The battery in the sd has really been below par lately. It turns the car over just slow enough to not start. Even hot. And since these things im guessing are like 100 bucks new how can I get a little more life out of it? I know its not the alternator as I put my 300d's battery in it and its been good for about a week. What about slow charging? Say an amp or so? Do battery's actually need to be "refilled" with water or is that just something from the 70's?
And how much more is the white battery than just a standard autozone battery? I want the white one
