![]() ![]() With the potential risk of physical harm and the enormous costs involved in replacing and reprogramming the ECUs, operating a car battery to jump-start without proper knowledge is not a good idea and can land you heavy repairs if you are not careful with the steps.Ī car battery has two terminals namely positive and negative. If it is, it could lead to an explosion.Īlways start with the bad battery first as it does not have a charge and is safe to operate.ĭon’t leave anything under the hood when starting the vehicleĪfter charging the battery, drive the car for 15-20 minutes to let the alternator fully charge the battery. Remove or turn off accessories and electricals such as headlights, radios, and turn signals as the surge in power will surely short them outĬheck if the fluids aren’t frozen or the battery isn’t warped and bent out of shape. Verify if the voltage is correct using a multimeter, if the voltages do not match it could spell serious problems for both the batteries. Make sure the terminals aren’t dirty and if they are clean them with a dry cloth. Turn both vehicles off before locating the battery Some newer cars do not allow jump-starting and can even void your warranty so be sure to read the warranty conditions as well. ![]() Some cars may use lugs instead of clamps while some vehicle may require certain precautions as removing fuses or turning on defroster. Other Things To Consider When Jump Startingįirstly look in the owner’s manual for any precautions or know-hows before attempting to jump-start. The bad battery can even explode and cause damage to the people around. If the battery is in poor condition or has not been used in a while, jump-starting with cables reversed can worsen the situation. The surge in power will have a negative effect on the alternator and may even cause irreparable harm. The vehicle charging the bad battery might also suffer mechanical damage. Whether you have an explosion or not depending on the other factors and the condition of the batteries, you will however surely find blown-up fuses and wires in your vehicle. Additionally, it may spill to damage parts in the vicinity and you might not be able to do anything about it. The battery will be warped as the acidic fluids inside will boil from the extreme heat produced in the reaction. the extreme heat produced will quickly melt the insulators on the jumper cables, clamping them forever on the battery which will be next in line as the plastic top will melt and bend. With an instant surge of electricity, the first to face the wrath and the consequence of an experiment would the jumper cables. Needless to say, it will not be tolerated well by the system or the components within and depending on certain factors will incur damage that is mostly going to be severe and irreparable. If the positives and negatives are switched, the battery will try to compensate and make the negative 12 volts into a positive charge resulting in a huge surge of power and an enormous amount of heat to be produced. The cable on the positive terminal uses +12V while the one on the negative side uses -12V. ![]() Each terminal of a car battery uses 12V of current with positive and negative orientation. When jump-starting a car there are certain caveats to charging your vehicle as the transfer of energy from one battery to another is not as simple as it seems.Ĭonnecting the battery terminals in reverse can cause serious damage to the battery itself, the electrical components, and even to yourself.
