My battery is the original ac delco and i drive an 03 gt. how much longer is this battery going to work for me? I know that is a kind of a toss up question but are batteries ever known to run this long or longer. my next question is what kind of battery should I get next? this one is still kickin strong but i was thinkin about starting to save some money for one. I wouldnt need the nicest thing but I also wouldnt want to replace it very often.
