I wonder who is currently making the Napa group 31 batteries.
Do they say anywhere in small print?
East Penn/Deka perhaps?
http://www.eastpennmanufacturing.com/wp-content/uploads/Deka-Commercial-Batteries-Flyer-0010.pdfThat link shows that Deka makes 11 different flooded 31's, and only 3 of them are 'dual purpose' and they don't bother listing AH or RC figures.
Or do they look like Exide Jars?
