During the Bane fight the book says they are equally matched. During the fight Bane breaks a pipe and water shoots at Batman. The blast catches him off guard and he doesnt see what happens next.

When Bane storms the stock exchange an officer inside presses a red distress button, which sets off two alarms, one in Gotham Police station and the other in the batcave. Bane downloads bank account numbers, security codes and personal records from the stock exchange computer. Alfred hands Batman the EMP gun before going out. The book has a sequence where Batman chases the motorbike guys on the batpod, as well as Bane. One book has Bane getting away, and the other has Bane getting caught (which obviously won't happen)
The Bat has an EMP guidance mount on it.
