If you're aware of the AppleCare+ service offered by Apple, you'll know that once your MacBook starts losing its ability to hold a charge, the battery is then replaced by the company. Users not covered by this policy are charged a one-off service fee of $199. However, due to reported battery supply problems experienced by the company, several owners of specific MacBook devices could receive a full replacement of the laptop when submitting a service request. Apple notified its Genius Bar employees and global suppliers that the company has been experiencing a supply issue pertaining to the battery in certain MacBooks, specifically the Early-2012 and Mid-2013 models; and according to a directive obtained by MacRumors, the company has requested that the devices are replaced with similar products. Customers have noticed that instead of receiving a replacement battery, they were offered a refurbished model, and in some cases a brand new 2016 or 2017 MacBook.
