What Common Mistakes Avoid When You Jump Start a Car Alone

Jumping a car with jumper cables is one of those daunting tasks we’re forced to face when it alone. It’s necessary to know how to jump-start your car properly to avoid damaging and/or injury. The myth that jumping a car is a simple, easy feat is untrue for everyone. We at SENFLY aim to help you jump start your car the right way to avoid the wrong circumstances. Let’s discuss mistakes to look out for, along with the proper procedure of how to jump-start a car alone. 


The biggest mistake that one makes when 12V JUMP STARTER a car alone is that they incorrectly connect the jumpers cables to the battery terminals. When connected incorrectly the jumper cables cause a spark and have the potential of messing up the cars’ electronics, and even cause a battery explosion. The red jumper must be attached to the positive (+) terminal of the dead battery first. Next, the positive (+) terminal of the working battery should have the other red jumper connected to it. After that, connect the negative (-) terminal of the working battery to the other black jumper cable. Finally, connect the black jumper cable to a piece of metal on the dead car; avoid the negative terminal on the dead battery since the spark could cause the battery to explode. 


Fortunately, there are multiple easy steps to safely jump-start your vehicle alone. 

First, ensure you have a set of jumper cables readily available to use. Ensure that the jumper cables are clean, and do not look worn. Ensure the working battery is directly next to the car with the dead battery, or close enough for the jumper cables to reach both vehicles; however do not allow them to be close enough to touch. Begin by connecting the red jumper cable to the positive (+) terminal of the dead battery. Then, connect the other red jumper cable to the positive (+) terminal of the working battery. After that, connect the negative (-) terminal of the working battery to the other black jumper cable. Finally, connect the black jumper cable to the piece of metal of the dead car (e. g. Bolt, or an unpainted part of the car’s engine). Start the working car and let it run for a couple minutes. If the dead car does not start, allow it to continue running for more time, then try again. If it does not start it may not be the battery that is the problem. After the car is running, disconnect the jumper cables in reverse order: disconnect the black jumper cable from the dead car first, then from the working car; disconnect the red jumper cable from the working car second, and the dead car last.
