Mex Oops my bad as a post is missing.
1. I have the 2x GC2 220AH house batteries to test and appreciate your input. The tester manual says 160AH max for deep cycle batteries.
2. I also want to test group 31 950 CCA starting battery. Mfg says to use 1/2 of CCA as the amp setting for the tester and use the chart I posted. Hence 475A and check the voltage after 15 seconds. I'll try that but am doubtful that the el cheapo home type 500A carbon pile tester will really handle that amount of amps.
So learning how to interpret the results and record them so that I have a baseline for the batteries to compare in the future for changes.
Others may have L16 or 8D batteries and need a 800A+ tester but I'd like to have a reasonable expectation of a good test with my batteries and the 500A tester.
