I would like to ask the experts a question about the battery power loss, do you use 4S to check the

Synthesize your description.

1. There is the possibility of navigation discharge, but how to detect is the key, any navigation machine, there must be more than two power supplies, one for the battery to be energized, and one for the ACC key to control the electricity. If ACC is connected to constant electricity, it will cause discharge, and it will generally run out of power overnight.

2. Short-distance running may also cause insufficient charging and power loss, however, the probability of this problem is a little smaller, the current car generator system is still very powerful, after the loss of power, as long as the car is 5 minutes, absolutely no problem can be started again, do not believe it.

3. The weather is cold, if the engine oil is suitable, there is no problem for the gasoline engine.

4. The normal power generation is in the middle of 14V, if it can reach this value, it can mean that the generator system is normal.

Let's talk about how to detect discharge:

1. Remove the negative pole wire of the battery, string the multimeter into the middle, one meter pen is connected to the negative pole of the battery, and the other meter pen is connected to the negative pole wire. Adjust to DC current gear 20A, close the key and various electrical equipment and doors, at this time the discharge current should be, if it is greater, it means abnormal discharge.

2. Same as above, but the middle is a small bulb of 2W and 12V, close all electrical appliances and doors, and the bulb should be turned off at this time, and there should be no faint red wire.

3. The easiest way, the car runs back, stops, removes the negative pole of the battery, and then installs the negative pole when starting the next morning, if it can start, the car is discharged, if it still can't start, it is the battery self-discharge.

Hope it helps, thank you.

The navigator does not consume much electricity, under normal circumstances, as long as your car moves together, the generator will charge the battery according to the battery voltage, if the battery is always losing power, there may be several situations: 1. There is a problem with the generator; 2. There is a problem with the charging device; 3. The line (positive pole) is grounded; 4. There is a problem with the battery. If the above situations are not easy for you to check and solve by yourself, it is best to go to the 4S store for a comprehensive inspection in order to make a claim.

You'd better check it at the 4S shop, or it may be self-discharge, just check it. There may be issues elsewhere.

It's better to go for an overhaul.

It's better to look it up.

Hello dear, the battery power loss will report the fault indiscriminately**. First, if the battery of the vehicle is said to be severely damaged, the vehicle-related system will have a garbled pattern, and the vehicle will report a series of faults with too low voltage. Second, the loss of the vehicle battery will cause the vehicle to fail to start the system normally, which means that the battery needs to be charged or replaced with a new electric Weiliang section bottle.

Third, under normal circumstances, the service life of the battery is about 3 to 5 years, if it exceeds this service life, it is recommended to replace it in time. Hello, I hope I can help you, I wish you a happy life, good luck, eternal youth, if you have any questions, you can consult at any time, I will reply to you as soon as possible.

When the car battery failure indicator light on the car dashboard lights up, it is necessary to pay attention to it. As long as the fault light is on, it means that the car battery has failed, or the car battery is found to be bulging, generally speaking, there are two reasons for the battery bulging, the first is a long-term charging ,..The second is aging.

It's just that the car doesn't catch fire.

There are several reasons why a car battery loses power:

1. As long as the battery is connected to the car, many electrical appliances have been using electricity, but the current is very small, and the power consumption is very small and can last for many, many days, so if the vehicle does not drive for a long time, it is recommended to remove the negative pole pile head of the battery.

2. Even if the battery is not connected to the electrical appliance, it will have a certain amount of power loss. If the car does not move for a long time, it cannot be charged, and the power consumption is very large when it starts, so it is easy to lose power, and if you lose a battery, the battery performance will drop a lot. The battery shrinks as the amount of power is used.

3. The power release of the battery has a cliff effect, that is, the discharge curve of the new battery is relatively linear, and the battery with a long decline in performance, looking at the indicators, the power seems to be full, but when it reaches a certain level, it will suddenly run out of power.

4. Finally, the temperature factor, that is, the weather, is also an important factor. Because low temperatures can greatly reduce the performance of the battery. For example, the battery performance is very poor, and it is fine in summer, but in winter, as the temperature decreases, the battery performance further decreases, and there will be a situation where the power loss cannot catch fire.

Battery maintenance. The battery is most afraid of low temperatures, and in a low temperature environment, the battery capacitance is much lower than that at room temperature. Therefore, we should check and maintain it in time, and pay attention to it in daily life:

1. Avoid parking the car in the open-air parking lot for a long time, if it is parked for a long time, the battery must be removed and taken away to prevent the battery from being damaged by icing.

2. The car engine is not easy to start in winter, and the time to start the car each time should not exceed 5 seconds, and the interval between starting again should not be less than 15 seconds. In the case that the ignition is still not ignited after multiple starts, the cause should be found from other aspects such as the circuit, ignition coil or oil circuit. Avoid multiple uninterrupted starts, which can cause the battery to burn out due to over-discharge.

3. The car battery should be charged frequently, and the battery will slowly discharge itself until it is scrapped after not being used for a long time, so the car should be started every once in a while to charge the battery.

4. Clean the binding post of the battery every once in a while, and apply special grease to protect the wiring harness. Always check the accessories and connections on the battery.

5. It is forbidden to use automotive electrical appliances after the car is turned off, and the engine will cause damage to the engine if it does not generate electricity.

The loss of power in the car battery will cause many failures, and the most troublesome fault is that the car cannot ignite.

First of all, some models will have a battery warning light on the instrument.

Most of the batteries also have detection holes, if the detection holes are green, then it means that the battery is good is no problem, if the detection holes are black, then it means that the battery is seriously depleted and needs to be charged. If the detection hole is white, then the battery is damaged.

If it is difficult to start, it takes a long time or many times to start each time, or the cold car cannot be turned on, which is a sign of battery loss.

When the vehicle fails to start, sometimes you can hear the "click" of the starter magnetic pack, or when there is no response, then it is likely that the battery is running out of power.

In severe cases, the headlight light becomes dim or the horn sound becomes quieter.

When the ignition switch is turned on, there will be a delay phenomenon in the vehicle's electrical equipment meters, display screens, etc.

After the above phenomenon, you can go to the maintenance plant through the voltmeter and battery detector for inspection, if the voltmeter measured battery voltage is lower than 6V, you need to replace the battery, if it is 8-10V, charge it first and then test. If there is a battery tester, the measurement results are more accurate, and the tester will directly give the result of charging or replacement. Because sometimes the voltage of the measuring battery is 12V, but the voltage will drop sharply when it starts, that is, the battery cannot store power, so the detector will also give the result of replacement.

There may be situations where the horn is not loud enough, the headlights are not lit, the dashboard is not lit, the car cannot start, etc. Hope the above is helpful to you, thanks.

If the car battery loses power, the car will not catch fire, and the car will not be able to start and drive.

1. If the battery status indicator lights up, it means that the battery level is too low. It is necessary to check the status of the battery, there is an observation hole above the battery, check the color displayed inside through the observation hole, green represents the battery in good condition, black represents that the capacity of the battery is insufficient, and white means that the battery is about to die, and then it needs to be replaced in time.

By checking the color of the observation hole, you can determine whether a new battery is needed.

2. You can hear the "click" when ignition, which means that the battery is seriously damaged and needs to be replaced in time.

3. At night, according to whether the night light is darker than before, or, through the comparison between the driving light and the idle light, if the idle light is obviously much darker than the light in the driving, in order to avoid driving safety, the new battery should be replaced in time. It should be that at idle, the lights are basically powered by batteries.

The car battery needs to be replaced in the following cases:

1. The brightness of the lights on both sides becomes dim when idling.

When the car is idling, it relies on the remaining power of the battery to provide electrical energy, and we can keep the vehicle in an idle state before turning off the engine and stopping, and observe the brightness of the lights at this time.

If the brightness of the lights on both sides is not the same, it may just be because of the problem with the lights, but if the brightness of the lights on both sides is not enough, it must be a problem with the car's battery and needs to be replaced in time.

2. The start of the car is obviously abnormal.

The car is the same as the computer, there is a specific time limit when starting, under normal circumstances, the starting time of the car will not exceed five seconds, once it exceeds this time or obviously feels that the car starts weakly, it means that the battery can no longer provide enough power for the start of the car, which means that the battery has to be replaced.

In addition, some unaware car owners will play two or three times, this frequency is not limited, but the interval between two starts shall not be less than 15 seconds, too frequent ignition will burn the battery.

3. The battery fault light is on.

Generally speaking, most cars have a battery warning light, if this light is on, it is a reminder to the owner that the battery should be replaced.

This situation mostly appears in the battery used for about 4 years, from the 4th year, the battery storage capacity and service life will slowly decline, the car in the start, inevitably there are small problems, the older the car, the more you should pay attention not to park the car in the open air.

Dear, this question is up to me, it takes a little time to type, please be patient, thank you!

This is to say that the judgment of the battery. Need to make a measurement, if you say this starting voltage. That is to say, the moment the engine starts, this voltage is lower than 9 volts, then the battery needs to be replaced.

There is also the need to use a battery tester to test the service life of the battery, repair shops or 4S shops have, if the service life of the battery is less than 50%, the battery also needs to be replaced. There is also this observation hole on the current battery, if the observation hole becomes black or red, the battery also needs to be replaced, if it is green, it is normal.

Quickly determine whether the battery is damaged or undercharged, accurately calculate the charging time, and prevent overcharging and loss of life?

<> "In the process of using the vehicle, failure is a common thing, as the owner, to find the cause of the failure in time to ensure the safe driving of the vehicle. So will the finch burn the battery and lose power, and will it stare at the fault code?

When this happens, we need to go to the repair shop or 4S shop as soon as possible for maintenance and eliminate the fault code.

Batteries are an indispensable part of automobiles and can be divided into traditional lead-acid batteries and maintenance-free batteries. Because the battery is made of lead-calcium alloy as a grid, the amount of water decomposition produced during charging is small, and the amount of water evaporation is also low, and the shell adopts a virtual sealing structure, and the sulfuric acid gas released is also very small, so compared with the traditional battery, it has the advantages of not adding any liquid, docking pile head, and long power storage time.

The reason why the engine fault light is on after the loss of power may be that the fault formed after the battery is lost**, you can go to the 4S shop to eliminate it first, if the fault code still jumps out later, it needs to be repaired.

The engine fault light is the most common light in actual use, and if the engine failure is blind, the light can be turned on in most cases. However, when the oil pressure lamp, water temperature warning lamp, handbrake lamp, and tire pressure lamp are on, it is necessary to stop and check immediately, and only if there is no abnormality can it continue to open.

When the engine fault light is on, it means that the engine parameters have changed, and excessive carbon deposition is a common cause of the chaos of engine parameter changes. If this problem is not solved, the combustion state of the engine will not be adjusted to the normal state, and the engine fault light will of course be always on and will not disappear automatically.

Battery introduction:

A battery is a battery that can be recharged after discharging. There are lead-acid batteries, nickel-iron batteries and nickel-cadmium batteries. The positive electrode of the lead-acid battery is lead dioxide, the negative electrode is lead, and the electrolyte is a dilute sulfuric acid solution.

When discharging (using), the positive and negative electrodes react with sulfuric acid to form lead sulfate, and when the concentration of sulfuric acid solution drops to a certain level, it must be charged. When charging with an external power source, the electrode and solution can be restored to their original state, and they can be used again after charging.

The battery only has a charging indication, or there will be a voltage shortage prompt, the power loss will not cause a failure, and the fault light will generally not be on.

There are several reasons why a car battery loses power:1As long as the battery is connected to the car, many electrical appliances have been using electricity, but the current is very small, and the power consumption is very small and can last for many days, so if the vehicle does not drive for a long time, it is recommended to remove the negative pole pile head of the battery.

2.Even if the battery is not connected to the electrical appliance, it will have a certain amount of power loss. If the car does not move for a long time, it cannot be charged, and the power consumption is very large when it starts, so it is easy to lose power, and the battery performance will drop a lot if it loses a single power. The battery shrinks as the amount of power is used.

3.The power release of the battery has a cliff effect, that is, the discharge curve of the new battery is more linear than the back, and the battery with a long time of performance has declined greatly, looking at the indicators, the power seems to be full, but at a certain point the power will suddenly run out of power.

4.Finally, the temperature factor, that is, the weather, is also an important factor. Because low temperatures can greatly reduce the performance of the battery.

For example, the battery performance is very poor, and it is fine in summer, but in winter, as the temperature decreases, the battery performance further declines, and there will be a situation where the battery cannot catch fire.
