cocunutBattery is a very cool application for Macs. you can see all about your battery, the age of your mac, and how much it holds compared to how much it held when you first bought the mac/battery, and even battery load-cycles. The application is very simple, and that is about all it has. it only works on macs.
this is very interesting. according to coconut, your battery capacity has increased since you first got it. how is that possible?? thanks for showing this to us. it is really interesting.
