Now it has a brand new battery, 16 GB RAM and a 480 GB Solid State Drive (SSD) instead. When it came to me it was equipped with the original factory battery, 4 GB RAM, and a dead 500 GB spinning hard drive.
I’ve been rehabbing a 13-inch MacBook Pro (Mid-2012) that works with macOS 10.15 Catalina and it runs all the software I need to do my work on. This tutorial covers the process for replacing the batteries in those older Mac laptops. MacBook Airs, Retina display-equipped MacBook Pros, and the newer, albeit discontinued MacBooks all have tightly integrated batteries that are glued in, making their removal and replacement very time-consuming and difficult. Older MacBook Pro models, like 13-inch and 15-inch MacBook Pros that predate the Retina display, are very easy to work on. This tutorial will step you through the process of figuring out if your MacBook Pro needs its battery replaced, and if so, how to replace it.
Fortunately many older MacBook Pros have batteries that can be replaced with very little trouble. Over time, their charge capacity diminishes because they wear out. The batteries in Mac laptops are consumable items.
