all i know is to use a A23 12 volt battery, costs nuthin and if it doesn't work for ur needs, omen it and get a bunch of button cell batteries
aha! combine all of the 1.5V button cells from two A23 batteries to make 18v, tape them together and that is it!

You might try three of the square/rectangle 6v "lantern batteries" in sequence. As a last (expensive,but awesome)resort you could go with three 6v (rechargeable) motorcycle batteries. I don't think 2 of the little 9's will run it.
What was the old battery?

i used to run it on a single 9V battery, but it needs at least 12V to go fast enough to cut things
