Do you ever wonder what’s going on with your laptop battery? Does it seem like it just doesn’t power your MacBook Pro as long as it used to?
Check out coconutBattery which shows you the current maximum capacity of a battery in relation to the original capacity your battery had as it left the factory. You can also find out how many battery-loadcycles (how often did you fully load your battery). This information is useful because you can tell when a battery is going bad (and if you aren't being a good laptop owner). Plus it will tell you how old the computer is, which is useful for birthday parties and whining about needing a new machine. You can get coconutBattery for free by clicking here.
