coconutBattery
Your decision to buy a laptop probably was motivated by the ability to use it where you see fit whether that be on the couch, the patio or the car. Your MacBook’s battery dictates how useful your computer is away from power and in turn it’s worth ensuring that it remains in optimum condition. Beyond following Apple’s advice on maintaining your Mac’s battery, monitoring the condition will give you a good idea how your battery is performing.
CoconutBattery does just that - it provides you with a stack of information that is useful for monitoring your batteries condition. The application allows you to see how much battery power is left on your current charge as well as the capacity of the battery which always depletes as it ages. Beyond providing vital statistics in the present, coconutBattery allows you to log your batteries total capacity which allows you to compare the depletion over time.
In addition to monitoring your batteries condition, to make the most of your MacBook’s portability Apple recommends adjusting the Energy Saver features, adjusting your displays brightness down and turning off unused features such as AirPort and Bluetooth when using your MacBook on battery.
