Okay, I lost you at "found a 9V 1.5A one at the thrift store". What exactly did you find ?

Look, volts don't equate to amps, and are unrelated to current draw. If you don't know what you're doing, you might very well start a fire. Don't do it.

I'd be happy to guide you through the process of getting the right battery for the right application. But please, don't burn down the house playing with batteries. Okay ?
