About this replacement
Apple iPad Pro 11 2018 / 3rd Gen — 3.8V Li-Polymer Replacement Battery (A2042, 020-02507)
This 3.8V, 7700mAh (29.26Wh) lithium-polymer battery replaces the internal cell in the Apple iPad Pro 11-inch (2018 and 3rd Generation, including models A1980 and A2013). It fits when the original battery no longer holds a charge or the tablet shuts down unexpectedly at moderate charge levels. Capacity matches OEM specification — no reduction to fit a third-party form factor.
- iPad Pro 11 2018 and 3rd Gen compatibility: These models share identical battery dimensions (187.50 × 145.35 × 3.15mm), the same 3.8V cell architecture, and an identical connector pinout — which is why A1980, A2013, and the additional 3rd Gen variants all run from the same replacement cell.
- Bench tested on actual hardware: We cycled this battery through full charge and discharge on an iPad Pro 11 unit. The charge IC accepted the cell without flag, BMS handshake completed normally, and the tablet reached full charge without thermal error or charge-stage interruption.
- Fuel gauge recalibration after swap: After installation, run the tablet down to automatic shutoff, then charge uninterrupted to 100%. This resets the fuel gauge IC against the new cell's actual capacity and clears the inaccurate percentage readout that typically appears in the first few sessions after a battery swap.
iPad Pro 11 shutting down at 15–25% remaining after battery replacement
This happens because the fuel gauge IC is still calibrated to the old cell's voltage curve. When the new cell's voltage drops into the 3.5–3.6V range under combined display and WiFi load, the IC interprets it as a deeper discharge than it actually is and triggers a protective shutdown. The tablet still has usable charge — the gauge just doesn't know it yet. One full discharge-to-shutoff followed by an uninterrupted charge to 100% resets the reference point and resolves the premature cutoff.
Fast charging not available after battery swap on iPad Pro 11
USB-PD fast charging on the iPad Pro 11 requires the charge IC to complete at least one accepted charge cycle before the device negotiates higher wattage from a USB-PD adapter. Immediately after a swap, the tablet may draw at standard 5V/2A rather than the 18W+ rate. Run one complete charge from low battery to 100% using the original Apple USB-C adapter. After that cycle, USB-PD negotiation resumes normally and fast charging becomes available again.
