7805 voltage regulator explosion

hello, I am working on a new bot and I am planing on using a 9.6V 1000mAh Ni-Cd battery with a 7805 regulator. As I was making the small board to regulate the power to a picaxe friendly 5V I hooked up power to the board and was soldering the battery on  (battery is allays to be used at 5 volts.  I needed cheap on hand method because I had no connectors for the battery) when the 7805 blew up.
