Easy battery replacement

Mi Problema

My MacBook battery began to fail and expanded to the point of temporarily deforming the aluminum near the trackpad.

Mi Solución

Using the iFixit Pro Tech Toolkit, I followed the instructions in the step-by-step guide. The battery charged in a few hours and proceeded to work fine.

Mi Consejo

In the event that the battery swells, remove the screws from the case closest to the failing section of the battery. Use a flat tool to carefully help the battery case out of the machine if the swelling is enough to deform the case.
