I've gotten REALLY bad about starting up my SUV. I almost never leave the house any more, and I TRY to remember to start up my car...every so often. But I keep ending up with a dead battery. The battery is a top-of-the-line DieHard that's about a year old. I think Allstate Motor Club is getting sick of hearing from me to come jump my battery. The aide we have for my mom has offered to start up my car for me, but she doesn't know how to drive a stick shift and I've been too lazy to go out and show her what to do. So just how often SHOULD a car be started in order to not end up with a dead battery? It's gotten so that it's dying after as little as a week.
