How to start a car if the battery is dead? How to start a car if the battery is dead in the cold?

The battery is one of the most common sources of vehicle problems. The generator can fail due to poor contact in the wires and terminals, and as a result of a long stop it is simply discharged. There are other reasons for the failure of the battery - for example, a broken bank in the composition of the battery inevitably leads to discharge. Fortunately, experienced motorists have developed many ways to get out of problem situations. Especially drivers who are at risk of “breaking down” on the highway and in severe frost, you need to remember how to start the car if the battery is dead, and the nearest car service is a few kilometers away.

Plant "with a push"

The first thing any experienced driver will remember is push starting. Before the operation, you need to make sure that there are no obstacles in front of the vehicle, and even better if the movement will be carried out from the hill. In general, you need to figure out how to start the car if the battery is dead, so that less effort is expended and maximum efficiency is ensured - a clean track and a few assistants will help you cope with the task.

You should start by activating the ignition, after which the sequence is as follows: fuel enters the system, shifting to second gear, depressing the clutch, accelerating the car to 10 km / h. When the minimum is reached, it is necessary to release the clutch and add gas. If the start was successful, you should squeeze the clutch and check the operation of the internal combustion engine.

If the car is with automatic transmission?

With the mechanical version, everything is quite simple, but in the case of automatic transmission, you need to take into account some of the nuances of how to start the car if the battery is dead. The automatic transmission assumes the presence of one oil pump, therefore, when the engine is not running, it is not necessary to wait for the corresponding pressure from it. In this regard, it is recommended to remove the belt from the drive, and wrap the pulley with a suitable cable or rope. Then, with the ignition on, you need to pull the rope - the box should be switched to "neutral" or to "parking mode". As a rule, this method only works with motors whose volume does not exceed 1,500 cubes, but this is better than nothing.

Towing

The principle of starting the engine by towing is a bit similar to the "push" method. But for its implementation, it is necessary to have a towing cable and, in fact, a second car, which will provide sufficient traction. This is an elementary help and every driver should know how to start the car if the battery is dead by means of a cable and a random colleague.

Now to business. In the first position, the gearbox must be "neutral" and the ignition off. Upon reaching approximately 20 km / h, work can begin - the ignition is turned on and the clutch is squeezed out, after which it is necessary to activate the first or second gear. Further, the clutch is slowly released - at this moment the internal combustion engine should start. Upon successful start of the engine, the clutch is pressed again and the procedure ends.

Unfortunately, towing methods do not always provide the appropriate result in winter. Therefore, the answer to the question of how to start a car if the battery is dead in the cold should be sought in other means.

How to "light up" from another car?

To meet a car with a battery charging kit on the road is a real success for a motorist who has been let down by a battery, and the weather conditions are not the best. In this case, it is necessary not only to understand how to start the car if the battery is dead, but also to know the technical nuances of the event. For example, the cross section of the wires should be 1.6 cm 2, and the length should be about 2 m. In addition, the presence of pliers is mandatory.

Many in such operations are confused by the rules for correlating contacts. In fact, everything is simplified thanks to the colors of the wires. There is no fundamental difference in the sequence of connecting the "plus" and "minus", although it is more convenient to complete the last one, which is connected to the battery. The main thing is to prevent closure. By the way, if a spark occurs during the connection process, this is not scary and even normal.

Immediately after connecting the wires, do not wind the starter. It is necessary to give some time to charge, and then deal directly with the launch - by the way, it will be provided by two batteries at once. The advice of professionals on how to start a car if the battery from another car is dead, they note that this operation does not pose any particular danger to the “donor” - the degree of load is within the permissible range.

When the engine starts, do not disconnect the wiring. It is recommended to give the battery some time to recharge so that you do not have to repeat what you have done if the battery does not fulfill its function.

Depending on the condition of the battery, the procedure can become not only pointless, but also dangerous. You need to know how to start the car if the battery is dead, through the cigarette lighter and without the risk of an explosion. The fact is that a specific smell and excessive heating indicate its internal problems. This may be the electrolysis of water, which resulted in the release of oxygen and hydrogen. This mixture may explode on contact with a spark. Also, lighting is undesirable if electrolyte leaks - this usually happens due to damage to the outer shell of the battery. No less dangerous is another malfunction - damage to the contacts between the banks.

The lighting procedure is justified if the battery is discharged for natural reasons. For example, it was left at night with the heating working. The potential performance of the battery can be confirmed by the starter, when turned on, the relay should click.

In frosty conditions

The best way to help a battery perform at low temperatures is to prevent possible freezing problems. If it is possible to leave the battery overnight at home or in the garage, it should be used. In extreme cases, it is worth warming up the engine a few hours before the trip. In such situations, the problem of how to start the car if the battery is dead in the cold disappears by itself. If it was not possible to prepare for a frosty morning, then means of prompt assistance to the battery should come into play. These include flashing high beams and starting electrical equipment - these measures should “wake up” the power source. If there is 1-1.5 hours in stock, then it makes sense to heat the battery at home in warm water.

Autochemistry to help

Along with the traditional methods of activating the battery, there are a lot of modern and even specialized tools. Manufacturers of automotive chemicals produce lines of additives specifically focused on quick start-ups. They should be poured into both the fuel system and the carburetor. These measures facilitate the process of starting the engine and, in general, the operation of related components and systems. Especially such preparations will be useful for those who are looking for ways to start a car if the battery is dead, in winter and without outside help. Also, do not ignore additives with a preventive effect: they extend the battery life, reduce wear, increase capacity, minimize the time to replenish the charge, and also make it easier to start in cold weather.

How to start a car alone?

It must be said right away that it is almost impossible to do this on an empty track. In theory, you can try "with a pusher" or with the help of a jack by spinning the wheel, but such methods work only in isolated cases. Therefore, the question of how to start the car if the battery is dead, one, rather, can be attributed to garage conditions with the presence of a charging device. The connection is made first to the battery, and then to the network. The reverse sequence can lead to damage to the on-board electronics of the machine. Next, wait about 30 minutes. During this time, the battery will gain some energy for minimal operation, after which the engine can be started. At the same time, you should not turn off the start-charging device: this will unload the battery a little.
