  • 12v or 14.4

    " Most car batteries, though rated at 12 volts, actually deliver 14.4 volts. "

    I read that on crutchfield. Is that true?

    Yes. But it depends on what load/current is being drawn from them. I think the 14.4 is when your alternator is working. I think if you just measure of battery sitting there, it should be closer to 12.6v.

      The battery in your car is a 12.6V battery.
      The charging system in your car is a 14V system.
      Basically the alternator is charging the battery above 12.6V....generally around 13.8-15.2V is normal with the engine running. Any higher or lower and you have a problem.

        When I was selling batteries, they put out about 2.2 volts per cell. That comes out to about 13.3 volts for a 12v battery. The voltage can vary depending on how well the battery is maintained, but I have never seen one higher than 13.3 volts.
