Well, I'm up to a big fat 7000 miles now on my 2008 Bullitt. I wind up driving it maybe once every week or so on average and would like advice on maintaining the battery. I know that one obvious answer is a trickle charger. But otherwise, realistically how often and for how long would I need to be starting it and/or driving it on a regular basis in order to preserve the battery? I live in Virginia so the weather here allows me to drive it pretty much all year long.
