I have been using them for a couple of years now. Had ZERO problems with them. Very good batteries for the price. I have the bigger C&D one though 100ah. What applications did you use them for? And to the OP, Dekas are very worth the money. Don't hesitate on them because they are only like 80 bucks more shipped at remybattery.com. Don't get yellowtops, they are way over priced. One as a rear bat, in my personal car, two for the geo, one for a Volkswagen golf. All were 12 volt sysytems, stock electrical, and Big three on my car. I only paid 100 per batt, so i have nothing to complain about. edit: here is the one i have in my car.
