Best way to use Macbook pro battery?

First of all, don't drain the battery every time! this is very Important. Only drain it completely once a month to calibrate it. You are supposed to charge it whenever you need, such as when your battery is at 45, 32, 76, 82, it doesn't matter! as long as you don't drain the battery below 10 percent every time. this is what is lowering your health. Also, the battery health will vary, mine switches between 100 and 99 all the time. I would only worry if it gets below, say, 93 percent health. With older laptops, you were supposed to drain them completely, but with new battery technology, the batteries are made to be charged before they are empty.
