It fits the Wi-Fi, 4G, and LTE variants. It replaces part number BLT003 using the original connector and dimensions (129.00 x 107.20 x 3.00mm).\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eRealme Pad Mini variant compatibility:\u003c\/strong\u003e\n    The Wi-Fi, 4G, and LTE models all share the same BLT003 cell, connector pinout, and BMS communication protocol — one battery services all three without modification.\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 the Realme Pad Mini platform. The BMS accepted the new cell on first connection and reported state-of-charge within normal parameters after a full calibration cycle.\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, then charge uninterrupted to 100%. The fuel gauge IC calibrates against the old cell's data — one complete cycle resets it against the new cell and clears inaccurate percentage readings.\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 Realme Pad Mini's display and simultaneous Wi-Fi activity create a combined load spike that hits the battery hard in the lower state-of-charge range. At around 3.5V cell voltage, the BMS interprets the voltage sag from that combined draw as a critically low condition and cuts power before the fuel gauge reaches 0%. The fix is a full discharge-to-shutoff cycle followed by a complete uninterrupted charge. After that single calibration cycle, the fuel gauge IC maps the new cell's actual voltage curve and the shutdowns stop.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eFast charging unavailable after fitting the BLT003 replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eRealme's proprietary fast charge protocol requires at least one completed charge handshake cycle before the charge IC trusts a new cell's negotiation data. If fast charging doesn't appear immediately after installation, this is expected behaviour — not a fault with the battery. Plug in using the original Realme adapter, allow one full charge to 100%, and disconnect. On the next charge session the adapter and charge IC should complete the handshake and fast charge will resume.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43425826308186,"sku":"BWCS-OPR105SL-1","price":40.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43425826340954,"sku":"BWCS-OPR105SL-2","price":47.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43425826373722,"sku":"BWCS-OPR105SL-3","price":52.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-OPR105SL-1.webp?v=1779929853","url":"https:\/\/batteryweb.com\/products\/oppo-realme-pad-mini-replacement-battery-387v-6200mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
