A couple of days ago my car died while our running errands. No warning just wouldnt start. So I figure, battery, starter, altinator as the cultrate. My wife comes and jumps me and I go home. Can wont jump again....wont hold any charge... So I figure battery. GO get a new one and the next day take the battery back for core change and figure I would have it tested.
Apparently a car battery should hold something like 12.5 volts they test mine and it would hold like .3 volts.
It died almost 5 years to the day of me buying the car.
