cool or not? i am thinking that it is fine, as long as im not worried about using the low battery light and the auto shutoff
it is just gonna be a one time deal for tonight, then im on to a 9v wal-mart batt
6v sla is DEAD and wont take a charge,a nd the show is tonight, and no place anywhere near to buy the stuff to do it, or time enough to go get a walmart 9v and charge it...
