I'm assuming you want dual batteries for increase amps /hour off road use.
If you want to get 12 volts out of 2- 12 volt batteries you will be wiring them in parallel. Wiring batteries in "Parallel" increases there combined Amp/hour capacity, but their voltage stays the same. Battery 1 Positive, to Battery 2 Positive, and Battery 1 Negative to Battery 2 Negative is Parallel wiring, retaining the voltage rating of either one of the batteries. I suggest adding a "Battery Cut-Off Switch" in the circuit.
Try doing it outside your vehicle and use a multimeter set to DC volts and test for 12-16 volts (higher readings would require it be on a charging system).
If you do this wrong and do not test it first YOU MAY FRY your vehicles wiring system by overloading the 12 volt system by running 24 volts through it.

What does it mean to say that your car has a 12V battery?
12 Volt BatteriesThe 12 Volt designation of a battery indicates that the nominal output voltage is 12 Volts.
What does 12 volt mean in the context of a battery?
It means the voltage output of the battery is 12 volts DC.
How do you charge a 12volt battery from a 220volt home system?
With a 12 volt battery charger that is made to plug into a 220 volt circuit.
How many volts will a new 12 vot car battery put out?
A fully charged 12 volt battery will output 12.6 volts are read with a digital volt meter.
Can 12 volt charger charge 3 batteries wired in series?
No, if they are wired in series you have 36 volts assuming each battery is a 12 volt battery. They will have to be wired in parallel to output 12 volts. In that case you can charge them with a 12 volt charger but it will take 3 times as long as charging just one 12 volt battery.
Can you charge a car battery with a motorcycle battery charger?
Unless it's an old vw bug, cars usually run on a 12 volt dc system nowadays. Motorcycles often run on a 6 volt dc system. Different systems require different charging voltages so you won't ever be able to charge a 12 volt car battery from a 6 volt motorcycle battery charger as the output voltage would be way too low. However, if you can set the battery charger's output to give either a 6 or a 12 volt output, then you must always remember to set it to 12 volts if you want to use it to charge a 12 volt car battery.
How you charged the 12 volt battery?
Charge it with a 12 volt battery charger.
When you have a linked 48 volt system can you use one of the 12 volt batteries as 12 volts or are they all 48 when linked?
You can pull 12 volts off of any single battery in the circuit. The output from each battery never changes, it's always 12 volts. Those batteries are wired together in SERIES to increase the final output voltage of the entire circuit to 48 volts. To demonstrate this, place a voltmeter across the positive and negative terminal of any battery in the system. It will read 12 volts, regardless of which battery you're measuring across. Now place the voltmeter from the positive terminal on one battery and the negative terminal on a different battery. Depending on how many batteries you're measuring across, it will read 24, 36 or 48 volts. Practical application - connect your 12 volt device from the positive terminal to the negative terminal on a single battery.
Can you jump a 6 volt battery with a 12 volt battery?
No
Is the battery on a Honda four wheeler a 6 or 12 volt battery?
12 volt
Can a 12 volt charger charge a 8volt battery?
No, a 12 volt charger will overcharge a 8 volt battery and destroy it.
What is the voltage in a circuit?
zero That's not always true. If you have a 12 volt battery not connected to anything and you measure the terminal voltage, it will be 12 volts.
