2>Installation Notes For Fast Turnaround
Plan a 15–25 minute bench time using a P5 pentalobe driver for the bottom case and a T5 torx for the battery screws. Always shut down the MacBook Air, disconnect the battery from the logic board before any other step, and avoid kinking or puncturing the cells during removal and placement. The A1406 is a screw‑in assembly, so no adhesive strips are required.
After installation, perform a simple calibration for consistent fuel‑gauge. Charge to 100%, keep it connected for an additional 30–60 minutes, then run on battery to around 5–7% before charging back to full. Keep firmware and macOS up to date to ensure optimal charge control and sleep behavior.
