I would use this tester in combination with an inexpensive digital voltmeter to get a reading with more resolution.
Asking an FRC battery to supply 125 amps for 5 seconds is no different from what these batteries often see in competition.

That is good to know that this tester may not harm the batteries, as I certainly
wouldn't want to put any additional drain on the battery in the process...
I'm not sure but I am under the impression that when this tester is plugged into a 12 v
battery that it is measuring the voltage under a load (unlike a DMM/ Voltmeter might do)
and the
CCA start test is an additional load test that is selected by adjusting the
CCA voltage on the tester before performing the CCA start test.
Is this correct or is the tester only reading the voltage without a load (like a DMM/ Voltmeter
might do) when the CCA start test button
is not pressed?
I wanted to do more than just measure the voltage as I experienced the same situation once
where we had a battery that measured 13 V and it died too soon during a competition...
Once is enough for me thanks...
Thanks for the suggestions and feedback!
