Introduction

This guide contains instructions for using the old-style iFixit adhesive remover with separate bottle and syringe, which is no longer sold. For the updated version, click here.

Use this guide to safely remove the glued-in battery from your MacBook Pro with the help of an iFixit battery replacement kit. The adhesive remover in your kit will dissolve the adhesive securing the battery, allowing you to remove it with ease.

iFixit adhesive remover is highly flammable. Perform this procedure in a well-ventilated area. Do not smoke or work near an open flame during this procedure.

For your safety, drain your MacBook Pro's battery before you begin this procedure. A charged lithium-ion battery can create a dangerous and uncontrollable fire if accidentally punctured.

Note: The solvent used to dissolve the battery adhesive will damage your speakers if it comes in contact with the plastic speaker enclosures. This guide instructs you to remove the speakers before proceeding to the battery.
