coconutBattery is a simple app for Mac laptops that reports on the device's battery status.
If you believe your computer's battery life has decreased significantly, you can use coconutBattery to compare the current battery capacity to the factory default. This app can also display information about the remaining battery charge, provided it is in use, or the age of the computer.
In addition, it has a simple logging feature that's very useful for storing information related to your battery status.
