How to Use Jumper Cables – Full Guide in Few Steps

Posted by


What’s more frustrating than stepping out of your vehicle after a tiring day at work and finding the car’s battery. Perhaps you forgot to turn off your interior lighting on, or your battery is simply at it’s end lifespan. In either case, battery problems for cars do not typically show signs that they’re in trouble, until late and the car won’t even start.

Therefore, no regardless of how old (or brand new) your vehicle is, having a functioning collection of cables for jumper connections and understanding how to use them is essential. The first step is to find the perfect pairs of cables. If you truly need cables then any pair can be better than no set at all however, if you’re purchasing the latest jumper cable, Popular Mechanics suggests cables that range from four to six gauge, and at minimum at least 20 inches (6 meters) in length. The extra-long cables can help and help connect batteries when you don’t have two cars right close to one another. You should also look for jumpers with more robust cables and heavier clamps. They’ll last longer in their use and will last longer.

Manage the Cables

When you’re ready to recharge the battery it’s crucial to manage the cables correctly. Keep the black and red clamps away from each other, and ensure that the cables are separated when you’re setting them up especially when you’ve got the clamps attached to a battery that is live. If the clamps meet during the time they’re “hot,” it could cut off either or both of the cars and certainly cause sparks.

Because using jumper cables improperly could be risky, make sure you be sure to follow every step with care. Many jumper cables come with instructions on them or a label to ensure you’re connecting them in the correct method.

Connect the cables

  1. Start by parking the car with the battery that is good close to the vehicle with the battery that is dead.
  2. The hoods of each car and look for the batteries. When the battery is protected by plastic hoods, take off the hoods until the posts of the battery are exposed.
  3. Look for posts that are positive ((+)) and Negative (+) posts. Positive posts could be red, but not always the case, therefore, it’s recommended to search for the plus or minus symbol to identify the post’s direction of polarity. (Before you put the clamps on ensure that you remove all dirt and debris off post.)
  4. Then, take ready your jumper wires and then connect one of the clamps in red on the negative (+) post of the dead battery. Make sure the clamp is securely connected. Connect the other end of the cable onto an positive (+) post of the active battery.
  5. Make sure you connect one of the clamps in black on the opposite (–) end of the battery that is good. Be sure that the clamp is securely connected. However, instead linking the second end of your cable with the negative end that is the battery dead, you can clamp it onto a flat metal surface that is on an engine from the vehicle that died such as screws or bolts. This will ensure that the car is grounded for the jump start.

Start the Engines

  1. Start_the_engine of the car first and then let the engine idle for couple of minutes.
  2. Start the engine of the dead car and allow it to idle for a couple of minutes.
  3. If the dead vehicle starts without issue, be sure to remove its black clamp and the battery first. Then, disconnect the black clamp to the other vehicle.
  4. Then, take that red clamp off your car’s battery. Then,_remove it from the dead battery.

It is recommended to run your car for a long time to aid in the recharge of the battery. However, you must also think about having its voltage checked to make certain that it isn’t in need of replacement.

Do I find jumper cables from gas station attendants?

Although small cables are available at petrol stations, they’re usually not the most effective option. This is particularly true if you’re driving an SUV or a truck. It is recommended to utilize the most robust cables and ensure that they can carry the necessary energy to jumpstart your vehicle.

What do jumper cables are used to do?

Also called Jump leads, or booster cables jumper cables are wires that are insulated. They are sold in pairs and feature alligator clips which are used to connect the battery of a car to another energy source. They could be different vehicles, or batteries with similar voltage to that of the car which requires a jump-start.

Why do I require heavy-duty jumper cables?

The heavy-duty cables are more robust and will have a greater capacity, allowing more electricity to flow through the cable quickly to start the vehicle. This will allow you to start your car in most difficult conditions, such as when it’s cold outside and you’ve got a exhausted battery.

Do I have to turn off my vehicle prior to disconnection of the jumper cable?

Yes! Do not touch the cables if your vehicle is operating. The car as well as the any auxiliary source need to be shut off prior to the connection or deconnection. In the event of a failure, it could cause vehicle damages and could even cause electrocution to the person.

Where do I plug jumper cables?

Make sure that your vehicles are shut off. Connect the clamp red on the negative terminal of dead batteries (often identified by the “+” symbol). Then, connect the opposite end of the red wire to positive of the active battery (or the source used to start the vehicle). Connect your black connection to negative of your “donor” the power source. Connect the black connector on one end to a metallic element of an engine in the car using the battery that is flat. Once the cables are in place to the car, you can start it and then park it. Allow it to run for about a few minutes or so, then attempt to start the second vehicle.
