how many volts does my battery need to start car
The voltage on the battery was at 11.5 volts. When I jump start it the car fires up on the first try. My battery is a 6-month-old Optima (red top)and I checked for draws on the battery with an ammeter and there is nothing out of the ordinary. I checked the volts on the battery with the car running and it's at 14.5, so the alternator is charging OK.
