Apple Launches Battery Replacement Program for Non-Touch Bar 13-Inch MacBook Pro Models
Apple says that a limited number of these units feature a component that can fail and cause the built-in battery to expand. It is not a safety issue, according to the company, and Apple will replace all eligible batteries.
Customers who want to see if their machines are eligible for a fresh battery should use the serial number checker on the MacBook Pro Battery Replacement page. You can find your serial number by clicking on the Apple logo in the menu bar and selecting "About This Mac." The serial number is located at the bottom of the information window.
Affected customers who are eligible for a new battery will need to visit an Apple Authorized Service Provider, make an appointment at an Apple retail store, or mail their device into an Apple Repair Center after initiating a repair with Apple Support.
Apple suggests customers who are getting a battery replacement back up their machines ahead of time. Apple also says that if the MacBook Pro in question has damage that will impair the replacement of the battery, it must be addressed prior to the battery replacement process.
Any customer who has already paid for a replacement battery can contact Apple Support about a refund.
The battery replacement program covers affected MacBook Pro models for five years after the first retail sale of the unit.
