Sorry, the individual batteries read 12.89V +/- 0.04V, not 25.89.
The hygrometer does not have a temperature correction. It's just a simple float. I had the AC running all night, so battery temp was probably closer to 75dF.
Yes, I did completely disconnect all batteries when I did the CCA tests...and all showed greater than the rated 600CCA. Seems odd that CCA reads better than advertised and SG shows bad batteries.
I'm in touch with both the Interstate battery people and the Charles charger folks. It'll be interesting to see what they say.

Why did you measure voltage in pairs?
You said, "...checked the individual voltage on each battery. All batteries were at 25.89 V."
Although it probably has nothing to do with your problem, you did not check them individually if the voltage was 25.89.
You did not mention any correction for temperature. Did your hydrometer have a built in thermometer to correct the reading to 80 degrees F? However, this would not be significant with your readings because you are probably at about 90 degrees and the correction to 80 degrees would only correct the 1.150 to 1.154.
It sounds like your 1 month old batteries are acting like they are at end of life.
Is the Charles 60 selector switch set for lead acid?
When you used the SOLAR battery tester, did you actually check each battery individually and with the battery totally disconnected from the bank, both positive and negative? if not, totally disconnect a pair of batteries at a time. Let them rest for at least 30 minutes (2 hours may be better), then test each one. Then do the next pair until you have done all 4 pairs.
