CoconutBattery – Extended Battery Information
If you own a Mac laptop, you’ll want this app. CoconutBattery provides the usual current battery charge information, but that’s not what makes it cool. Anyone that has owned a device operated by rechargable batteries can tell you that over time the capacity diminishes. That is what makes CoconutBattery so unique, it provides detailed information on your batteries life, comparing original and current battery capacity.
You can also save battery data at will, allowing you to compare your batteries health and lifespan to usage statistics and the time passed. This is particularly useful if you are always on the go and are curious how much usage you can really get out of a single battery. CoconutBattery can also tell you how many loadcycles your battery has had in total, the age of your Mac, if the battery is charging, and if your charger is connected.
