Our batteries are rated at something like 220 Cold Cranking amps, but obviously can't sustain that for very long .... IMHO, the 100A tester would be ok for a quick test of the battery's reserve capacity ...
If you wanted to test R/R & stator I think I would use one of the more expensive testers that allows the load to be adjusted down to match our charging system max. output (~30A) would be better .....
