MacBook Pro 2012 Battery Replacement
Replacing a MacBook pro-2012 battery depends a bit on the model you're using. Some MacBook Pro models have a special download so you may have a cover to replace your MacBook Pro battery. If you purchased AppleCare and your computer is still covered, you may be able to replace the battery under warranty. If your computer is out of warranty or is downloading, you still have options. You can always take your MacBook to an Apple-certified technician or computer repair facility.
