Replacement Battery for iPad Pro 12.9 2021

This KingSener A2387 unit replaces the original battery in the 12.9 inch iPad Pro 5th Generation. It matches part numbers A2387, A2378, A2379, A2461 and A2462.

Installation Notes

Fitting this battery requires opening the sealed iPad chassis, disconnecting the original pack and connecting the replacement flex cable. Adhesive strips must be removed and reapplied carefully to avoid screen pressure marks. Common issues include torn ribbon cables, misaligned connectors and residual adhesive causing uneven seating. Professional fitting is strongly advised.

Sustained Use Behaviour

Under continuous load the 40.33WH cell maintains a steady 3.82V output until the protection circuit triggers a controlled shutdown. The lithium-ion chemistry resists voltage sag during extended video playback or compile workloads. Capacity retention follows standard Li-ion ageing curves over repeated full cycles.
