Yes, that is correct.
By there positive and negative connectors and there acid.
Connect Positive on A to Negative in B then Positive from B to whatever Positive on A had been connected to.
Car batteries will make a larger explosion than flashlight batteries would.
NO! positive is red and black is negative negative is grounded to the frame of the car, and positive goes to the electrical components.
If you incorrectly connect two car batteries together, i. e. by crossing the cables (negative to positive, positive to negative), one or both of the car batteries will soon explode. The resulting acid splash will cause severe burns to the nearby onlookers.
Normally Positive (+) is RED and Negative (-) is Black.
two 12 volt batteries. positive to negative between the two batteries then hoock up your positive on amp to pos of one battery negative to the other battery and you will have 24 volts.
You just connect negative to negative and positive to positive. Click the link for a diagram.
If the car is a 12 volt system, then you will want to connect the batteries in "parallel". IE: negative to negative and positive to positive. Because of "cranking amps" it would be advisable to use a cutoff switch when starting the car. (The switch would interrupt the power from one of the batteries so the amperage wouldn't toast the starter) Also, the alternator should be isolated as to charge the batteries one at a time.
You conect them in parelell. Positive to positive, negative to negative, with either a 12 or 6 volt system. if you conect them in series you will double the voltage.
You could put them in parallel--wire positive to positive, negative to negative, then connect the positive and negative wires to the car. This would give you twice the current capacity, and you'd be okay because the car's only going to take as much power as it needs. If you wired them in series--positive on the first battery to the car, negative on the first battery to positive on the second, negative on the second battery to the car--you'd double the voltage and burn the car out.
On the car battery, the positive wire is red and the negative wire is black. If the body of the car is metal or conducts electricity, then the body of the car serves as the negative wire. The metal in the engine serves as the negative wire.
