According to Apple, the potential problem is present in the 13-inch version of the MacBook Pro. Apple will cover machines under this program for the first five years after the retail sale of the unit.
The tech giant is reportedly already offering the opportunity for a refund to any MacBook Pro owners who already got their battery replaced and paid the $129 fee typically charged for the service. It seems some units are prone to battery expansions if a certain component fails.
Apple noted, that the "your 13-inch MacBook Pro will be examined prior to any service to verify that it is eligible for this program and in working order". It claims that it is not a safety issue, but that it will replace eligible batteries free of charge. To check if your MacBook Pro is eligible for this, you will need to enter in your MacBook Pro's serial number on Apple's support page and hit submit. The company posted a page on its website where customers can check if their laptop is affected and begin the battery exchange process. "Service may take 3-5 days". Well, such replacements are in the rage and so is the Apple.
Apple, however, will not extend the standard warranty coverage of the devices.
