MacBook Pro Unibody Battery Replacement

My Problem

The issue was that after nearly five years of continuous use, the MacBook's lithium battery was failing and the ominous "Replace Soon" label began to appear under the battery icon.

My Fix

At first, the original battery sent didn't work out as well as expected. However, iFixit's support team quickly remedied the situation with issuing a new replacement through the same fast FedEx channel as the original one. And, the second repair was just as fast as before.

My Advice

Batteries seem to be funny things and therefore, I think it is important to thoroughly test the battery that you received to make sure it is performing optimally. The repair itself is a piece of cake, just follow the guide on the website.
