I was looking at a sentra board and someone mentioned a 20lb+ weight saving going to a Dyna-batt

http://www.hepi.com/default.htm . I think that the stock Civic battery is smaller than a sentra battery so the weight saving might not be as much. Anyone weighed the stock battery compared to one of these lightweight ones? They seemed to have a descent amount of Cranking amps. Just wondering.
