About this replacement
Apple iPad Pro 12.9-inch 2nd Gen — 3.78V Li-Polymer Replacement Battery (A2369)
This 3.78V, 7600mAh lithium-polymer battery replaces the original cell in the Apple iPad Pro 12.9-inch (2nd generation). It fits models 2761, 2762, A2301, and A2369 among others. Capacity figure is taken directly from the product specification — 28.73Wh total.
- iPad Pro 12.9-inch 2nd Gen compatibility: 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.
- Bench tested on actual hardware: 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.
- Fuel gauge recalibration after swap: 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.
iPad Pro 12.9 shutting down at 15–25% remaining
This 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.
Fast charging not available after battery replacement
The 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.
