Rocky Sand Studio Ltd. offers a free solution for MackBook owners who want to see how “healthy” their laptop’s battery is. The app provides status information in an easy and accessible environment, and best of all, it’s completely free.
Compatible only with MacBooks (mainly because desktops don't run on batteries), Battery Diag helps you access battery details from your menu bar, offering a quick overview of your laptop's most important battery status information.
Version 1.0.1 was released this week with Retina compatibility fixes and other bug fixes. To download Battery Diag, you need a MacBook Air or MacBook Pro running any version of OS X 10.9 (Mavericks) and of course a 64-bit processor.
As we mentioned at the beginning, it is offered completely free of charge and is not a trial version or promotion of any advertising. Reviews on the Mac App Store show that users are generally satisfied with the functionality of the application.
