Re: CCA Cold Cranking Amps?
For $20 is inexpensive. If you know what the voltmeter reading should be, an alternate way is with the ignition off, engage the starter for a 5-10 seconds while monitoring a voltmeter at the battery, and it should not dip below a certain level. Then see what the battery is at when you are done.
If you are like me with poor memory, usually can not remember or find the info - prefer to spend the money on the tester.
