Parts and supplies
A new battery assembly matched to the exact model and connector. Use the specified replacement adhesives and protective materials.
Compare the exact model and part number before installation. Confirm all required screws, adhesive, tape, foam and fixtures in the complete procedure.
Exact-model documentationBefore you begin
Choose Apple menu → About This Mac and confirm the model, chip and screen size. For Intel 2020 MacBook Pro, also match the two-port or four-port version. A similar enclosure does not establish parts compatibility.
Battery and workspace precautions
Follow the discharge instruction in stage 1 before opening. A swollen, punctured, dented or unusually hot battery needs specialist handling. Do not bend, heat or force it. Protect your eyes, prevent accidental startup and disconnect power before adjusting any internal connection.
Keep the battery attached to its tray. If an adhesive strip cannot be recovered, stop and follow the manual’s alternative service instructions; do not force the battery out.
