The epidemic is so serious that the cars in the community will not drive for a long time. How long will the battery be dead?

My car has not been driven for more than 20 days. Mine is a Chery car, more than 50 thousand, but it was successfully ignited once. I think it should be no problem for the local train to leave for about 40 days. But if it is an old car and the battery is aging, it is best to light it once every half month. In case of long-term power failure, it will be embarrassing.

The Year of the Rat started well, but the rampant epidemic disrupted almost everyone's life. Reserved programs for Chinese New Year every year: cancel visiting relatives, cancel dinners and cancel travel. Even "driving out for a walk" has become a very dangerous thing. In the case that the date of returning to work has been postponed repeatedly, staying at home has become the most responsible thing for yourself and others, and it is also a contribution to the country. But at the same time, idle cars in the garage have become hidden dangers in the hearts of car owners. I heard a long time ago that the car didn't meet for a long time and the battery didn't catch fire. This situation does exist, but with the current automobile technology, there is no need to worry too much. Today, Ma Lao's article will tell you in detail what you should pay attention to when parking vehicles for a long time.

First of all, let's be clear: the car is not made of paper, and it won't have any particularly big impact if it doesn't start for ten days and a half. First of all, everyone is most worried that the car battery will be dead after a long period of parking, so how long will the car actually be dead?

In today's car design, even if all electrical equipment is turned off and the ignition switch is turned off, the battery still discharges less. This is easy to understand, because the electronic control unit and anti-theft system on the car still have to protect the car. But this kind of discharge is very weak, so we don't need to worry too much. A brand-new battery with excellent quality can usually ensure that the vehicle can be safely placed for 3 months without power failure. However, considering the owner's battery situation, it can basically be parked for 30-45 days, that is, more than a month. Judging from the fact that half a month has passed since the Chinese New Year, most car owners' cars are safe even if they haven't moved once.

Of course, there will be some special circumstances. Some car owners stop their cars for a week or so and they will run out of power. It is ruled out that the hanging battery itself will die, and there will generally be some equipment that "steals electricity". In other words, after the car is turned off, the battery is still consuming a lot of power. This situation is probably caused by some equipment installed later, so the owner can check whether these things are consuming the electricity in the battery first.

Speaking of which, I have a little suggestion. Most repair shops have not resumed business recently. If you are not at ease, you can choose to buy an emergency power supply online after the courier is restored, in case of emergency.

As mentioned above, the batteries of most vehicles can be used for more than one month, but I believe that many small partners have been notified to continue to postpone their work recently. In this case, it's really time to do something for the car in the garage. In fact, the practice is very simple. It is recommended that ordinary car owners start the vehicle once every half month, keep the speed above 2000 for half an hour, and basically charge the battery. Of course, if you are a car owner who has no confidence in your car condition or has not changed the battery for several years, it is recommended to change it every five days to make you feel at ease. More importantly, when parking for a long time, don't park your car on the slope. If you are too lazy to move, you can also cut off the negative electrode of the battery directly. In that case, it is no problem to stop for half a year.

Of course, in the end, I still want to remind everyone that even if the distance from going out to the car is not long, you should wear a mask to protect yourself when you go home and wash your hands frequently. Only by protecting yourself and your family can you better protect your car.

If the car is parked for a long time, the battery will automatically discharge, and when it is used again, the car may not start. So how long will it take for the car to stop before the battery is completely dead?

Now even if the ignition switch is turned off and all electrical appliances are turned off, the battery will still have a weak discharge. This is mainly because the electronic control unit and anti-theft system on the car continue to work after the engine is turned off, which needs to consume a certain amount of electricity. But this power is relatively small, generally less than 30mA. In this case, the 60Ah battery will be completely discharged within 2000 hours. In fact, many batteries can't reach the nominal capacity, and this time is much shorter. Generally, the battery will be completely dead in about 1000 hours. As for some cars, they ran out of power after a few days. One possibility is that some parts of the car are leaking electricity, such as a light that is always on. In addition, when driving is stopped, the battery capacity decreases or the power loss is serious.

Some people say that if the battery is disconnected, will it not discharge? In fact, in this case, the battery will also discharge. Now the scientific name of automobile battery is "lead-acid battery", which has the characteristics of self-discharge, that is, if it is not used there, the power will gradually decrease. The amount of self-discharge of the battery is related to the material and manufacturing quality of the battery. Generally, the more advanced the battery, the smaller the self-discharge capacity. In the early standard, the self-discharge rate of the battery was below 1%, so the battery was completely dead after three months. Now the battery technology is more advanced, and the materials used can greatly reduce the self-discharge rate. Generally, it will be fine for half a year.

Here is a little common sense: the so-called battery is completely dead, not because the battery voltage drops to 0V, but to10.5 V. At present, the nominal voltage of automobile battery is12 V. In general, the voltage measured under no-load condition should be between12.5 ~12.8v. The rated capacity of a battery means that a fully charged new battery is continuously discharged at an average temperature of 30℃ at a discharge rate of 20h until the battery voltage drops to10.5v. For example, "60" in 6-QA-60 is the rated capacity, which is obtained by continuous discharge at a current of 3A for 20h, and the battery voltage drops to/kloc-0. Below 10.9V, the car can hardly start. Judging from this parameter, a car with good battery technology can be stopped for 30~40 days, and it can be started by itself. It's hard to say after this time. If the battery technology is not in good condition, or there is no electricity when driving stops, it may not work for half a month.

In order to avoid the battery loss of a car that has been parked for a long time, the best way is to start it regularly and let the car's own generator charge the battery. If the battery is in good condition, start it once every half month and run it for about half an hour at a speed of about 2000 rpm, the battery can basically be completely discharged. If the battery technology is not in good condition, it is best to start it once a week. Unplugging the battery cord is not recommended now. On the one hand, the car's anti-theft system stops working after disconnecting the cable, and the car is at risk of being stolen or damaged. On the other hand, after the battery is cut off, many settings on the car disappear and need to be reset in the future. Even some cars can only be started after the power is cut off and the engine control unit system is reset with a special computer, which is not worth the loss.

Under normal circumstances, it is no problem to decentralize for three months. Don't come out and ask questions for ten days and a half [cool drag] [cool drag] [cool drag]

In the process of long-term parking, the continuous discharge of the battery can easily lead to the loss of power of the battery, affect the next vehicle start-up, and directly lead to the damage of the battery-every overdischarge will cause irreversible damage to the battery.

Therefore, during parking, you can start the vehicle every few days and let it run at idle speed for more than ten minutes. This will not only fully lubricate the engine with engine oil, but also charge the battery to prevent excessive discharge of the battery.

2. Appropriate displacement

If conditions permit, vehicles parked for a long time can still travel a certain distance regularly. Even if you just drive slowly in the parking lot for more than ten minutes, you can charge the battery on the car, fully preheat and lubricate the engine and transmission, and avoid local tire deformation caused by long-term parking. Therefore, even if you can't go out, you can let your car go out for a walk in the community regularly. hope this helps

You know everything about cars.

It can be seen that the subject is worried about the state of the battery, and similar problems or embarrassment will indeed occur in reality. However, under normal circumstances, parking for 1-2 months should be no problem.

Can be considered from the following aspects:

Of course, whether a stationary car is short of electricity or not, the most important factor is the length of parking time.

There is no absolute data about this factor, but there is usually no power loss after parking 1 month. I stopped for 3 months and didn't start it, but the battery can still support smooth ignition.

However, whether there is insufficient power depends not only on the length of parking time, but also on the state of the battery itself. For example: Is the battery fully charged? Is the quality of the battery itself or the storage capacity? What is the battery life (life)?

In addition, we should also consider the actual situation, including whether to cut off unnecessary power consumption and whether the environment is extreme.

Some interviewees also mentioned that the 60Ah battery will be completely discharged within 2000 hours. However, when the actual voltage drops from 14.5V to 12V, the engine can no longer be started.

At the same time, automobile power consumption increases in winter. If the car battery has been used outdoors in the northeast for more than 3 years, once the car stops driving for a week, it is indeed possible that there will be no electricity.

Therefore, it is suggested that the owner start the vehicle regularly according to the actual situation, and step on the engine speed above 2000 rpm for 3-5 minutes to charge the battery to avoid feeding. (Note: After starting, the charging speed is very slow at idle speed without a fuel filler. )

Generally, the generator battery in our unit will be dead after three years, and the battery will be fine within one year after two years.

Any car parked for a long time will produce some invisible internal corrosion loss, but you have not detected it. Particularly vulnerable is the corrosion of battery and engine circuit connector.

Battery damage: the battery is most likely to be damaged after driving for hundreds of years. After the same battery is put into use, if it is left for half a month, sometimes once every few months, the service life of your battery is often less than half that of normal daily use. Under normal circumstances, you can change the battery if you use the car for more than 654.38+10,000 kilometers every day. And you can't turn on the battery of 3140,000 km for two and a half years even if you stop the car frequently. In particular, which batteries have battery liquid is more obvious.

Internal loss of engine: Because the lubricating oil in the engine can't stop for a long time, the exposed part of the upper part will rust and corrode, which will reduce the sensitivity. Under the same premise, the oil consumption will increase, and other circuit connectors will also absorb water and rust.

Proper maintenance: Your car should be started every few days for the engine to warm up once every two to three minutes, so that the engine can run normally once the battery power is used, preheating all parts of the fuselage and getting lubrication once. Just like humans do morning exercises every day to keep all parts sensitive, let your car be maintained once in operation and the engine, battery and circuit be maintained once in normal activities, thus prolonging the service life of your car. leave

When you want to open it, you can remove the zero line and connect it. This will not do any harm to the battery, and the power consumption will be less. It's very simple, just a small No.8 wrench.

The epidemic is so serious that I have to stay at home even if the battery is dead. Hello, everyone, I'm fine!

Come on in Wuhan!

Come on, China!

Overcome the epidemic!
