    This is what you want to do:

    1) Plug in the power adapter. Let the battery charge to 100%. Let it sit, plugged in at 100%, for at least 2 hours.

    2) Unplug the power adapter and continue to use your Mac while on battery power.

    3) Let the computer put itself to sleep when it gets to 0%. Let the computer sleep at 0%, without plugging in the power adapter, for at least another 5 hours (i.e., let it sleep overnight).

    4) Plug in the power adapter and let the battery charge back up from zero to 100%.

    That should properly calibrate your battery. It doesn't hurt to do this every few months. You can use a free application called "Coconut Battery" to monitor battery health. You can find that here:
