You can charge a dead car battery.

Leaving headlights or interior lights on while the car is turned off is one of the reasons your car battery could die.A functional car with a charged battery and a set of jumper cables are required in order to charge a dead car battery.You can use the jumper cables to connect the batteries to one another and then transfer the energy from the functional battery to the dead one.Continue reading to learn how to safely and effectively charge a dead car battery using jumper cables.

Step 1: Before starting your car, check the battery's appearance.

Your battery should be free of cracks and leaking battery acid.If your battery shows signs of damage, do not attempt to jump-start your car, as you may cause injury to yourself or others.

Step 2: Before touching the dead car battery, wear safety goggles and rubber gloves.

You can protect your eyes and hands with goggles and gloves.

Step 3: The cables that connect your car's battery to it are secure.

Use a brush with stiff bristles to clean your battery cables.

Step 4: Don't allow the vehicles to touch one another if you drive the functional car next to the dead battery.

Placing the cars next to one another facing the same direction is the ideal position for this task.The jumper cables need to connect the cars together if the distance between the batteries is close.Depending on their style and manufacturer, the length of jumper cables varies a lot.If your first pair isn't long enough, try to connect two different pairs of jumper cable together.This can cause a fire.

Step 5: The car that has the charged battery should be turned off.

Step 6: The batteries are located in the hood or compartment of each vehicle.

Step 7: Take a look at the positive and negative terminals.

Positive and negative terminals will be indicated by a minus symbol.

Step 8: The positive jumper cable needs to be connected to the positive terminal on each car battery.

The positive jumper cable is usually red if it is not labeled.If you follow this pattern, first connect one end of the positive jumper cable to the dead battery, then connect the other end to a charged battery.

Step 9: The negative jumper cable needs to be connected to the negative terminal.

The negative jumper cable is usually black.

Step 10: Attach the negative jumper cable to the grounded metal component of the car.

The dead battery in the car will be ground by this.You can attach the ground cable to a component that is clean and free of paint or oxidation.

Step 11: Start the engine of the car.

The dead car battery will be charged through the jumper cables when the engine starts.

Step 12: After starting the engine of the car with the charged battery, allow at least five minutes to pass.

It would take longer to fully charge the battery, but this will allow the dead battery to build up a charge of its own.

Step 13: There is a dead battery in the engine of the car.

The car engine should start if the jumper cables and battery have enough power.Allow five more minutes for the dead battery to charge if the engine fails to start.

Step 14: After the engine has started in the reverse order in which you connected them, you should remove the jumper cables from each car.

There is a chance that sparks or an explosion will occur.Before attaching the cable to the positive terminal of the dead battery, you need to remove the grounding cable from the negative terminal.

Step 15: Allow the car with the dead battery to run for at least another five minutes.

This will allow the battery in the car to be charged.

Step 16: Allow the jump-starting car to run for at least 20 minutes or drive it for the same amount of time.

In some cases, your battery will be fully charged within this time period; however, it is possible that you will need to purchase a new battery for your car if the battery doesn't charge sufficiently to crank the car.
