After the positive and negative poles of the battery are reversed, the electronic components of the vehicle will be damaged, and the most common problem is to burn out the safety and some control units.

Because many control units have diodes, the characteristics of the diodes are unidirectional, so once the reverse voltage is added, it may cause the breakdown of the diode and cause a short circuit in the positive and negative poles of the battery.

1. Reverse connection will short circuit: the first task is that the motor will reverse and will not sound, and some items with electronic components on the car will be burned, such as generator CD, if it is a car, the items will be burned.

2. Burn the insurance: You can also burn the insurance, which is a possibility, and another possibility is that if the car is connected to the battery in the positive or negative reverse and tries to start, it will burn the starter.

3. Damage to the computer board: The computer board of the car with the computer board adjustment system is always in a power-on state, once the power supply is reversed, the first task is to burn this kind of circuit, which may cause a lot of electrical damage, which can not be predicted. In general, computer boards and sensors are most likely to be damaged.

Signs of the battery before it is damaged:

1. It is more difficult to start the vehicle than usual, and it needs to be ignited more than once, and it feels that the starting power is insufficient.

2. When the vehicle is idling, the headlights quickly turn from bright to dark, indicating that the battery is insufficient and needs to be replaced.

3. When the battery life is approaching, it will affect the work of the generator. The generator usually makes an unusual noise when the vehicle starts, usually a slight squeak, but it may disappear in three or two seconds or less. As the power becomes lower and lower, the frequency and duration of this sound will gradually increase.

It will burn out the positive and negative poles of the battery, and the ignition will fail anyway.

1. The computer board of the car with the control system of the computer board always keeps the power on, once the power supply is reversed, the first thing to burn is this kind of circuit, and it will also involve the sensor.

2. There are two possibilities for burning the circuit, namely, burning off and burning short, burning, then, "this is the end", burning short, will continue to burn other electrical appliances until it is burned outFuses

3. Steps to check the degree of damage caused by the reverse connection of the battery: start from the fuse, and then, detect the battery voltage, install the battery correctly, turn on the power, observe the instrument display, switch the electrical appliances, start the car to observe the display, turn on the air conditioner, etc., in this process, if there is a fault, it needs to be repaired, usually the computer board and sensor are most likely to be damaged. If you don't have the knowledge, contact a professional car maintenance professional to ensure your safety.

1. If it is reversed, it will be short-circuited, first of all, the motor will be reversed and it will not sound, and some things with electronic components on the car will be burned, such as generators, CDs, and if it is a car, there will be more things that will be burned.

2. It will also burn the insurance, which is a possibility, and another possibility is that if your car is connected to the battery in the opposite direction and tries to start, it will burn the starter.

3. The computer board control system of the car, the computer board is always in a state of power, once the power supply is reversed, the first thing to burn is this kind of circuit, which may cause damage to many electrical appliances and cannot be predicted. Usually the computer board and sensors are most likely to be damaged. [Summary].

What are the consequences of the positive and negative electrodes being reversed when the car battery is installed? [Question].

1. If it is reversed, it will be short-circuited, first of all, the motor will be reversed and it will not sound, and some things with electronic components on the car will be burned, such as generators, CDs, and if it is a car, there will be more things that will be burned.

2. It will also burn the insurance, which is a possibility, and another possibility is that if your car is connected to the battery in the opposite direction and tries to start, it will burn the starter.

3. The computer board control system of the car, the computer board is always in a state of power, once the power supply is reversed, the first thing to burn is this kind of circuit, which may cause damage to many electrical appliances and cannot be predicted. Usually the computer board and sensors are most likely to be damaged.

The reverse battery connection may be fatal to the car, and now the car has a driving computer, which is responsible for the collection, processing and control of various parameters of the engine. The trip computer is a semiconductor electronic device, which is very sensitive to the reverse connection of the power supply and can easily burn out. Therefore, the degree of harm of reversing depends on the complexity of the electronic devices such as the driving computer in your car.

Hello The positive and negative poles of the battery are reversed, and it is possible to burn the on-board electrical appliances, and I am really helping you look forward to it.

If the battery is installed, it will burn the vehicle's insurance, and it will seriously burn the driving computer and other electrical equipment.

The positive and negative poles are reversed, which will burn the fuse and the computer.

If you are lucky, you will burn insurance, and if you are unlucky, you will burn electrical appliances, modules, and computers.

[Summary].Glad you asked. There are generally two reasons for the problem to help you find out:

First, the plates of the single-cell battery in the assembly are reversed; Second, in the use of the battery, due to the reduction or even complete loss of the capacity of a single battery, the single grid will not only not be discharged, but will be reversed, resulting in the original negative electrode becoming positive electrode and positive electrode becoming negative electrode.

Hello, glad for your question. We're here to help you sort out the answers to your questions. Please wait....Glad you asked.

Here to help you find out that there are generally two reasons for this problem: first, the plate assembly of the single-cell battery in the assembly is reversed; In the use of the battery, due to the reduction or even complete loss of the capacity of a single battery, the single cell brigade base will not only not be discharged, but will be recharged, resulting in the original negative electrode becoming positive electrode and positive electrode becoming negative electrode. The damage of the positive and negative poles of the battery against the battery is very great, and it should be corrected in time.

A car battery is a kind of storage battery, which can convert chemical energy into electrical energy and provide power for automobile lighting and audio. Batteries have positive and negative electrodes, and car batteries are the same. What if you accidentally pick it up? Let's take a look.

Does it have any effect if the positive and negative poles of the car battery are reversed?

The positive and negative poles on the battery are reversed, because it is not in the state of the car, so the generator is not working, and will not charge the battery, so it will not cause any harm to the battery, but it may damage the car and even burn the parts.

The control system produced by the general manufacturer, such as ECU, has been strictly tested by EMC and other standards, and it has the requirements of anti-reverse, and the possibility of misoperation of this reverse connection has been considered in the design, so even if you connect the positive and negative lines on the opposite side of the battery, it will not directly cause them to be damaged, but they will not work normally.

Some of the aftermarket to increase their own vehicle appliances, such as some navigation systems, some **** devices and the like, the scale of the larger brand manufacturers, generally will also take into account the anti-reverse design protection, but some small manufacturers, in order to save costs, or design negligence, it is difficult to say, if there is no anti-reverse design, there will generally be electrolytic capacitors, electrolytic capacitors will explode directly.

Generally, plug in the opposite, the current may increase instantly, the safety device on the car will play a protective role, often most of the cases are burned insurance, you put the battery positive and negative line, upside down, replace a insurance, basically there will be no problem, but if there is smoke or odor, of course, it is burned something, you must carefully find and solve the problem before you can power on.

Some cars rely on the battery to save part of the data, if the battery is powered off, you may have to find the manufacturer's after-sales part to rewrite the data. If you start it directly, it is not ruled out that the boot system may be burned.

How to repair the positive and negative poles of the battery

If the positive and negative poles of the car battery are wrong, the engine will not be started, the computer control circuit will not work, and even various other parts will be burned out. Do it absolutely correctly.

Operation: Turn off all electrical equipment before changing the battery. After replacing the battery, gradually turn on the electrical equipment of each branch step by step. Before the shunt switch is turned on, the starting motor rotation direction can be turned on first. This reduces damage to the equipment.

The normal positive and negative electrodes cannot wait for the battery to be damaged, and the wire or appliance that constitutes the short circuit has been burned out, or the battery pile head has been burned and melted. At this time, clean the battery in time after discovery, and find the cause of the short circuit after clearing, the battery will generally not be damaged. However, if the battery is short-circuited with a high-current short circuit, the inside of the battery will soon be damaged after a violent chemical reaction.

As we all know, the car battery is installed in the positive and negative poles, must be installed in the correct way, once the wrong connection will cause a lot of trouble, so what will happen if the car battery is connected to the wrong positive and negative poles?

1. If the car has a computer control system, this computer board is always in a state of power. When the positive and negative poles of the battery are reversed, this type of circuit will be burned out, and the sensor will also be damaged.

2. If the positive and negative poles of the battery are reversed, it will be short-circuited, first of all, the motor will be reversed, and it will not sound at the same time. Some items with electronic components on the car will be burned, such as generators.

3. There is also the possibility of burning the insurance, if the positive and negative poles of the car battery are reversed, try to start at this time, it is likely to burn out the starter.

The car battery is generally used for about three years, and if the maintenance method is not correct, it is likely to need to be replaced in two years. If the owner parks the vehicle for a long time, it is recommended to power off the battery and directly remove the negative wire of the power supply, so as to avoid static leakage caused by the battery due to long-term non-use.

The consequence of the positive and negative poles of the battery being reversed is that the circuit is burned.

There is a computer board control system of the car, its computer board always remains energized, once the power supply is reversed, the first to burn is this kind of circuit, burned circuit is a momentary thing, when you see smoke and other phenomena, may have caused a lot of electrical damage, can not be predicted.

Distinguish between positive and negative poles of automobile batteries

The positive and negative poles of a car battery are well distinguished. In general, the positive pole has a + and the negative pole has a -. And the positive terminal post is thicker than the negative terminal post, and the positive terminal has more wires, and the negative terminal post has only one wire.

Car batteries

A car battery, also known as a battery, is a type of battery, and its working principle is to convert chemical energy into electrical energy. Usually, people refer to batteries as lead-acid batteries. That is, a battery mainly made of lead and its oxides, and the electrolyte is a sulfuric acid solution.

The battery uses a lead plate filled with spongy lead as the negative electrode, a lead plate filled with lead dioxide as the positive electrode, and 22 28% dilute sulfuric acid as the electrolyte. When charging, electrical energy is converted into chemical energy, and when discharging, chemical energy is converted into electrical energy.

When the battery is discharged, the metal lead is the negative electrode, which undergoes an oxidation reaction and is oxidized to lead sulfate; Lead dioxide is the positive electrode, which undergoes a reduction reaction and is reduced to lead sulfate. When the battery is charged with direct current, lead and lead dioxide are generated at the two poles, respectively. After the power supply is removed, it returns to its pre-discharge state and forms a chemical cell.

Lead-acid batteries are batteries that can be charged and discharged repeatedly, and are called secondary batteries. Its voltage is 2V, and it is usually used in series with three lead-acid batteries in series, and the voltage is 6V. The car uses 6 lead-acid batteries connected in series to form a 12V battery pack.

Ordinary lead-acid batteries should be supplemented with sulfuric acid after a period of use, so that the electrolyte remains containing 22-28% dilute sulfuric acid.
