I went to start my car up a last week and found it was dead. I thought it might be because I hadn't driven it in a couple of weeks. Horrible, I know, but I live in Chicago and we do have to deal with the snow. Anyway, i jumped it and car drove fine. Couple of days later and same problem. Think it's time to replace mine now, also. The current battery is an Interstate. Any recommendations on where to get a battery and what brand?
