The Ballistic is designed as a starting battery and works great. Cost benefit isn't there at all, but it costs money to get rid of weight and it was pretty cheap to dump 12 pounds of fat off the big pig.
Have you read about how to use this battery? It doesn't do things like normal batteries, read the FAQ at Ballistic and try it again.
