Good point, Qsilver. I have always used the engine bay connections. I use the automatic setting rather than the quick charge option. I have used the high output position a few times but only when the battery was low and I wanted to have enough juice to start the engine and then immediately remove the cables and use the alternator to charge the battery as I drove.

Why is the battery dead? Do you know it is a good battery?
