How to calibrate changed battery. Early 2013

I just changed my battery in my Early 2013 MBPR and need to calibrate the battery. It says to let it drain overnight and then charge to 100%. Do I turn the laptop on to let it drain? Am I correct that I shouldn't use it before it is fully calibrated?

Answer this question I have this problem too

Is this a good question?

Just turn it on without the Mag-Safe adapter. Play some uTube videos till it dies, then recharge. The best tool to check it out id Coconut Battery: http://www.coconut-flavour.com/coconutba...
