      I suspect their tester. You need to do a load test for a few minutes and see how well the voltage holds up. You can get a 100 amp tester for $25: http://www.harborfreight.com/100-amp-6-volt-12-volt-battery-load-tester-90636.html
      
      I was going to use these Walmart batteries for my tractor but there were some reviews that indicated problems:

      I think I might use a slightly more expensive version from Tractor Supply:

      Or you might consider SLAs which are about $0.16/Wh (but more if you consider Peukert):

      You can't check IR without having them under load. Maybe 2 of these in series? http://www.harborfreight.com/100-amp-6-volt-12-volt-battery-load-tester-90636.html
