What to do if the car battery is dead and the car cannot start?
First, let's talk about how to start the car. Due to the presence of a hydraulic torque converter in models with automatic transmission, the gearbox and the engine are not rigidly connected, so you cannot use a push cart to start the car. In this case, starting can only be done with an external power supply. This external power supply can be that of a normal vehicle or an emergency starting power supply. The specific steps for connecting and starting the external power supply are as follows:
1. Connect the positive terminal of the battery of the rescued vehicle to the positive terminal of the rescue vehicle
3. After getting into the car, first remove the wiring in positive order, then negative.
First of all, for models with automatic transmission, you should not push the car to start it. It is recommended to carry a portable charger with the car. In case of emergency, you can use the portable charger to charge. , and connect the charger and battery. After the terminals are connected, set the charging parameters, start charging, then start the ignition after charging, and you can use it normally
In addition, there is a flying cable in the car . If conditions permit, you can ask for help from passing cars or relatives and friends, and find a normal car to come and help you. Use jumper cables to conConnect the positive terminal of the power-assisted car battery to the positive terminal of the power-assisted car battery, then connect the negative terminals of the batteries of the two vehicles, then turn on the power-assisted vehicle. to start the car. It should be noted that after starting the car, disconnect the negative cable first, then the positive cable.
Generally speaking, for models with automatic transmission, when there is no electricity, if you are not equipped with one, it is recommended to call the emergency number for help and let professionals come to the rescue. Of course, the vehicle must be inspected more frequently to prevent the occurrence of battery failure.
1. Use the charger to recharge, and it will be fixed when done!
2. Use the battery to mount the contact. After starting, do not turn off the engine. remove the mounted battery and drive on the road After a certaIn time, wait until the battery power reaches the rated voltage here.
What should I do if the car battery is dead and the car cannot start?
1. The manual transmission can be used to start the cart (scoot) or charge the battery. Or connect your jumper wire to other vehicles, let the vehicle's external power turn on, then start the vehicle.
2. The automatic transmission can only charge the battery. Or connect your jumper wire to other vehicles, let the vehicle's external power turn on, then start the vehicle.
3. The battery can be removed and taken to maintenance to be charged, or a special small transformer can be used to change the voltage and then be charged nearby (as the car voltage is usually 12 volts).
I hope to adopt it. THANKS! ! !
The car battery is exhausteded and cannot turn on. Is it okay to let it sit for a while?
Your car battery is running out of power and can't catch fire. is a common fault when using a car. If you encounter this problem, we can start this fault in several ways.car.
1. Use another car's battery to connect the battery and start the ignition. This is usually the preferred method and sometimes the only option. When connecting to the mains, do not make a mistake in the wiring order: the positive pole of the emergency vehicle → the positive pole of the faulty vehicle, the negative pole of the emergency vehicle → the engine ground. The disassembly order is reversed.
2. For manual transmission models, the trolley start method can be used. The specific method is: one person sits in the driver's seat, opens the door with a key, depresses the drive pedalclutch and shift into second gear, then someone else pushes the car. When the vehicle speed reaches more than ten kilometers/hour, the driver. quickly lift the car. The clutch pedal is used by the car to turn the engine, and the engine will start. However, the operation is somewhat difficult, so novices should not try it easily.
3. There is now an emergency jump start power bank that can be started directly by clipping it onto the battery. Its principle is actually the same as borrowing electricity from other vehicles, but it can only start the car once or twice, and it will be of no use if it does more.
4. Many insurance companies also offer emergency rescue services. You can call the service number of the insurance company you have insured and ask them to come to your rescue. But their speedis a bit slow and the distance is too far.
What should I do if the car battery is dead?
If your car battery is dead, the easiest and most common way to remedy a dead battery is to restart it. All you need to start your car is a set of jumper cables and another car with a working battery. Remember, if your car battery is cracked and there is visibly leaking acid, you should not try to start your car.
Signs of a dead car battery:
Slow engine starting: When you try to start your vehicle, the engine starts slowly and takes longer than normal to start. to start up.
Check engine light
Low battery fluid
Swollen and swollen battery case
Battery leak
p>
NOTE: If the battery begins to start and runstart your engine, but the car won't start again once you turn it off, the battery may be the problem. In this case, the alternator's job is to keep the battery running after it trips, but the battery cannot stay charged when the alternator shuts off.

Starting the engine can draw 100 to 130 amps, and idling the car for 15 minutes can reduce three to four amps. "?" If your idle time is only 15-20 minutes, the battery will never really charge. So every time you start it and leave it idle, the load gets lower and lower.
What should I do if the car battery won't turn on?
If negligence causes the battery to lose power, generally the battery will not "die" directly once other vehicles are "connected to backup", your vehicle mayto start up. After booting, let it start. the engine runs for a while or if you drive for a while, the battery will be activated and return to normal.
If the car battery is dead and cannot start, should I replace it with a new one?
p> Once the battery is discharged due to negligence, the battery will not “will” usually not die directly. Once other vehicles are “backup connected,” your vehicle can start. After starting, let the engine run for a while, or. drive for a while, the battery will be activated and return to normal.
What is the reason why the car battery has power but cannot turn on?
It may be that the battery voltage is insufficient does not mean that There is no power. The horn and lights can also be turned on, but the battery cannot get up and start themachine. The battery light stays on as long as the key is in the ON position before switching on the ignition.
1. Car battery voltage is low; Specific detection method: Use a three-purpose meter to test the battery voltage. If it is below 10V, replacement is recommended. If it's around 11V, use it reluctantly; prepare to replace it. 12V or more can be used;
2. Check to see if this is caused by carbon deposits; if the driving distance is about 20,000 kilometers, focus on checking and cleaning the throttle
3. . Check, test and replace spark plug;
4. Check the quality of the added gasoline;
5. Check the ignition switch; . Test the starter, fuel pump, sensors and other components related to the starting and fuel systems;
7. Furthermore, after switching onvoltage, do not start immediately, wait 30 seconds to 1 minute before turning on. ; see if there is any effect;
< p> Regardless of any of the above situations, please note that when the car cannot be turned on at the same time, be sure to wait 15 30 seconds before turning it back on. to protect the battery from electricity generation and extend its life.What to do if the car battery is dead and the car cannot start?
If the car is not driven for a long time, the energy of the battery will be gradually consumed, causing difficulties. at startup. The solution is: 1. Setting up If your car is equipped with a bonding line, or you can borrow a bonding line, you can borrow another car's battery to turn on your car, but this method is impossible, and most car owners won't do it themselves. Prseparate the wiring, and the operation process may also cause psychological barriers and some dangers for friends who do not understand electrical appliances or shy women. It should be noted that the positive pole is connected to the positive pole; the negative pole is connected to the negative pole. Don't put it the wrong way! Otherwise, the battery may be fried. If the electrodes are connected backwards, causing white smoke or a burning smell, the battery should be replaced. Another possibility is that the very low temperatures in winter in the north freeze the battery. If that's the case, you can't use wiring to save yourself. 2. Push cart to “maintain the combustion” If we don’t have tools around us, the easiest way is to use a push cart to help light the fire. However, pushing the cart requires several conditions: first, you need to make sure that itThere is still residual energy in the battery. If the battery is completely drained, pushing the cart will not help. Second, the push method is reserved for manual transmission models. , models with automatic transmission. The model cannot be started using a push cart, nor can it be towed with a tow rope (the trailer can only be towed with a tow bar. It can only be started by cable or towed up to a 4S workshop). with a flatbed rescue vehicle for repair. PackageThe principle of "pushing" the car is to use human force to push the car, and the kinetic energy reacts on the piston of the cylinder, forcing it to compress the gas in the cylinder and burn it. If everything else is normal, the generator will do it. charge the battery once started.
The car battery is dead and cannot start the fire. Do I need to replace the battery?
If uNegligence causes the battery to die, it usually runs out. will not “die” directly. It will be “connected” by other vehicles. After "electric rescue", your vehicle can start, let the engine run for a while, or drive for a while, the battery will be activated. and return to normal.
Automatic starting and stopping of vehicles can provide power to other vehicles. When the vehicle is powered on, it is best to put it into starting state. In this case, the vehicle's electrical devices are powered by the generator, which does not need to consume energy from the battery and will not damage the start. stop the battery. At the same time, when powering on, the positive and negative poles of the battery should be connected correctly, not reversely, positive to positive, negative to negative, otherwise it will cause a short circuit, damage the components élvehicle electronics, etc. and in severe cases, damage the engine computer board, etc. Causing unnecessary maintenance costs. Maintenance of the start-stop battery is the same as that of the non-start-stop battery. It is best not to turn on the stereo and CD when the vehicle is parked for a long time. It is best to install original electronic components. to ensure that the vehicle does not leak. If the vehicle is parked for a long time, when the car is not used for a long time, it is best to remove the negative pole of the battery to reduce battery power consumption. Battery. Regularly check the working status of the vehicle generator, check the battery status, charging and discharging status, and charge it if necessary, which can effectively extend the starting time of the blackout bottle.
