The important equation to remember is that power of the starter motor is proportional to the voltage squared that is at the input to the starter. The other thing is to know is the internal impedance of the battery source subtracts voltage applied to the starter based on the current that the motor is using. The lower the internal battery impedance, the better.
Yup yup and yup 18V/1.3Ah Nicd

Gentlemen do not dismiss this ten dollar battery or you will be missing out.

John, what are you using to charge the beast?? Is that one of the replacement batteries that Harbor Freight sells?? Or is it mail order only??
