To start the car, I found that the battery is dead, I have to have some people have encountered this situation. In this case,“Borrow”Let the car launched, then how to correct“Borrow”It is also a trick to drive. Although this operation is not complex, some of them need to pay more attention. In short, what you need is the correct device and the correct steps. The correct device refers to a battery-aided cable and a normal car.
The correct steps are as follows:
1. Operate the normal car to the front of the fault, generally take the relative position of the head. Place the car in the parking block P and pull the handbrake. Note: The two cars should be as close as possible to facilitate operation. However, it must be ensured that the two cars have no contact.
2. Close the engine of the two cars and an affiliate electrical equipment, that is, all power consumption appliances such as headlights, radios, air conditioners, and fans.
3, open the hood of the two cars, find the positive and negative poles of the battery and the battery, and ensure that the electrode is cleaned. In general, the positive electrode standard of the battery is“+”The negative pole“-”It is easy to identify. Not clearly indicated“+”,“-”The battery can be assigned to identify the positive and negative electrode: * The electrode lead connector is used as a positive electrode; * The electrode of the protective cover is a positive electrode; * POS (position) represents the positive electrode, NEG (Negative) indicates the negative electrode. CAUTION View the degree of cleaning of the electrode. Poor electrode contact is one of the main causes of failure failure.
4, clamp one end of the positive electrode (with red clip) of the battery assist cable to the positive electrode (+) of the faulty car battery, the other end clipped to the positive electrode (+) of the normal car battery; then the anode of the auxiliary cable (black One end of the clip is clipped to the negative electrode (-) of the normal car battery; finally, the other end of the negative electrode cable is sandwiched on the engine housing of the faulty car.
Note: In the whole process, it should be ensured that the pinch of the positive electrode cable and the negative electrode cable does not contact to prevent damage to the battery. The connection position of the negative electrode cable is preferably the engine housing, as far as possible to the location of the faulty battery. If you are unable to determine the engine position, you can use a thick metal frame, or the negative electrode of the battery. However, do not pick it up on a car housing or any possible rotating component. When the clip of the auxiliary cable is connected to the battery electrode, you can hold the left and right swaying a few times to ensure that the cable and the electrode have good contact.
5, start the normal car and step on the speed of the accelerator pedal.
6. Start the fault car, if you still can't start, check whether you have poor contact.
7. Once the failed car begins to start, disconnect the auxiliary cable according to the opposite step 4 (remove all wires, otherwise it will cause a short circuit to have trouble), first loosely open the cable, the battery is connected, then Loosen the cable connecting the battery positive electrode.
8. Driving a battery failure, driving for at least 20 minutes, ensuring a sufficient charging time. I suggest that I will find a car or a friend who knows it.
1. If you find that the faulty battery housing has cracks, don't borrow it, change the new battery or ask the technician to help.
2. If the faulty battery is found, do not skip charging, the battery has the possibility of explosion.
3. If the faulty battery electrode is found to have a white / green / cyan powdered crystal, the electrode is first used. If necessary, the side of the electrode can be used in the side of the electrode after cleaning, to ensure good contact of the cable steel clamp and the electrode. This situation usually indicates that you should change the battery.
4. Borrowing electricity to consume the battery. If your operation is still unable to launch the car, it is best to ask a professional technician to help, but don't try it.
