From what you describe, it has all the earmarks of a dying battery.......

Or test the electrolyte for specific gravity. Sounds like a battery issue to me too. Basically, if the battery is 3 yrs. old or older, it is always suspect.

Lead Acid batteries also incrementally lose their ability to hold a charge with each discharge. After about 5 discharges, it's usually shot. This would be exascerbated in cold weather too.

Bottom line, quit p*ssing around and if it's 3 yrs. old, replace it and be done with it. Last thing you want in a Chicago winter is to be stranded in the cold by a so-so battery.
