A:AnswerThe battery has the ability to be "replaced" just like the other Apple Watches in the sense that you can take it to a store/send it in for "replacement". The Ultra battery replacement costs $99.00 compared to the standard $79.00 for the other models.
Repair for the Ultra (such as glass, case damage, etc) are currently $499.00 compared to $299.00 and $399.00 for the standard models when you don't have AppleCare+
