My voltage meter is showing in the 9 range when i crank my car for start up. What do you guys see on your cars with a mini battery kit?

Seems like no one understands the question. While your car is cranking the voltage will drop below 12v. That's what the op is asking. So what is your voltage while cranking? Not before or after starting but while cranking. You only have that sec or two to get the reading unless you disable starting. Hope this helps
