Battery calibration is not necessary unless your computer is shutting down when the computer is reporting more than 1-2% battery life remaining.

According to Apple, battery calibration should be performed at least once every two months.

Did you even read the page you linked to?

If your portable Mac has a built-in battery, you don’t need to calibrate the battery.

I skimmed over it reading the first half of that sentence and naturally assumed the steps following applied to that phrase. Thanks for the correction.

The built-in batteries in the newer Mac unibody notebooks come pre-calibrated and do not require regular calibration like the removable batteries.

This should answer most, if not all, of your battery questions:

I'm very confused. It says Macbook (Pros) does not need to be calibrated, yet the guideline says "Macbook Pro (All models)" followed by instructions on how to calibrate. Do I need to calibrate or not with my macbook pro 13" Late 2011?

The calibration instructions are only for models that require calibration. Yours doesn't require calibration.

The CALIBRATION - NEWER UNIBODY MODELS section is pretty clear in identifying which models don't require calibration and states, "For models that require calibration, see the CALIBRATION section below."

So my macbook will never need calibration? Why are so many people doing it in the macbook pro section on this forum?

Because so many have older MBPs that require it. As stated in the FAQ, if you suspect your battery readings are inaccurate, it won't hurt to calibrate, but it shouldn't be necessary with your model.

Many people have a hard time adjusting to changes, and have a tendency to stick to 10 years old wisdom.

People still use screen savers after all

The battery capacity is deceasing.

What model Mac do you have? The built-in batteries in the newer Mac unibody notebooks come pre-calibrated and do not require regular calibration like the removable batteries.
