coconutBattery is a simple utility that goes beyond just showing you the current charge of your MacBook’s battery. You might say it gives your battery a complete physical exam. coconutBattery can show you the current maximum capacity of the battery compared to what it was when you first took it out of the box; perfect for anyone who’s thought “the battery used to last longer.”
The diagnostics don’t stop there. You can get a better idea of how many complete charge cycles are left in the life of your battery by checking the loadcycles (how many times you’ve fully charged your battery) – useful because every battery has a set amount of full battery charges before it just doesn’t charge anymore.
If you’re a multiple-laptop family, you’ve no doubt been faced with the question “is that the MacBook charger or my wife’s MacBook Pro’s charger?” coconutBattery can let you know if you’ve plugged your laptop in with the wrong charger.
coconutBattery is a free, Universal Binary you can download here.
