iFixIt has introduced battery fix kits for the MacBook Prow with Retina Display. In 2012 Apple introduced its sleek, non-upgradable laptop with a battery stubbornly glued to the frame.
iFixIt has been working on a do-it-yourself repair solution for folks who want to replace the battery in their MacBook Pro Retina for a long time. The new “glue-busting” battery kits reportedly have all the tools and instructions you need to replace your own battery. Pricing ranges from $89.95 to $119.95, depending on your MacBook Pro model.
