Normally in off load, its about 12.6 volts.
12.6 is correct for a fully charged battery.
12.4 it is 75%
12.2 it is 50%
12.0 it is 25%

What is the voltage of one cell in a car battery?
2.2 v when fully charged.
Will a bad voltage regulator keep a 1995 sebring from starting up with a new car battery?
No, not if the battery is fully charged.
What voltage is a Honda Civic battery?
Any modern day car's ideal battery voltage is 13.8Volt. In practive however the voltage you'll find on a charged battery when testing will be in the region of 12.5V to 13V A fully charged battery will read 12.6 volts with the engine not running. With the engine running at idle speed it will read from 13.5 to 15.5 volts.
How many amps does a car battery have when fully charged?
It varies by manufacturer and battery.
Can you overcharge a car battery?
You bet you can. That is why it is always advisable to use an automatic charger that shuts off when the battery is fully charged. If you do not have one then charge it for a couple of hours and then remove the charger and check the voltage at the battery. A fully charged battery will read 12.6 volts. 12.4 at 75% charge, 12.2 at 50% charge, and 12 Volts at 25%. If it is not fully charged then put the charger back on a little longer.
What is the voltage of most car batteries?
12.6 volts when fully charged.
What is the duty of an alternator in a car?
It is there to keep the battery fully charged.
A fully charged typical car battery has?
12.7 volts
What is the specific gravity of a fully charged car battery?
1.265
What is the lowest voltage reading of a battery you can fit?
Since this question is in the car battery category I am going to make a couple of assumptions:Most 1960 vintage and older automobiles were equipped with a six volt battery, the minimum usable voltage of these batteries is 6.1 volts fully charged is 6.6 voltsMost 1960 and later automobiles are fitted with a 12 volt battery, minimum usable voltage is about 12.1 volts, fully charged is around 13.2 volts
Can you charge an ATV battery with a car battery?
I am assuming you mean with the auto engine running. Yes, that is possible but you are putting a strain on the alternator of the car. An alternator is not designed to charge a dead battery. It is designed to keep a charged battery fully charged. as long as the ATV battery is the same voltage as the car battery, usually 12 volts, you can charge it, or jump start the atv and let it charge the battery itself.
Why can a car battery have an open-circuit terminal voltage of twelve volts but be unable to start the car and thus be considered dead?
A fully charged cell in a car battery produces 2.2 volts, there are 6 cells in a battery. That would make true open circuit voltage on a fully charged battery at 13.2 volts. So a 12 volt open circuit reading is a discharged battery. The battery can have enough chemical reaction to produce voltage but not enough potential or power to crank the engine. Think about a fresh 9 volt battery. It is big enough to produce 9 volts, but not enough to crank a car or even light the dome light dimly. A car battery wears out slowly from the time it is purchased. Eventually it doesn't have enough power or amperage left to operate the car.
