About this replacement
Apple iPad Pro 11-inch (2024) & 12.9-inch A2836 Series — 3.84V Li-Polymer Replacement Battery (0098S)
This is a 3.84V, 8150mAh (31.3Wh) Li-Polymer battery for the Apple iPad Pro 11-inch (2024) and related models A2836, A2837, and A3006. It replaces the original cell when capacity has dropped, charge cycles are exhausted, or the tablet no longer holds a usable charge. Fit models share the same connector pinout, cell dimensions, and BMS communication protocol.
- A2836 / A2837 / A3006 platform fit: These three model numbers use the same physical cell size, the same four-pin flex connector, and the same SMBus handshake to the charge IC. Swapping between them does not require firmware changes or connector adapters.
- Bench tested on actual hardware: We seated this cell in an A2836 chassis and cycled it through the charge IC. The BMS accepted charge negotiation cleanly, cell voltage rose at the expected C-rate, and the charge IC transitioned to trickle at 4.35V without fault flags.
- Fuel gauge recalibration after swap: After installation, run the tablet down to automatic shutoff, then charge uninterrupted to 100% without using the device. This single full cycle lets the fuel gauge IC recalibrate against the new cell and clears the inaccurate percentage readings that almost always appear immediately after a battery swap.
iPad Pro shutting down at 15–25% remaining after battery replacement
This happens because the fuel gauge IC still holds voltage-to-capacity mapping data from the old, degraded cell. The new cell has a steeper voltage curve in the lower charge range, so the IC reads a voltage cliff as a shutdown threshold before the cell is actually empty. The tablet cuts out at what it thinks is a safe floor — but that floor is wrong. One full discharge-to-shutoff cycle followed by an uninterrupted charge to 100% rewrites the IC's internal map. After that cycle, the shutdown behaviour resolves and the remaining percentage tracks accurately down to the real low-voltage cutoff near 3.0V per cell.
Fast charging not available after battery swap
USB-PD fast charging requires a completed charge handshake between the charger, the iPad's charge IC, and the new cell. On a freshly installed cell, the charge IC may default to a conservative 5W profile until it has run one full accepted charge cycle. This is a protection behaviour, not a fault. Plug in Apple's 20W or higher USB-C adapter and allow one full charge to 100% without interruption. After that cycle completes, the charge IC re-enables the higher-wattage PD profile.
