Ok I have a dimming going on of my headlights and my dash lights when I am braking lately - and although my car starts every time and has not had a dead battery - if this is a symptom of a weakening battery I would like to replace it before winter so I do not end up cold at the side of the road - I tried to see how old it was but the marking on it did not make any sense to me at the time I looked - I looked for loose connections but did not find any -
