Is it possible to start a car if the battery is dead: all methods

Most often, problems with the battery occur in winter, as it discharges faster in the cold. But the battery can be discharged due to the parking lights not switched off in the parking lot, other electricity consumers. In the event of such a situation, you do not need to panic. There are several proven ways to start a car if the battery is dead.

How to start a car with a flat battery

Before you start solving the problem with a dead battery, you first need to make sure that it is because of it that you cannot start the car. Factors indicating that the battery is dead:

• the starter turns very slowly;
• the indicators on the dashboard are dim or not at all;
• when the ignition is turned on, the starter does not turn and clicks or crackling are heard.

There are different ways to start the car with a discharged battery.

Start-charger

It is possible to use a network starting-charger when starting up any cars, regardless of whether they have a mechanical transmission or an automatic one. How to use it:

1. They connect the ROM to the network, but do not turn it on yet.
2. On the device, switch the switch to the "Start" position.
   

   Starter charger can be used when starting any car
3. The positive wire of the ROM is connected to the corresponding battery terminal, and the negative wire is connected to the engine block.
4. They turn on the device and start the car.
5. Unplug the ROM.

The disadvantage of this option is that you must have access to the mains in order to use the network starting-charger. There are modern autonomous starting-chargers - boosters. They have a powerful battery, which, despite its small capacity, can instantly deliver a large current.

Due to the presence of batteries, such a device can be used regardless of whether there is access to the mains.

It is enough to connect the terminals of the booster to the battery, and you can start the engine. The disadvantage of this method is the high cost of the device.

Lighting up from another car

This solution can be implemented when there is a donor car nearby. In addition, you will need special wires. You can buy them or make your own. The cross section of the wire must be at least 16 mm², and you also need to use powerful crocodile latches. Lighting order:

1. A donor is selected. It is necessary that both cars have approximately the same power, then the characteristics of the batteries will be similar.
2. Cars are placed as close to each other as possible. This is necessary so that there is enough length of wires.

3. The donor is jammed and all electricity consumers are cut off.
4. Connect the positive terminals of both batteries together. The minus of a working battery is connected to an engine block or other unpainted part of another car. Connect the negative terminal away from the fuel line so that a spark does not start a fire.
   

   The positive terminals are connected to each other, and the minus of a good battery is connected to the engine block or other unpainted part.
5. They start the car with a dead battery. It needs to run for a few minutes for its battery to charge up a little.
6. Disconnect the wires in reverse order.

When choosing a donor, you need to pay attention to the capacity of its battery to be greater and equal to that of the battery of the reanimated car.

Increased current

This method should only be used in critical situations as it will shorten the battery life. In this case, the dead battery is recharged with an increased current. The battery does not need to be removed from the car, but it is recommended to remove the negative terminal so as not to damage the electrical appliances. If you have an on-board computer, it is imperative to remove the negative terminal.

You can increase the current by no more than 30% of the battery characteristics. For a 60 Ah battery, the maximum current should not exceed 18A. Before charging, check the electrolyte level and open the filler caps. Enough 20-25 minutes and you can try to start the car.

From a tug or pusher

Towing can only be carried out with a manual transmission. If there are several people, then the car can be pushed or it is connected with another car using a cable.

Procedure when starting from a tug:

1. With the help of a powerful cable, both cars are securely connected.
   

   Only cars with a manual transmission can be towed.
2. Gaining speed of the order of 10-20 km / h,
3. On a towed vehicle, engage 2nd or 3rd gear and smoothly release the clutch.
4. If the car starts up, both cars are stopped and the tow rope is removed.

When towing, it is necessary that the actions of both drivers are coordinated, otherwise an accident is possible. You can tow a car on a flat road or down a small hill. If the car is being pushed by people, then it is necessary to rest against the racks so as not to bend the body parts.

Normal rope

This option is suitable when there are no cars or people nearby. It is enough to have a jack and a strong rope or a towing cable about 4-6 meters long:

1. The car is fixed with the parking brake, and additional stops are also placed under the wheels.
2. Jack up one side of the machine to release the drive wheel.
3. Wrap the rope around the wheel.
   

   The rope is wound tightly around the raised wheel.
4. Include ignition and direct transmission.
5. The rope is pulled sharply. The car should start while spinning the wheel.
6. If it does not work the first time, the procedure is repeated.

In order not to get injured, you must not wind a rope around your hand or tie it to a disc.

Folk methods

There are also popular methods by which drivers are trying to restore the performance of a dead battery:

• installing the battery in a basin of warm water or near a heater. This is an inefficient method that allows you to increase the battery voltage quite a bit. Its frequent use leads to an earlier failure of the battery;
  

  Putting the battery in warm water allows you to slightly increase its voltage.
• the imposition of a heating cover on the battery. This is usually done in winter to reduce battery drain. Do not expect a positive result, since the cover itself does not heat up and the battery capacity will not be restored;
• application of wine. Wine is poured into the battery. Alcohol reacts with the electrolyte, which leads to an increase in voltage and the car can be started. This method can only be used once, after which the battery will have to be thrown away. If you use wine, it is better dry, since there is practically no sugar in it.

Some craftsmen managed to start the car with the help of a telephone battery. True, this required not one phone, but a whole hundred 10-ampere lithium-ion batteries. The fact is that the power of the battery of a phone or other gadget will not be enough to start the car. In practice, this method is not very profitable to use, and you are unlikely to find the required number of batteries from mobile phones.

LIFE HACK - how to start a car if the battery is dead.

To avoid problems with a dead battery, you must constantly monitor its condition. In the parking lot, it is necessary to turn off the dimensions and appliances that consume electricity. If, nevertheless, the battery is dead, then you need to adequately assess the situation and choose one of the available methods that will allow you to start the car.
