12v tester or 6 volt? did you test them in series? Did he charge them at 14.8 volts for at least two hours before testing?

The tester was a handheld device about 14" x 6" x 1" with a screen readout. On the marine setting it asked for amp-hours and we put in 210. It worked away for about 15 seconds and announced that the battery was bad. The batteries were tested in series at 12V.
They were charged overnight by the converter on my trailer and then tested. I don't know the answers to the other questions.
