Would it be possible to remove the battery using a heat gun?
As Apple offers battery replacement, it has to be doable without risking puncture, etc...
I wonder if applying a heat gun to the other side of the aluminum case would soften the glue and allow for removal of the battery. (The same procedure as removing the screen on an iPod touch/iPad.) Since the battery is compartmentaliz
Remember that in this case, the "bottom" of the MacBook Pro with Retina Display is actually the keyboard/trackp
The battery is removable, it's just very, very hard to do. The biggest issue is with the trackpad cable that's being routed under the battery, as seen here. One slip of the spudger / ruler / whatever you use to dislodge the battery could shear that cable, resulting in having to replace the trackpad as well.
The whole battery is held in place by a frame. You can dislodge the individual pieces partially, but you need to lift the whole enchilada out at the same time. Otherwise a.) at the very least you'll break the frame connecting them, or b.) you'll puncture one of the batteries and have a nasty, smelling, dangerous mess to clean up.
I speak from personal experience. :)
I assume Apple is looking for expediency to save time and money as apposed to doing it right thus taking a bit more time.From a maintenance point of view it will be more costly for them to perform a battery removel and replacement.But as this will be probably few and far between it must pay for them to do it this way.
