It fits models 2761, 2762, A2301, and A2369 among others. Capacity figure is taken directly from the product specification — 28.73Wh total.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eiPad Pro 12.9-inch 2nd Gen compatibility:\u003c\/strong\u003e\n    These models share the same 3.78V cell footprint, connector pinout, and BMS handshake protocol. Swapping between them does not require firmware changes — the charge IC reads cell chemistry directly.\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 2nd gen iPad Pro chassis. The BMS accepted the new cell without faults, and the charge IC communicated state-of-charge normally through the full range.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration after swap:\u003c\/strong\u003e\n    After installation, run one complete discharge to automatic shutoff, then charge uninterrupted to 100%. This gives the fuel gauge IC a known reference range against the new cell and clears inaccurate percentage readings that commonly appear immediately 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\"\u003eiPad Pro 12.9 shutting down at 15–25% remaining\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the display backlight, A10X processor, and active Wi-Fi run simultaneously under load. The combined draw creates a brief voltage sag that the fuel gauge IC reads as a critically low cell. An aged or freshly installed battery without a completed calibration cycle is especially prone to this. Run one full discharge-to-shutoff cycle followed by an uninterrupted charge to 100%. The shutdowns stop once the IC has mapped the actual voltage curve of the new cell.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eFast charging not available after battery replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe iPad Pro 12.9-inch 2nd gen uses USB Power Delivery negotiation via its Lightning port to accept higher charge rates. After a battery swap, the charge IC on the new cell needs one completed accepted charge cycle before it confirms USB-PD compatibility to the OS. Connect with an Apple 18W or higher USB-PD adapter and let the first charge run uninterrupted to 100%. After that cycle, fast charge availability returns to normal and the setting appears correctly in the battery health screen.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43425825652826,"sku":"BWCS-IPA369SL-1","price":306.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43425825685594,"sku":"BWCS-IPA369SL-2","price":366.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43425825718362,"sku":"BWCS-IPA369SL-3","price":411.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-IPA369SL-1.webp?v=1779929837","url":"https:\/\/batteryweb.com\/products\/apple-2761-replacement-battery-378v-7600mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
