Ive searched a few post on here and most guys agree the batteries made by Johnson Controls are top notch. Also most guys agree that batteries made by Exide are not so good. How do you know who made the battery you are looking at? In an older post one poster said the batteries at his local China Mart carries the ones made by Exide and another poster said his local China Mart still carries the good ones by Johnson Control. Just curious so maybe I could tell the difference and not wind up buying a house brand made by Exide.
