coconutBattery is a handy little application for Mac laptop users. It gives all kinds of useful information about your battery, like what the original charge capacity was vs. what the current charge capacity is. This is very helpful in determining if your battery is about to die.
coconutBattery comes in 2 flavors… an application, and a Widget (for Tiger users). I highly recommend it.
When you head over to coconut-flavour.com, to download coconutBattery, you should also check out coconutWiFi, and coconutIdentityCard, 2 additional utilities by the same developer. They’re both pretty handy.
