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? :confused:

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.

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.
