Apple's iPad Battery Replacement Program Forgoes New Battery, Replaces iPad
Several MacRumors readers have noticed that Apple has posted information on its iPad Battery Replacement Service, which allows users to receive a replacement should their device's battery no longer hold a charge. The service will cost $99 plus an additional $6.95 shipping and applicable taxes.
"iPad Battery Replacement Service" is a bit of a misnomer, however, as instead of swapping a new battery into a customer's existing iPad, Apple will simply send the customer a new iPad.
You will receive a replacement iPad that will not contain any of your personal data. Before you submit your iPad for service, it is important to sync your iPad with iTunes to back up your contacts, calendars, email account settings, bookmarks, apps, etc. Apple is not responsible for the loss of information when servicing your iPad.The device exchange is estimated by Apple to require approximately one week to complete and may be arranged through Apple's retail stores, Apple technical support, or Apple Authorized Service Providers.
Devices that have been damaged or had unauthorized service or modifications performed on them will not be eligible for the program.
