I have a 2003 ION that I'm selling. The only thing is that it's been sitting in backyard for about four months. I tried to jump start it and although I get 12+ volts into the battery and all the lights and alarms energize, the car will not start. It doesn't turn over, it just clicks. I can't imagine the problem being anything but the battery since it has not been driven. So, I guess I don't know a lot about car batteries. Does jump starting a car mean that you're also charging its battery? Can a car battery be re-charged? Should I have kept the car with the good battery that I was jumping from on longer? Should I just get a new battery? Suggestions? Thanks. -ac
