It is not a great idea to solder directly to the ends of a battery. If you hold the iron on it long enough to get a good joint, the battery probably would no longer work. If you don't hold the iron on there long enough, you get cold solder joints that probably won't work either or would be completely intermittent. Buy a battery holder, or 9V battery terminals with wires would be a MUCH better alternative. If you don't believe me, then look at a built battery pack, why do you think they spot weld the metal strips to hold the pack together and have wire strips that you can solder a wire to!
