If you're wondering what models are regarded as eligible devices, you should note it down that the Apple Watch Series 2 in 42mm size which can be the Sports, Nike+, Hermes or even the Apple Watch Edition variant.
Apple Watch users have for years complained of expanded, or swollen, batteries across multiple device generations.
The document also states that "Apple will authorize coverage for eligible devices for three years after the original date of purchase". Apple will service eligible devices free of charge.
Hey, it happens. As it goes, Apple is now dealing with a battery life issue on some of its Apple Watch devices, and is offering free repairs to customers who are experiencing swollen batteries. Apple has nearly always replaced or serviced such devices and generally covers expanded batteries past the 1-year warranty date, regardless of a program such as this.
Apple Stores and Authorized Service Providers are now servicing Apple Watch Series 2 models with swollen batteries or that won't power on. The program does not, however, apply to any Series 1 or Series 3 models, nor does it apply to any 38mm models.
Apple implemented a similar policy regarding those as well. Like most lithium-ion battery packs, the pouches used to power Apple Watch are susceptible to swelling and expanding when punctured, overcharged, overheated or otherwise damaged. Apple has noted that all models of the Apple Watch Series 2 will be a subject to "visual-mechanic" inspection before the inspection takes place. Let us know in the comments.
