charge to 100% without interruption. After that first complete cycle, fast charge negotiation resumes at the normal rate and the slower charging behaviour does not return.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43425866121306,"sku":"BWCS-DEV714SL-1","price":61.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43425866154074,"sku":"BWCS-DEV714SL-2","price":71.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43425866186842,"sku":"BWCS-DEV714SL-3","price":79.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-DEV714SL-1.webp?v=1779930008","url":"https:\/\/batteryweb.com\/products\/dell-venue-11-pro-7140-replacement-battery-74v-5100mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
