How to 'borrow power' before the battery is dead

To start the car, but found that the battery is dead, presumably many people have encountered this situation. In this case, you need to 'borrow electricity' to start the car, so how to correctly 'borrow electricity' is also a driving skill. Although this operation is not complicated, there are some areas that require special attention. In short, all you need is the right equipment and the right steps. The correct equipment is the battery auxiliary cable and a car that is operating normally.  The correct operation steps are as follows:   1. Drive the car that is operating normally to the front of the faulty car, generally taking the position relative to the front of the car. Put the car in parking block P and pull up the handbrake. Note: The two vehicles are as close as possible to facilitate operation. But it must be ensured that there is no contact between the two car bodies.  2. Turn off the engines and ancillary electrical equipment of the two cars, that is, all power-consuming equipment such as car lights, radios, air conditioners, and fans.   3. Open the hoods of the two cars, find the battery and the positive and negative poles of the battery, and make sure the electrodes are clean. Generally, the positive electrode of the battery is marked with '+' and the negative electrode is marked with '-For batteries that are not clearly marked with '+' and '-NEG (Negative) stands for negative electrode. Pay attention to the cleanliness of the electrodes. Poor electrode contact is one of the main reasons for starting failure. 4. Clip one end of the positive electrode (with a red clip) of the battery auxiliary cable to the positive electrode (+) of the faulty car battery, and clamp the other end to the positive electrode (+) of the battery in a normal operating car; then connect the negative electrode (with a black clip) of the auxiliary cable Clamp one end of the clamp) to the negative (-) of the battery of the normal car; finally, clamp the other end of the negative cable to the engine shell of the malfunctioning car.   Note: During the whole process, it is necessary to ensure that the positive cable and negative cable clips do not touch, to prevent damage to the battery caused by a short circuit. The best place for the negative cable to connect to the faulty car is the engine casing, as far away as possible from the faulty battery. If you are unsure of the engine location, you can use a thick metal frame, or the negative pole of the battery. But do not connect it to the car shell or any parts that may rotate. When connecting the clip of the auxiliary cable to the battery electrode, you can hold the clip and shake it left and right several times to ensure good contact between the cable and the electrode.   5. Start the car that operates normally, and step on the accelerator pedal to increase the engine speed.  6. u200bu200bStart the faulty car, if it still can't start, check if the contact is bad. 7. Once the faulty car starts to start, disconnect the auxiliary cable in the reverse order of step 4 (remove all wires in sequence, otherwise it will cause trouble if short circuit is caused), first loosen the cable clamped on the negative pole of the battery, and then Loosen the cable connecting the positive terminal of the battery.   8. Drive a car with a battery failure and drive for at least 20 minutes to ensure that the battery has enough time to charge. It is recommended to check with a car dealer or a knowledgeable friend afterwards.  Other precautions:  1. If you find any cracks in the casing of the faulty battery, do not borrow power, replace the battery or ask a technician for help.  2. If the faulty battery is found to be frozen, do not skip charging, as the battery may explode.   3. If you find white/green/cyan powdery crystals near the electrode of the faulty battery, clean the electrode with a wire brush first. If necessary, use a steel file to file several times on the side of the electrode after cleaning to ensure good contact between the cable clamp and the electrode. This situation usually indicates that you need to change the battery.   4. Borrowing electricity consumes a lot of battery. If you still can’t start the car with the correct operation, it is best to ask a professional technician for help instead of trying blindly.
