Apple Exchanging Some 2012 and Early 2013 MacBook Pros Needing Battery Service With Newer Models

After hundreds of charging cycles, a MacBook Pro’s battery begins to lose its ability to hold a charge and should be replaced. Apple offers battery service free of charge with AppleCare+ coverage, or it charges an out-of-warranty fee of $199 in the United States, £199 in the UK, or $259 in Canada.

Due to a severe constraint of top case assemblies with glued-in batteries, however, Apple has informed its Genius Bar employees and Apple Authorized Service Providers it is currently unable to service the batteries of 15-inch MacBook Pro with Retina display models released in Mid 2012 and Early 2013.
