It's not. Batteries are not an exact science. Unlike the gas tank in your car which has a float and a sensor to judge the position of the float, there is no way to accurately meter the capacity of your battery. Those ratings are little more than "educated guesses" based on your usage patterns.

Over time you will likely see these numbers fluctuate as the SMC learns more about your battery's discharge patterns. For right now, I wouldn't sweat it. Now, if you see the battery health at less than 90%, that would be a different story - for now it's fine.

Liquid and computers don't mix. It might seem simple, but we see an incredible amount of people post here about spills. Keep drinks and other liquids away from your expensive electronics!
