So I just opened Coconut battery, and it is saying that I have 101% battery capacity. How is that even possible????

In the other hand, iStat says 100%.

yup I have had this happen, could be an error by either one of the programs, or your mbp battery may have 1% more than the standard amount.

After all, when you buy a car that says it makes 300 horsepower, what are the chances it actually does?
 
A lot of topics on batteries tonight lol.

My 13000 mAh battery (as per specs) reads a tad higher than 13000, but it still says 100% capacity (but it isn't more than 130 over to necessitate 101%)
 
Not all batteries are within spec. Some batteries have higher or lower capacities.

NATURAL.
 
Mine is the same. Though it's also saying that my battery is at 99% charge after having it plugged in all night and booting it up. The capacity has been going up and down- currently at 5857mah of the designed capacity of 5770mah. It went from 5814 to 5788 in a day, and progressively back up to where it is now. My MBP is only a few weeks old if that means anything and I haven't properly "calibrated" the battery. I've drained it pretty low and then charged it back up a few times but that's it.

You should calibrate it before taking a look at any of these results, Apple does not calibrate the batteries before sending the laptops out.
 
100% just means 100% designed capacity. Some battery are below some above that and each will go well below at some point in time.
