New Rovair compressor

[Clyde]

I just purchased yesterday a new Air Venture Rovair compressor to fill my Brocock Compato .22 rifle. I have been using a steel scuba tank and getting too old and weak to lug the heavy tank around.
Anyone want to venture a guess as to how long I could run this on the 12v system if I used a large motorcycle battery, ie. Honda gold wing or pre fuel injected Harley. Don,t care to run my car battery down and leave myself stranded.

If you have the vehicle running you will not run your battery down, my compressor(not this one) says not to use w/o car/truck running.
