The only "funky" bit we came across in the MacBook Pro was a Y0 Tri-point screw holding down the battery. Luckily, we were prepared and had our 54-Bit Driver Kit on hand.

Our faithful spudger helps us disconnect the battery, which you should always do when performing repairs or maintenance on your MacBook Pro.

Apple's battery warning labels haven't stopped us before, and they're not stopping us now.

The battery is exactly the same as last year's model—77.5 Wh at 10.95 V.

In case you missed it last year, this battery is 13.8 mm thick and weighs 450 g.

By comparison, the battery in the MacBook Pro with Retina display has cells that vary in thickness from 5.25 mm to 8.60 mm.
