It fits the standard Platinum 7\" form factor. The cell matches OEM part numbers MLP4063112, 800-10067, and MP5461110.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eLeapPad Platinum and XDi Ultra compatibility:\u003c\/strong\u003e\n    These models share the same 3.7V single-cell Li-Polymer architecture, connector pinout, and BMS handshake logic. The same 112.10 × 62.20 × 4.60mm cell footprint runs across this entire platform revision.\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 LeapPad Platinum unit. The BMS accepted the new cell without error flags, held the charge rail steady under combined display and WiFi load, and reported state of charge without cutoff anomalies.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration after swap:\u003c\/strong\u003e\n    After installing this battery, run one full discharge to automatic shutoff, then charge uninterrupted to 100%. The LeapPad's fuel gauge IC calibrated against the old cell — this single cycle resets it against the new one and clears 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\"\u003eLeapPad Platinum shutting down at 15–25% remaining\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eWhen the display, WiFi radio, and active app load all draw simultaneously, the cell voltage drops sharply at low state of charge. The BMS reads this voltage cliff as a critically low threshold and triggers an emergency cutoff before the percentage counter reaches zero. This is a fuel gauge calibration mismatch, not a fault in the replacement cell. Run one full discharge-to-shutoff cycle followed by an uninterrupted charge to 100% — after one complete cycle the fuel gauge recalibrates and the early shutdown stops.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLeapPad percentage dropping faster than expected from 100%\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe LeapPad's fuel gauge IC stored capacity data from the old, degraded cell. Against a new 3200mAh cell it reads drain rate incorrectly, causing the percentage to fall faster in the first quarter of charge than it should. This is not a defect in the replacement battery — it is a calibration drift issue. One full discharge to automatic shutoff followed by a continuous charge to 100% forces the fuel gauge to relearn the new cell's capacity curve and corrects the drop rate.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43425845018714,"sku":"BWCS-LFT112SL-1","price":28.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43425845051482,"sku":"BWCS-LFT112SL-2","price":32.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43425845084250,"sku":"BWCS-LFT112SL-3","price":35.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-LFT112SL-1.webp?v=1779929951","url":"https:\/\/batteryweb.com\/products\/leapfrog-leappad-platinum-kids-learning-replacement-battery-37v-3200mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
