Seeing that we are talking Batterys.... or going batty


I just purchased a Celestron Power Tank 17
Jump Starter Unit.
12v/17ah sealed battery.
Has 12v & 3,6,9v sockets.
Also got a Inverter 500w the other day (for running my XPS M1710)
Now what sort of usage would i get using as well as HEQ5 Pro.
Can the Oh Mighty Battery Man

tell me this....
Bow to his Greatness
