Apple will replace the cable on the 2012 13" for free. Best to go to an ASP for this rather than an Apple outlet as Apple pays them to do the repair. The battery has nothing to do with it. Look at the cable where it comes over the last step. The bottom hit it and damages it. When you take the 2012 in for the free replacement, ask to buy another one and put it in your 2011. Put some kind of pads on either side of the cable so the bottom will not hit it.
