Apple Laptop Battery A2289 Original

This battery is designed as a replacement for the Apple MacBook Pro 13″ (2020) model A2289 / EMC 3456, closely matching the original Apple specification of approximately 58.2 Wh at 11.41 V. It provides a reliable way to restore battery life and unplugged runtime when the original battery has declined in capacity or is no longer holding a full charge.

The form factor, connector, and cell arrangement are made to align with the original A2289 battery layout, enabling a direct swap without modifications. Built with modern Li‑ion / Li‑polymer cells, and outfitted with built‑in safety circuits to prevent overcharging, overdischarging, excessive current, or overheating, this replacement aims to deliver safe, stable performance.

Installing this battery requires opening the MacBook’s back cover, disconnecting the legacy battery cable, and securing the new pack. After installation, it is recommended to charge it fully, then discharge to ~20%, and charge again to calibrate the battery meter and optimize performance. With a healthy battery, you should regain a significant portion of your original unplugged usage time and avoid unexpected shutdowns or battery warnings.
