MacBook Air’s battery details emerge

The MacBook Air wowed us all on Tuesday, and as the time passes, some specific details have begun to reach the Internet. For example, Apple’s claim of 5 hour battery life is much more reasonable than usual. Ars Technica achieved 5 hours with WiFi on and the screen at half-brightness while browsing the web and doing other productivity tasks. Also, the battery is not user replaceable. So you can’t swap out your battery on the fly. Instead, you will have to pay $129 for a new battery and Apple will replace it for you, free of charge. This can be done by mailing it to Apple in Cupertino, CA and wait 5 days, or just bring it in to your local Apple store.

With WiFi on, my MacBook Pro maybe does 2 and a half hours of battery, making the MacBook Air’s battery quite impressive for such a slim machine.
