MBP 2012 Battery Calibration

[phas3]

So let me get this straight, the new macbook pro's do not need to be calibrated when you first open them?

So when do you calibrate? once a month?

Also I'm trying to understand the instruction for calibrating later

The battery calibration for the PowerBook G4 (15-inch Double-Layer SD) and any model of MacBook or MacBook Pro has been updated because of a new battery released with this computer. With these computers, follow these steps to calibrate your battery:

-Plug in the power adapter and fully charge your PowerBook's battery until the light ring or LED on the power adapter plug changes to green and the onscreen meter in the menu bar indicates that the battery is fully charged.

-Allow the battery to rest in the fully charged state for at least two hours. You may use your computer during this time as long as the adapter is plugged in.

-Disconnect the power adapter while the computer still on and start running the computer off battery power. You may use your computer during this time. When your battery gets low, the low battery warning dialog appears on the screen.

-At this point, save your work. Continue to use your computer; when the battery gets very low, the computer will automatically go to sleep.

-Turn off the computer or allow it to sleep for five hours or more.

-Connect the power adapter and leave it connected until the battery is fully charged again.

for step one can the computer be used while it is charging to full charge? I know step two and three mention that it can be used, I'm just not sure about step one.

You don't calibrate them at all. The built-in batteries in the newer Mac unibody notebooks come pre-calibrated and do not require regular calibration like the removable batteries. The instructions you quoted were clearly for PowerBooks and earlier Mac notebooks. Read the link above for information about newer unibody notebooks.

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