There are a few ways one can measure battery voltage. One would be to take it to an auto store like Auto Zone or Advance Auto Parts where they usually have battery voltage meters. If one would like to do it on their own, they would need to purchase a volt meter to test the battery life and to see if any cells are dead.

How do you measure the voltage on a car alternator?
get a multi meter that reads dc voltage & touch the black (negative -) wire to the negative battery post & the red (positive +) wire to the positive battery post with car running. car off is battery voltage, car on is alternator voltage.
How is it possible to have a high current with a low voltage such as in a car battery if current equals Voltage divided by Reistance then shouldn't a low voltage produce a low current?
It's all relative. A battery has internal resistance. Batteries are not "ideal" voltage sources. If there is a "heavy" load on the battery (low resistance), the voltage you measure on the outside of the battery will be lower. A car battery is normally thought of as a 12 volt battery. When there is no load (disconnected) you can often measure in excess of 13 volts if it's fully charged. During normal cranking of the engine, the voltage can drop below 11 volts.
How far should the voltage on a car battery drop when cranking the car?
when cranking the engine the battery voltage should not fall below 9.6volts if so replace battery
Can you jump start a Honda ATV from car battery?
Yes, if your car battery is the same voltage as the ATV battery.
Is a car battery a voltage source?
yes
Does a car battery have smaller or larger voltage than a flashlight battery has?
Larger.
What is the proper voltage for a car battery?
12-14v
What is the surface voltage of a car battery?
12.6 volts
Can over voltage kill a car battery?
Yes
Is there any voltage from a battery in an open circuit?
Voltage is a measure of electric 'push'. When there's nothing to push (no circuit) it has no meaning, but that isn't to say it isn't there. Just the same as if you push a car. Take the car away and your push goes away. (or does it?)
Can a car battery over charge it self in the car?
Sure, if the alternator voltage regulator is defective it can overcharge the battery.
Can you describe how batteries are sources of voltage?
The number of cells in a battery determine the battery's voltage. Different types of batteries have different cell voltages. The cell voltage is dependant on the reactive metals used. A typical car battery will have six cells. Because a typical cell voltage has a source voltage of approximately 2.0 volts, this makes a car battery produce a voltage of 12 volts.
