Apple has launched a battery replacement program for 13-inch MacBook Pros without Touch Barmanufactured between October 2016 and October 2017. Apple said that the flaw in the affected devices could cause their built-in batteries to expand.
Since not all 13-inch Pros without Touch Bar are affected (other and older models aren’t prone to the same component failure) you’ll first have to make sure you’re covered under the program. Simply go to the program page and look up your serial number, which you can find in About this Mac (click the Apple logo on the top menu), under your laptop or on its box.
If you’re eligible for a replacement, you’ll have to find an Apple Store or an Apple Authorized Service Provider, but you can also mail your laptop to a repair center.
