Battery Guard

Battery Guard tells you how long your battery will last! It is a fully featured, enhanced replacement for the battery tray icon that comes with your Mac.

Battery Guard shows the time left on your battery right next to its icon! If you'd rather show the percent charge, you can see that too.

Clicking on the icon opens a panel to quickly see loads of useful information about your MacBook's battery:
- charge level
- capacity
- original capacity
- time remaining

It's FREE! No reason not to download it right now! Enjoy!

If you would like to get rid of the built-in battery monitor:

1) Go to System Preferences -> Energy Saver.
2) Uncheck the box at the bottom that says: "Show battery status in menu bar".
