I have a 2004 Saturn Vue 4cyl 5 speed. Recently I have had problems starting my car. I bought a cheap charger from Walmart for $30 and hooked it up and everything seemed fine at first. Now I am having to plug it in every night. The battery is less than 2 years old and I am unable to figure this one out. I checked to make sure there are no lights or anything that might be left on that would cause the battery to drain and have checked connections. The battery has tested good as well as the alternator testing good. Both were tested 2 weeks ago and the problem persists. Any suggestions?
