The car does not start: possible causes and methods for their elimination. Bringing the battery to a usable condition - using external sources

18.04.2019

The battery can let the driver down at the most inopportune moment. This is especially true for car owners who do not monitor the car and ignore the periodic check and maintenance of the on-board power source. Let's figure it out. In this case, there are several ways that we will consider with you. We will also find out the reasons and signs that the battery is low.

To begin with, let's figure out how to determine that the reason for stopping the car and refusing to start is in the onboard battery. In this case, the driver observes the following phenomena.

If you can't start and hear all of the above sounds, then the problem is with the battery.

Many in this case are wondering why the battery sat down so quickly. The reasons may be different. First of all, it is worth considering that the battery has the peculiarity of slowly discharging even during idle periods. In addition, your battery may have exhausted its resource, batteries usually last no more than 4-5 years. Also, the cause may be a problem on the part of the generator, which does not charge the battery while driving. Another reason may be a hard frost or headlights not turned off during the downtime.

In order not to solve the issuehow to start a car if the battery is deadbattery should be checked regularly. Check the electrolyte level and ensure that there is no complete depletion of the charge.

How to start a car if the battery is dead: 6 options available

Let's move on to the practical part. What exactly needs to be done by the driver to try to start the car with a dead battery. In this case, we will provide attention to six available methods, which one to use depends on the situation.

This . This is a special device designed to help in such a difficult situation. The only condition is that a source of electricity is needed, that is, the device must be connected to the network.

Then the mode switch is set to the "Start" position. In this case, the wire with + charge is connected to the + terminal of the battery, and the wire to the block car engine next to the starter. Then you need to turn the ignition key and wait until the car starts completely. After that, you can disable the ROM.

This approach is applicable to any type of transmission. Regardless of whether it is automatic or mechanical, the ROM will allow you to quickly and painlessly start the engine.

This method is also very effective, but there are small nuances. Today it is not so easy to find a driver who is ready. This is due to the fact that an unsuccessful attempt can damage the automation of the “donor” car, the repair of which will cost a large amount.

But if, nevertheless, a donor is found, then you will need more wires for lighting and a wrench for 10. You should also carefully choose a donor. The battery capacities of the two vehicles must match or be close to each other.

The car is placed "face" to each other, but without contact.
The “donor” engine is turned off, and the negative terminal is removed from the recipient.
Be sure to observe the polarity so as not to harm the electronics of the vehicle. Connect the positive terminals together.
Then we connect the minus to the donor and only then to the recipient.
Start the donor engine to add energy to the battery of the "sick" car.
After 5-7 minutes, start the recipient car and let it run for a while to accumulate its own charge.
Disconnect the terminals in reverse order.

Over current

Let's figure it out how to start a car if the battery is deadwith increased current. The battery may not be removed, but if the vehicle has on-board computer and fine electronics, it is worth disconnecting the negative terminal.

The current increases by no more than 30% of the established norms. That is, a 60 Ah battery allows a current of up to 8 amperes. This method is only suitable for good level electrolyte. Fill plugs must be opened.

After 30 minutes of such charging, the car will be able to start, but you should not abuse it. It significantly reduces battery life.

To perform this method, you will need a cable and an assistant car that will tow a vehicle that is unable to start on its own. Cars are coupled with a cable and accelerated to a speed of 15 km / h. On "sick" vehicles, turn on third gear and slowly release the clutch.

Before implementing the method, it is important to coordinate actions with the second driver in order to prevent mechanical damage transport. As soon as the second car is started, the cable can be disconnected.

lithium battery

The method is not the most reliable, but nevertheless it has a place to be. For minimal recharging, a relatively capacious battery is used. lithium battery(from a laptop, phone, camera). Charging takes about 20 minutes. You can connect directly or through the cigarette lighter.

This is the last way we want to talk about. The crankshaft cranking device can be seen in old films, where the driver started the truck by turning the z-shaped curved piece of iron.

Modern transport not adapted for such tools, but the method itself is still applicable. For implementation, you will need a jack, about 6 meters of a strong rope. Raise driving wheel using a jack, wind a rope around it, turn on the ignition and direct transmission. Pull the rope to spin the wheel as far as possible.

You can start the car if the battery is dead, and one, without outside help. Driving practice has developed methods when an external power source is not even required to spin the starter. In addition to the well-known pusher or tug, this is also a rarely used method of spinning the drive wheel with a rope.

In addition, everyone knows that you can light a cigarette from another serviceable battery, but not everyone knows how to do it correctly so as not to harm a voluntary assistant. Each method has its own characteristics.

1 Bringing the battery to a usable condition - using external sources

An unpleasant situation when the battery is dead can happen anywhere. If this happened in the garage, then there is a 220 V outlet, into which a charger or starting device is connected. They are usually used for many hours. If you need an urgent departure, they are applied within a few minutes. After all, it does not require full recovery battery, and bringing it to a condition suitable for starting the engine.

In the field, they usually look for another way out, because connecting to the network is impossible. They are waiting for someone who will agree to give a "light" from his battery, to stretch in tow, to push. But progress does not stand still. Modern starting devices - boosters are produced. They have a battery and electronics that can give the battery enough energy to start the engine.

Emergency Recharging - used as a last resort

You can detect a dead battery on a car at any time, especially in winter. It is worth overlooking his condition, and in the cold, a battery that has run down in the morning will not want to turn the starter. If the car is in the garage, there is Charger then it comes to mind to apply it. But the process is too slow if the recommended charging current is used.

IN emergency cases when you need to leave urgently, apply fast charging, including the Boost mode provided on many devices, or adjust the amperage manually. In 15–20 minutes, the battery will take a charge sufficient to start the engine. The parameters should not exceed the normal mode by more than 30%. If, for example, the battery is 55 A / h, a current of 5.5 A is recommended, and for fast charging maximum permissible value 7.15 A.

The procedure is performed in the following order:

the terminals are removed, the battery remains in place;
charger wires are connected;
the current is set;
the charger is switched on for 20 minutes.

In banks, do not forget to open the plugs, because with increased charging, an increased amount of gases is formed.

This method is used very rarely, only in case of emergency: there is a high risk of damaging the plates from frequent use.

Starting the engine using a starter-charger

Not everyone has such a device, but if you have one, you can always solve problems with the car with guarantee, even when the battery is completely dead. It will take very little time - only 5 minutes. The device not only recharges the battery, but also helps to turn the starter.

Each ROM that is certified and officially sold has detailed instructions in Russian. It contains detailed information about starting the engine. It is highly recommended to use it: the device operates under voltage, which is a mortal danger to humans. We will give generalized information for the safe use of the starter-charger in case the manual is lost.

When starting the engine with a starting device, wires are connected to the battery using special terminals - alligator clips. The plus is connected first, then the minus to insure against short circuit in case of accidental contact with the ground of the positive terminal. Install optimal parameters charging current: 15–20 A. The battery voltage is monitored all the time, depending on its condition. When charging, the density of the electrolyte increases, the internal resistance decreases and the battery capacity increases.

When the voltage at the terminals reaches 15 V (usually takes up to 5 minutes), start the engine with a starter and turn the flywheel. The ROM is not turned off, winning starting power up to 300 watts. If the car does not start on the first try, repeat the process. This happens extremely rarely, perhaps the reasons are not in the battery. After a successful start, turn off the device to avoid overcharging.

Restoring battery power with a portable device

The industry produces miniature starting devices - boosters, which allow for 20 minutes to restore the battery capacity to a level sufficient to start the engine. They have lithium-polymer current sources, comparable in capacity to three smartphones. They do not really believe in the effectiveness of such devices, the reviews are contradictory. I guess it all depends on the quality.

Such a charger does not require connection to a 220 V network due to the built-in lithium batteries. It is convenient to take it with you on the road and, if there was a problem with starting the engine in a deserted place, such a device will always help out. You don't even have to get out of the car: the device is plugged into the cigarette lighter, and after 20 minutes you can move on.

The most comfortable to use automatic boosters. They are able to independently assess the condition of the battery, set the strength of the charging current and voltage. After connecting to a car battery, its serviceability and type are determined. If everything is in order, as indicated by the inscription on the display, select the mode. If an emergency start is necessary, a quick one is installed.

The most advanced devices of this series are capable of conducting normal charging and desulfation of the plates. Universal devices are compatible with batteries that have different level operating voltage and capacity from 20 to 300 A/h. They are protected against incorrect connection, overheating and short circuit.

Casting car battery to a condition suitable for starting the engine does not mean that it has fully recovered. In order not to resort to such actions in the future, you should drive for a long time at a good speed. Then the battery will be charged by the generator. Better to use special device and slowly restore the capacity to the required parameters.

2 Starting another car from the battery - correct and safe actions

Happen on the road different situations, and should be prepared to accept or provide assistance from other drivers. Not everyone is ready to stop, but when such a person is found, the easiest way is to light it from his battery.

Motorists must know the sequence of actions so as not to harm the transport of those who want to help. The procedure seems simple, but without special knowledge it can be dangerous.

When lighting is the only way to start the car

Towing or pushing the machine, especially when it is heavy, is not always possible. Using the method of spinning the drive wheel with a rope is sometimes impossible: not everyone carries it in the trunk. To light a cigarette from someone else's battery, which is well charged, is the most reliable and fast way launch in an emergency.

This option is especially relevant in the following situations:

a broken car of great weight, and it is impossible to start it in another way;
in the trunk there are wires for lighting;
when you need to start cold engine in winter;
The breakdown caught on the track, when the only assistant was the driver of the stopped car.

There may be other situations where no other option is available. Therefore, the driver must understand the intricacies of the process. It's not just about starting your engine. It is required not to harm the donor: not to spoil the electrical system, not to plant his battery.

Features of the process in an emergency

Not everyone knows how to start a car from someone else's battery. Therefore, you should learn and remember how to act in such a situation. Then the possibility of damaging the car of a person who agreed to help is excluded. The process will take a few minutes and everyone will continue on their way.

The proposed algorithm describes all the subtleties:

cable is used for high voltage with crocodile clips on each end;
the donor car becomes the front to the broken car, the hoods of both rise;
the ignition is turned off, and wires are pulled between the batteries;
the positive contact is connected to the same one on the donor battery, the negative contact is connected to the same terminal or the mass of the broken car;
the engine of a working machine starts.

Then they start the stalled car. There are tips to wait 20 minutes with the wires connected without starting the engines. If you follow these recommendations, the donor battery will be discharged. A dead battery begins to quickly take on the voltage of a good one. The result is two cars that need help.

Act quickly and accurately. After starting the engine volunteer assistant launch yours right away. They wait half a minute for the battery to recharge a little, and remove the wires. It remains to thank the savior and continue the journey. The motor is not turned off for 30 minutes or more, so that the generator gives a little charge.

When they get home, they bring the battery back to normal using special devices.

3 How to start a car from a pusher or tug

Every driver should be able to start the engine in this way. This is useful not only when the battery is dead, but also in a number of other cases: the starter, wiring, ignition switch are faulty.

You will need third-party help: a car to stretch in tow, or assistants to push. Sometimes one person is enough, and under certain circumstances, you can handle it alone. It all depends on the weight of the vehicle, the condition of the road and engine, as well as physical health.

Action algorithm

When a force is found that can move the car, both cars are coupled on a tow cable or rope. The driver gets into the passenger compartment, turns on the ignition and sequentially performs certain actions:

depresses the clutch and engages second gear (do not try another);
gives a signal about the beginning of towing or pushing;
when a speed of about 5 km / h is reached, it releases the clutch;
a little gassy, and serviceable engine sure to grab;
signals the front car, puts the gear in neutral.

The speed at which the engine starts depends on many factors. The serviceability of the ignition system is in the first place: the condition of the candles, contacts, advance angle. In summer, it even starts up in this way cold car who stood overnight on the street. In winter, starting from a pusher is almost impossible, except perhaps from a tugboat. hot car starts with one push, a few meters and a speed of 2 km / h are enough.

Is it possible to start the engine from the pusher alone?

This seems realistic if two conditions are met. First: the presence of a flat area or a slight slope downhill. Second, the engine is warm and a bad battery is the only reason the car won't start. There are no signs of other damage.

The main difference from the method when there are assistants is in the following points:

more acceleration required;
disperse to neutral gear with the ignition on;
pushing while at the open driver's door to quickly jump on the go;
squeeze the clutch, turn on second gear and abruptly throw the pedal;
step on the gas quickly.

With this option, a quick reaction is required in order to have time to jump into the car and complete all the actions until it loses momentum. Act deliberately, thinking through the possible consequences. The acceleration path must be free from people, vehicles and foreign objects.

When not to use this option

When the car suddenly stalls, they try to start it in any way, including from the pusher. Sometimes this does not lead to anything, because the reason is not in the battery. It is not always possible to find a place to accelerate the car, especially on busy city streets.

There are circumstances when it will not be possible to start from the pusher:

an automatic transmission is used;
the electrical system is faulty;
Unusual sounds are heard from the engine.

When three or four attempts in a row have been unsuccessful, do not try again. The reasons lie in other faults. The car should be towed or a tow truck called and then deal with the breakdown.

It must be remembered that starting from a pusher is an emergency method that can harm the gearbox and engine. Therefore, they immediately eliminate the malfunction and do not abuse it in this way.

4 A jack and a rope help - one person can handle it

The method is not very simple, but it will help out if there is no one to wait for help. One caveat - only applies to cars with manual transmission. You will need things that should be in the trunk: a jack and tow rope. The latter may not be, a rope 2–3 meters long will do, more is better.

They operate like this:

tighten parking brake, stones or stops are installed under the wheels;
using a jack, one of the drive wheels is raised;
include third gear and ignition;
tightly wrap the rope around the raised wheel and pull sharply or run back.

You can repeat several times if it did not work out from the first. When the engine is running, it is not turned off. Shift into neutral and lower the car. You should be careful and avoid fatal mistakes. The rope is in no case tied to the disk and not wound around the hand. When the engine starts and the tug wraps around the wheel, serious injury can occur.

5 Debriefing

When a person gets into an unpleasant situation with a car, he tries to start it accessible ways. Use only those that will not harm the machine. At emergency on the road, as the most acceptable options, starting with a cigarette lighter and with a pusher are recommended.

In the garage, you can occasionally use emergency charging or a starting device. As for the booster, few can afford to buy it. Cheap devices are just toys. It should be remembered about possible consequences emergency start, especially if you act ineptly. Sometimes you have to resort to emergency methods, but it is better not to allow similar situation. If it happened, the reasons are immediately eliminated.

X Do you still think that car diagnostics is difficult?

If you are reading these lines, then you have an interest in doing something yourself in the car and really save because you already know that:

Service stations break a lot of money for simple computer diagnostics
To find out the mistake you need to go to specialists
Simple wrenches work in the services, but you can’t find a good specialist

And of course you are tired of throwing money away, and it’s out of the question to ride around the service station all the time, then you need a simple AUTO SCANNER ROADGID S6 Pro, which connects to any car and through a regular smartphone you will always find a problem, pay off the CHECK and not bad save!!!

We have tested this scanner ourselves on different machines and he showed excellent results We now recommend it to EVERYONE! So that you don't get caught Chinese fake, we publish here a link to the official website of Autoscanner.

Get behind the wheel and buckle up. Always use seat belts, do not neglect this safety measure!

Insert the key into the ignition lock. The ignition key hole is often located next to the steering wheel. The keyhole looks like a round metal plate with a slot for a key; it is often illuminated. Having found the well, insert the key into it to the end.

The car key is provided by the manufacturer, but you can make a duplicate of the original key. A duplicate will only work if it is well made.
Some modern models cars do not have a traditional metal key. They are equipped with a system electronic ignition. In this case, you need to look for a button that says "engine start", which should be in a prominent place near the steering wheel.

If your car is equipped with an automatic transmission, before turning the key, you must move the gear lever to the “P” or “N” position. The automatic transmission is designed to save the driver from having to change gears himself.

On vehicles with automatic transmission, there are only two pedals. The "third pedal" is simply a platform for resting the left foot.
Many automatic boxes gears are equipped with protection that prevents the engine from starting if the gear lever is not in the “P” or “N” position (“Park” or “Neutral”). This prevents the engine from starting when the vehicle is in gear.

If your vehicle is equipped mechanical box gear, move the shift lever to neutral.

On vehicles with a manual transmission, there are three pedals. The far left is the clutch.
Before turning the ignition key, it is important to make sure that the car is in neutral, that is, no gear is engaged. If the gear is engaged, then when you try to start the engine, the starter will transfer force to the wheels, and you will feel a sharp jolt. This could damage the transmission and starter.
You can make sure that the gearshift lever is in the neutral position by rocking it from side to side. If the lever moves easily, then none of the gears is engaged. If the lever does not move and sits firmly in place, then the gear is engaged. In this case, you need to depress the clutch and disengage the gear.

To start the engine, turn the key in the ignition switch. Turning the key, you will feel two intermediate positions, and the third position, which is spring-loaded, starts the engine. Turn the key with the same hand as you inserted the key, and be sure not to pull it out while turning it.

As soon as you turn the key to its extreme position, release it and the spring will return it to the second position. If you keep the key in extreme position, you will hear unpleasant sound corresponding to the fact that the starter will prevent the engine from working. This is very bad for the starter.
The first two positions are called "ACC", which is an abbreviation for "accessories" (accessories), the second position is called "ON" or ignition. In the first position, power is supplied to the radio and other car accessories; the ignition position is the position to which the key returns after starting the engine.

Even a fully serviceable car does not always start the first time. Don't worry if the first launch attempt is not successful - try a few more times.

The steering wheel has a lock that prevents the steering wheel from turning; the lock is released when you turn the key in the ignition switch to the second position. The steering wheel lock is a device that prevents the car from being stolen. Sometimes the steering wheel lock makes it difficult to turn the key in the hole, in this case it is necessary to turn the steering wheel slightly left and right while applying a little force to the key.
If the car does not start, try depressing the brake or clutch. Some newer vehicles have a device that prevents the engine from starting in gear.
If the engine still does not start, try turning the key in a different direction. Some old cars are very different from modern ones.

Pay attention to the position of the gear lever. On some modern boxes gear electricity is not supplied to the starter if the clutch pedal is not fully depressed.

When the engine is already running, Not drop the clutch pedal if the drive gear is engaged; this will stop the engine and jerk the entire car. You can prevent this by first making sure the vehicle is out of gear by wiggling the shift lever as described earlier.

Check your mirrors before driving and always drive safely.

Part 2

If the engine does not start

The engine may not start for a variety of reasons. Read the owner's manual and take the car to a mechanic if you suspect a problem. If there is no mechanic nearby, but you need to drive, try to fix the cause of the problem yourself.

If you hear clicking sounds when you turn the key, but the engine does not start, the problem may be in the alternator. Take the car to a mechanic to find out what the problem is and if it needs to be replaced.

After starting the engine, but before driving, make sure that there are no animals under your car - they are very fond of hiding or basking under the car.
Make sure you are using the correct key for this vehicle. Some cars have a protection system that blocks the engine from starting when you try to start the car with a different key. If your car key has a built-in “chip” located near the base of the key, then the car will not start even with a copy of the key. The key will release the steering wheel, but the engine will not start.
To prevent rolling away on vehicles with manual transmission before depressing the clutch, apply the handbrake.
On push-button start vehicles, after all pre-start procedures, you will need to press the "Start" button.
On vehicles with diesel engine such as GM or Ford, you need to warm up the spark plugs, Dodge cars warm up the air heater intake manifold. Ready to start is displayed on dashboard, a few seconds after the ignition is switched on. Read the instruction manual for more information.
Examine the car before driving it. Management skills and familiarity with technical device make it very easy to operate.
Some cars like brand Renault, are equipped with an immobilizer built into the key - you need to press the button to open / close the car before starting the engine.

Warnings

When driving a vehicle with a manual transmission, be careful with the clutch to avoid unwanted vehicle jerks. If you release the clutch on a car with running engine in gear, the car will jerk forward or backward, depending on which gear is engaged. This jerk can cause an accident or injury if an obstacle or a living being appears in the path of the vehicle. Before driving on public roads, learn how to operate a manual transmission on the driving range.
The car is a tool heightened danger not a toy. People who do not know how to drive a car, or who are unable to do so for any reason, may be involved in an accident and incur or cause serious injury or death to others. If you do not know how to drive or otherwise cannot drive a car, never drive or start the engine. If you are going to make the first trip, be sure to make it under the supervision of an experienced instructor!
If the car does not start, do not turn the engine with the starter. You can try to start the engine with a starter for 60 seconds every 5 minutes. The starter should then be allowed to cool. If you do not maintain this pause, you can burn the starter. The starter is a small electric motor that turns the car's engine. If this happens, then the only way to fix the problem is to replace the starter. If the engine does not start after 60 seconds of rotation, it is very likely that it is defective and needs to be serviced.

About driving own car dream of many compatriots since childhood. Sitting behind the wheel, you can break with the breeze at full speed under the roar of the engine. However, certain difficulties lie in wait for some motorists at the start, especially if they studied in a car with “mechanics” and bought a car with automatic transmission. In this case, the question of how to start an automatic machine will turn out to be relevant. ask more experienced car owners it is not always possible, so you have to learn the basics on your own.

Unlike cars with a manual transmission, automatic transmission has many more advantages while driving. With it, many of the standard maneuvers that the driver must perform on the road are facilitated.

At the same time, there are several types of gearboxes that do not have a clutch pedal in the cabin:

classic machine;
robotic box;
variable speed drive.

The principle of controlling them is similar, and in terms of functioning, “robots” can be distinguished a little, having a difference in the number of gears, as well as a slightly different lever stroke. But for a person sitting behind the wheel, these differences at first will hardly be noticeable.

Having adjusted the seat and steering wheel in height and inclination, we check the position of the gear lever in order to figure out how to start the car on the machine. It must be in a neutral point or in a "parking lot". When other modes are set (drive "D", reverse "R", imitation of mechanics "M"), a lock is started in the car. The machine will not respond to such a start.

Note: the first rule is to set the lever to the "N" or "P" position. In any other position, “fool protection” will work, that is, the electronics will not allow the engine to be started in a gear intended for movement.

Even this axiom can unbalance a young driver. Which of the modes would be preferable in such a situation? Fundamental difference there is no automatic in how to start the car from neutral or parking. It's a matter of taste or habit.

During a car stop, drivers often put the car on “P”, which is why many start off from this position. The neutral mode in the machine performs the same role as in mechanics. If you start the car from it, it is recommended to first install the car on the handbrake, and then start the engine.

For a winter start, it is recommended to use parking, which in this case has more advantages. In the car on "P" the brakes are not used, but the shaft is blocked. Decreases the chance that brake pads freeze to discs or drums.

At the next stage, we depress the brake pedal, especially for the “N” mode, this is not necessary in parking. With the pedal depressed, it will be easier to switch to the "drive" position. Most often, this rule is developed to automatism.

Now you can insert the key into the ignition and turn it clockwise. During this standard procedure, the motor accelerates to approximately 1000 rpm.

Push a car with automatic transmission

The machine is not always in working order. Out of habit, after the "mechanics", some drivers try to start the car on the machine from the pusher. However, such an occupation in most cases leads to sad consequences.

There is no rigid connection, unlike the manual transmission, in the automatic transmission between the crankshaft and the wheels. Clutch elements move due to pressure drops in the torque converter. This means that, according to theory, it will not be possible to forcefully rotate the engine with automatic transmission on the descent with “D” turned on. Although this rule can be refuted by individual daredevils on some car models.

Honda owners, having accelerated it over 30 km / h and switched the lever to drive, managed to start the engine.

On other machines, the empirical acceleration rate was achieved at 50 ... 60 km / h. However, it is worth noting that the cars were equipped with a classic transmission with torque converters.

Start on automatic transmission in cold weather

Many automatic transmissions, unprepared for winter conditions operation, can bring unpleasant surprises to their owners. They lead to difficult starting of the engine. excessive thick oil, which increased its viscosity at low temperatures at night, unable to perform its functions effectively. It leads to the need to increase the effort to rotate the shafts of the "machine".

This means that the motorist must take care of the replacement in a timely manner. transmission oil. The cleaner it is, the easier it is for the car to start. For problem car it is recommended to “light up” from the corresponding equipment or an already working car.

None of the car owners are immune from sudden problems. One of these problems can be a dead battery. It takes a long time to charge it. It's good if the battery is dead in the garage when starting the engine, but what to do when you are away from home?

It is this problem that will be discussed in the article. You will learn how to start the car if the battery is suddenly dead. Simple Tips will help you to return home or get to the service station.

But before you solve the problem with a dead battery, make sure that it is because of it that you cannot start.

Signs by which a weak battery level is determined:

peppy engine noise changes to a slow and viscous sound;
the dashboard glows dimly;
the charge indicator is on;
under the hood you can hear the charging relay clicking.

4 ways to start the car if the battery is dead

Donor car. This method works on cars with any transmission.

You will need:

donor car with a good battery;
starting wires with crocodiles.

Procedure
Park cars nearby and turn off everything electronic devices: headlights, radio, stove. Connect the batteries with wires in parallel - plus to plus (red), and minus to minus (black). Start the donor for 2-3 minutes, and then the car with a dead battery. Then disconnect the wires and give the engine time to run at increased speed so that charging goes faster.

Tow. This method will help if the car is equipped with a manual transmission.

You will need:

a cable four meters long;
second car.

Procedure
Connect both machines with a cable. When you start to accelerate, depress the clutch and shift into second gear. Look at the speedometer scale, when reaching a speed of 15 km / h, slowly release the clutch pedal. You will feel a slight jolt and the car will start.

Depress the clutch again, give it gas. Check that the engine is revving steadily, shift the gearshift lever to neutral and release the clutch pedal.

The car can be started with a manual pusher. This requires several people who will push the car. The sequence of actions is similar.

Crooked starter. Motorists nicknamed the crooked starter special device, which was inserted into the pulley hole crankshaft and then twisted it several times. This method was popular and was used on old Soviet cars. Modern cars not equipped with useful device. But human ingenuity does not stand still and always helps to get out of a hopeless situation.

You will need:

rope for five meters;
gloves;
jack.

Procedure
Put the car on the handbrake, if it has front-wheel drive. To slow down the car rear wheel drive, lay bricks, stones or wheel chocks under the wheels. Using a jack, raise the drive wheel and wrap a few turns of rope around it. After that, turn on the ignition and first gear. The end of the rope must be pulled sharply, applying all the force to spin the wheel.

Launch device. Starter charger is a quick way to start the engine.

There are two types:

working from a network 220V;
autonomous with a large capacity.

Procedure
Connect the ROM wires to the battery. Wait five minutes for the battery to recharge. Start the car and disconnect the wires of the device.

Battery maintenance rules

To prevent the battery from being discharged, check it regularly. By following simple rules, you will increase the battery life and you will always be able to start the car engine.

Maintenance free batteries
Owners of these types of batteries do not need to carry out frequent checks. All you need to do is periodically wipe and monitor the integrity of the case.

Serviced batteries
Owners of these types of batteries should follow a number of simple preventive steps:

clean from dirt;
check the electrolyte level;
