Modern automobile batteries are 12 volts.
12 volt
Connect them together in Series. Connect the negative post of one battery to the positive post of the other battery. Then connect the negative charger cable to one negative battery post and the positive to the positive post of the other battery.
NO, a 12 volt battery cannot be charged with a 6 volt charger. To charge any battery, the charging voltage has to be, at least, slightly higher than higher than the voltage of the battery. Current flowing through the battery is what accomplishes the charging, and no current will flow at or below the voltage of the battery to be charged.
I have to assume that you're talking about a 6volt battery.The answer completely depends on the size and capacity of the battery.If it's a 6volt car battery that's fully charged when you connect the radioto it, it ought to run that radio for days. If it's a stack of four AA-cells inseries, they won't last quite that long.
yes as long as it is a 12volt battery - i have done it many times.
12 volts battery.
it is a neon green light in a plastic tube powered by a 12volt car battery
6n12a-2d is a 6volt battery the es9bs is a 12 volt .
No.
Chargers don't care is the battery is used on a boat, a car, or whatever. What is important is that you match the voltage of the battery and the charger. Don't use a 12volt charger on a 24volt battery, etc.
Yes it will, in the 12-volt position. But with the information given in the question, we can't estimate how long it will take.
If the capacitor is charged then the battery will explode.
