If you have a battery tester put a load on it of 250 amps if it has an adjustable rheostat then watch voltage if it goes down to 9 volts you need a new battery.

It sounds like you are using a conductance tester. The CCA input is just used to create a pass or fail point. You will still get an accurate CCA reading from the test no matter what number you put in there. I usually just guess at the number. You can also use a battery application catalog and that will tell you what the required CC is for that vehicle. Yours should be around 500 to 550 CCA.
