For instance, if we want to remove an old battery from a car, we must first disconnect the cables from the negative terminal. For the majority of vehicles, this is the terminal with black color. Only then will it be safe for you to disconnect the positive terminal, which is the one with the red color.

The positive cable is colored red, The Negative cable is colored black. Red first, then black. Connect the positive terminal first. Attach the red (positive) terminal to the positive battery post. Tighten the terminal with a wrench. Repeat the process with the black (negative) terminal. Car battery terminals will be marked and color-coded. The color red and the plus sign for the positive terminal and the color black and the minus sign for the negative terminal. The negative terminal connects to the vehicle’s metal chassis.
4. What happens if you connect positive to negative on a battery?
Connecting one battery-positive terminal to the other’s negative will cause a great surge of electric current between them. The batteries will then begin heating and a lot of hydrogen will be produced from a series of chemical reactions. This is even worse for lead-acid batteries which are the most common.
5. How do you know which wire is positive on a battery charger?
When a battery charger has two wires of different colors, the red wire is the positive wire, and the black or in some cases blue wire is the negative wire.
6. How to Connect Jumper Cables? Dead Car Battery Tips

Take the positive cable first and connect the positive terminals of the batteries. Then take the negative (black) cable and connect it to the negative terminal of the booster car and a grounded metallic area of your car, such as the engine block. You are then ready to try jump-starting your car.
7. How do you jump-start a dead car?
Jumper cables: You should always keep a handy pair of jumper cables in your car. They can come in varying lengths, normally 10-20 feet. While longer cables can reach farther, you risk losing power as the energy travels along the extra length. Ensure that the cables you use are not rusted, frayed, or damaged.
A car with a working battery: Unless you’ve got a car battery jump starter portable on hand, you’ll need another car to get your battery juiced up. However, it must be the same voltage as the car being jumped. Most car batteries are 12.6 volts or above.
