It fits the Mi Pad 2, GD4250, and A2015716 variants. This replaces a degraded original cell that can no longer hold adequate charge for everyday tablet use.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMi Pad 2 variant compatibility:\u003c\/strong\u003e\n    The GD4250 and A2015716 share the same battery bay dimensions, connector pinout, and BMS communication protocol as the standard Mi Pad 2 — one cell works across all three.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran the BM61 through charge and discharge cycles on the Mi Pad 2. The BMS accepted the cell without fault codes, and the charge IC stepped through CC\/CV phases correctly at both standard and fast-charge rates.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration after installation:\u003c\/strong\u003e\n    After fitting this battery, run one full discharge to automatic shutoff, then charge uninterrupted to 100% without using the tablet. This gives the fuel gauge IC a clean reference point against the new cell and corrects the inaccurate percentage readings that appear immediately 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\"\u003eMi Pad 2 shutting down between 15–25% remaining\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the display backlight and Wi-Fi radio draw current simultaneously, pulling the cell voltage down faster than the fuel gauge expects. The system reads the voltage drop as a near-empty cell and triggers a protective shutdown before the gauge hits 0%. The fix is a full recalibration cycle — discharge to auto-shutoff, then charge to 100% uninterrupted. After one full cycle, the fuel gauge maps the new cell's voltage curve and the early shutdowns stop.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eFast charging unavailable after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Mi Pad 2 charge IC re-negotiates fast-charge protocol on the first accepted charge cycle after a new cell is installed. If you plug in immediately after the swap and the tablet shows only standard charging, that is expected behaviour — not a fault. Complete one full charge cycle to 100% without interruption. On the next charge session, fast charging re-enables automatically once the IC confirms the cell is stable above 3.85V.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43425872150618,"sku":"BWCS-MUM102SL-1","price":37.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43425872183386,"sku":"BWCS-MUM102SL-2","price":43.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43425872216154,"sku":"BWCS-MUM102SL-3","price":47.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MUM102SL-1.webp?v=1779930025","url":"https:\/\/batteryweb.com\/products\/xiaomi-mi-pad-2-replacement-battery-38v-6000mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
