There's no set answer to that, it depends on the battery chemistry, how much the battery has been used since full, and what the battery is hooked up to. But basically, when new, every battery, when hooked up to a modest load, will have a tad more than the rated voltage - in this case 9 volts.

How many watts in a 9 volt battery?
The question should be how many amp-hours in a battery. In a small batt. like a 9V, this is measured in milli-amp hours (mAh), with 0.5 amp hours equaling 500 mAh. This means the battery could power a 0.5 amp load for 1 hour. Data I have seen shows the best alkaline 9V being between .3 and .5 amp-hour (300 to 500 mAh).
