When we are talking about a chemical power unit, the stability of reactions in it varies. Though voltage is important, amperage is the most significant part of starting a car. Many experts assure, you need to wait at least for an hour, then it should drop from 13 to 12.7v.

How Do You Check Your Car Battery Voltage?

As a starting event only lasts a few seconds, the total energy required is pretty small (~6kj) but as the instantaneous current is large, the battery may struggle to. I would consider that normal, for florida anyway.:flag: However, 12.4 volts is minimum and 13.8 volts is typical for the starter motor to begin.

But The Minimum Voltage To Start A Car Can Be Slightly Lower Or Higher.
