Has the battery accumulated, how to start a car? How to start the car yourself, if the battery has sat down

The situation when the battery goes out of order is familiar to any car owner. As a rule, this happens at the most inopportune moment and threatens with very serious trouble. If in urban conditions the discharge of the battery threatens to be late for work, then on the intercity road such a breakdown often threatens the life of the driver and passengers. Especially if this excess occurred in the winter season. This article will be devoted to how to get a dead battery yourself.

The main problems caused by seated batteries

The main purpose of the car battery is to provide power supply to the main consumers of the internal power supply of the machine when the engine is off. It is thanks to it that the driver can use external lighting devices without starting the power unit, provide an optimal microclimate in the lounge or enjoy the multimedia system in an autonomous mode.

But the most important function of the battery of any vehicle is to ensure the operation of the ignition system. The main insidiousness of this indispensable car aggregate is that if the battery has sat down, how to start a car becomes very difficult, and sometimes even an unsolvable problem.

Principle of operation

In short, the battery is an autonomous source of electrical energy. The renewability of current production is due to the electrochemical reaction caused by the interaction of lead and its oxides. The catalyst of the process is an aqueous solution of sulfuric acid. With the passage of time, the concentration of sulfuric acid decreases and the efficiency of the battery decreases markedly. The generated current and voltage parameters become insufficient for efficient operation of electricity consumers.

That's why, if the battery has sat down, how to start a car becomes a very pressing issue. With a cranked battery, starting the engine is difficult or impossible. Like the work of all other electrical appliances of the car, from the radio to the headlights.

A typical device

Today the most common constructive scheme of the car battery device is the following:

• Positive and negative electrodes are immersed in a special body, made, as a rule, of plastic;
• The body contains several chambers separated by special conductive separators and bridges preventing the closure of the electrodes;
• The chamber is filled with a special electrolyte, which is a mixture of sulfuric acid and distilled water.

This design allows you to use several methods of "resuscitation" of the unit, when the battery has sat down. How to start a car with a discharged device? It is simply impossible to do this. It is necessary to urgently search for a place of "make-up".

How can I tell if the battery is dead and how do I start the car?

To determine that the vehicle's battery is discharged is quite simple:

• When the ignition of the engine is switched on, the starter generates lingering and strained sounds;
• The indicators placed on the dashboard are either dimmed or are not switched on at all;
• Do not work or function with intermittent electrical car appliances.

All these symptoms most often indicate that the part is empty or even completely planted.

How to get a dead battery? Reasons for a dead battery

The reasons for which it can be discharged and stop correctly performing its basic functions may be several. The main ones are the following:

• Violation of the integrity of the body of the unit. Cracks or holes in the battery cover lead to electrolyte leakage, which causes the device to fail.
• Change in the properties of the electrolyte. During operation, the concentration of sulfuric acid in the composition of the catalyst liquid is subject to leaching due to natural loss.
• Non-observance of the rules of operation. For example, left for the whole night included the driving light will inevitably put the car owner in front of the question: how to start a car, if the battery has sat down? What to do and how to open a car?
• Weather and climate conditions. As a rule, the work of a not fully charged car battery is greatly hampered by low ambient temperatures and excessively high humidity levels.

Nevertheless, there are several ways to solve the problem of how to start the car yourself if the battery has sat down. We call the most effective.

Special charger

This is one of the most simple and effective methods for solving the problem of how to start a car, if the battery has sat down. Discharging the battery is a temporary and reversible process. When the unit is fully discharged, you can use a special third-party start-up charger. It is relatively inexpensive, but in emergency cases it can provide invaluable assistance when starting the engine. The algorithm for using ROM is quite simple:

• The device is connected to the electrical network;
• Wire marked "+" - to the corresponding battery terminal, and the negative cable to the motor housing, preferably closer to the starter;
• The mode switch is moved to the "Start" position;
• The car ignition system is activated.

Today, in the market of automobile spare parts, accessories and equipment, ROMs with high mobile properties, equipped with their own batteries or having the ability to connect to the electric circuit of another car can be found.

"Smoking"

The most famous, traditional and common way, when the battery in the car has sat down, how to start it. To implement it, however, it will take another car, the battery of which is in perfect order.

When using this method, it must be taken into account that the voltage of the batteries of both machines must be the same. In addition, you need a set of wires with a cross section of more than 16 millimeters and equipped with special clips - crocodiles. The order of actions will look like this:

• Both cars are installed in such a way that their engine compartments are next to each other, but do not touch each other;
• The engine at the donor machine is turned off, and the negative terminal is disassembled from the battery of the receiving machine;
• The plus terminals are interconnected. Then the minus of the donor machine is connected and only after that - the minus of the defective car;
• The engine of the serviceable car starts and runs for about five minutes, after which an attempt is made to start the engine of the "victim".
• After achieving a successful result, you should not rush to turn off the improvised electrical network, in order to enable the seated battery to be recharged.

This way of launching can often be seen on the streets of any city, especially in the winter.

High current application

Today, on the market of specialized automotive equipment, you can find autonomous installations that produce high voltage and high current. Use these devices must be very carefully for the following reasons:

• The use of high current units can disable the computer equipment of the car;
• The use of such systems significantly shortens the life of any battery.

In addition, since these devices are quite expensive, and are not required so often, their acquisition for personal use is inexpedient from the economic point of view. It is better to use the equipment of the nearest car-care center. But how to get there?

Forced acceleration, towing, launch from the pusher

Another way to solve the problem, what to do, if the battery has sat down, how to open and start the car, there can be a proven way to start the engine from the pusher. To use it, you will also need a second vehicle. It is desirable to be more powerful than a defective car. The principle used is quite simple:

• Using a towing line 4-6 meters in length, the defective vehicle is attached to the tow;
• The leading car is gaining speed of about 10-15 km / h;
• The driver of the towed vehicle includes the second or third gear and smoothly releases the clutch.

This way of bringing the engine into a working state is not directly related to the operation of the battery. But it allows you to start the engine quite efficiently. And with the engine running, the generator will start charging and the battery that has accumulated.

Using a mechanical drive

Old grandfather's method, despite all its inconvenience, is often the only way to start a car engine. One of the advantages of this method is the absence of the need to attract outside help. The essence of the method is quite simple: a special metal handle, which is called a "curve starter", is inserted into the corresponding hole, and by applying muscular force turns the knee shaft of the engine.

Thus, a car battery that has landed is not a verdict at all. Even with the discharge of the battery, the car can easily be brought into service by its own forces. But it is best to constantly monitor the battery condition, the level of electrolyte and the performance of devices.

So, we found out what to do, if the battery has sat down, how to start the car in different ways.
