OEM quality MacBook Battery A2389 specifications
OEM quality MacBook Battery A2389 delivers the same runtime, charge behavior, and safety features you expect from the original pack. The pack uses lithium‑polymer cells in a 3S1P configuration with a nominal voltage of 11.41 v and a typical energy of 58.2 wh, providing balanced capacity without stressing the charge circuitry. An integrated fuel‑gauge controller communicates correctly with macOS battery health management, so you get accurate percentage, cycle count and temperature readings.
OEM grade protection is built in with over‑charge, over‑discharge, over‑current, short‑circuit, and thermal safeguards. The cycle endurance is rated for 800+ full charge cycles to 80% health when used within normal temperature and charging limits. The assembly ships with preinstalled adhesive strips and a board‑mounted flex connector for a clean drop‑in during service. Compliance includes UN38.3, CE, and RoHS, and each unit is ESD packed and lot‑traceable for workshop inventory control.
Reliable performance for repair and refurbishment
You can use MacBook Battery A2389 to resolve rapid drain, swelling, unexpected shutdown, or high cycle count devices that still have strong resale potential. Capacity and impedance are matched across cells to keep peak load stability during compile, video export, virtualization, and other bursty workloads that trigger power draw spikes. Standby behavior mirrors the original, reducing wake drains and keeping sleep current predictable for long bench tests.
Every batch is tested for open‑circuit voltage, internal, and smart data integrity before packing, which simplifies quality checks when you receive goods. Shelf life remains stable when stored at 40–60% state of charge in a cool, dry space, and barcode labels help you rotate stock in high‑volume environments. The pack works with standard macOS diagnostics, so you can validate installation with Apple Diagnostics or third‑party tools and document results for customers or warranty records. The battery is covered with a 1-year product warranty. The warranty does not cover man-made damage or wear and tear.
Installation notes and handling for MacBook Battery A2389
You should power down, disconnect from mains, and discharge existing battery to around 20–30% before removal to reduce risk on the bench. You can access the connector first, release speaker assemblies if required, and then pull the adhesive tabs slowly and parallel to the deck to avoid twisting cells; a small amount of isopropyl alcohol helps if any strip snaps. You should avoid prying under cells with metal tools, and you should never fold, crease, or heat the pack during extraction.
You can seat the new pack without stress on the flex, connect the board last, and torque screws to factory feel prevent chassis resonance. You should perform a calibration cycle after installation by charging to 100%, resting for two hours, then discharging to 5–10% and charging back to full to align the fuel‑gauge. Operating range is 0–35 °c and storage is −20–45 °c, and you should keep the unit away from puncture, moisture, and conductive debris throughout the service process.
