Thanks goes to Mac for reminding me about prepping a laptop battery before first use.
When the new notebook arrives, fight the urge to use it immediately.
(1) Plug it in and let it fully charge and don't turn it on or use it.
(2) After it fully charges, let it drain completely.
(3) Then fully charge it back up to full before finally starting to use it.
Apple has some more details for the Macbook and Macbook Pros on how to calibrate.
Some other info on Apple's site on taking care of your battery.
