How long will the car battery die?
The automobile battery leaks about 1% every day. If connected to a car, the minimum current of the car (commonly known as "dormant current") is about 80mA. If there is an anti-theft alarm, it will consume a certain amount of electricity. Generally, it consumes about 2~3% of the battery every day, which means that the battery will be dead in 30~70 days (the power is not enough for the system to run).
Related knowledge:
When the battery charge is less than half, that is, the voltage is lower than 13.4V, it is difficult to start the car.
If the battery voltage is lower than the rated voltage by 10%, that is, lower than 10.8V, the battery is in danger of losing power.
If the battery is short of electricity, its life will be shortened by 80%, and generally it will retain more than 20% of electricity.
The car battery fault light is on and needs to be recharged in time. You can use the charger or 1500 rpm to charge for more than 30 minutes to ensure that you can start the machine the next day.
Car battery replacement should adhere to the whole car with electricity, choose "circle" to replace the battery. If the battery is replaced directly, it will cause data loss and initialize the requirements, which is also commonly known as code matching.
What should I do if the car battery is dead?
When the car battery suddenly dies, don't panic. Check the problem step by step according to the following steps:
1. If the light and horn can still work normally, but the starting motor is weak, you can start the manual transmission car by pushing the cart. In detail, you can put in second or third gear, step on the clutch and push the cart. When the vehicle speed reaches a certain level, release the clutch and the vehicle can be started.
Second, if there is no electricity at all, there are the following emergency measures:
If you have a portable charger, you can charge it directly in the car without disassembling the battery. If you drive less and park more, you'd better buy one yourself. The price is very cheap, tens of yuan. Be sure to buy a smart charger that can switch power and stop automatically.
Cart start
Before the cart starts, it is necessary to investigate whether the road conditions at the parking position of the vehicle are suitable for the cart to start, and downhill can improve the speed. If the front of the car is uphill, the cart will be very tired and it will be difficult to improve the speed, so turn the car downhill. Try not to start the cart on the road with many vehicles and pedestrians, so as to avoid accidents caused by improper driver response after the vehicle starts. Turn on the incineration switch before pushing the cart. When the vehicle reaches a proper speed, put the transmission into gear, then quickly release the clutch pedal and refuel. Once the engine starts, you should quickly step on the clutch pedal and control the throttle at the same time to prevent the engine from stalling, and then gradually stop.
Traction start
This method is similar to the start of a big car, but the difference is that the traction of a small car is often much more labor-saving. It is necessary to use a suitable length of traction rope and fasten both ends. Before towing, the drivers of the front and rear cars should first determine the contact signals, such as honking or gesturing when starting and stopping, so as to coordinate and cooperate.
Lap initiation
(1) In any case, if there is a peer car and there is a jumper cable on the car, you can also choose to start the car by overlapping the batteries. When operating in detail, first approach the two vehicles until the jumper cable meets the requirements of connecting the positive and negative poles of two batteries. Care should be taken to ensure that the two vehicles do not touch each other, and only cables with satisfactory bearing capacity and insulation sheath are allowed. If the installation position of the power battery on the vehicle is not convenient for direct bridge, the battery must be removed with tools.
(2) Determine the anode and cathode of the two batteries and connect them with cables respectively. Pay attention to the positive and negative poles of the battery to ensure reliable cable connection. Adjust the direction of the cable to avoid the cable being scratched by the adhesive tape or fan when starting.
(3) Turn off all vehicles belonging to electrical equipment on the vehicle, start the battery position of the power supply, and let the starter run for a few minutes to ensure sufficient power. Then start the vehicle in a normal way without electricity. After starting, lightly step on the accelerator pedal to make the starter run at 2000 rpm for several minutes. Then turn on the incineration switches of the two cars, carefully remove the cables, and pay attention to avoid the collision between the positive and negative cable connectors.
Working principle of automobile battery
It uses a lead plate filled with sponge lead as a negative electrode, a lead plate filled with lead dioxide as a positive electrode, and 22-28% dilute sulfuric acid as an electrolyte. Electrical energy is converted into chemical energy when charging, and chemical energy is converted into electrical energy when discharging. When the battery is discharged, metal lead is the negative electrode, which is oxidized into lead sulfate. Lead dioxide is the positive electrode, which is reduced to lead sulfate by reduction reaction. When the battery is charged with direct current, the two poles are separated, resulting in lead and lead dioxide. After the power supply is removed, it returns to the state before discharge, forming a chemical battery. Lead battery is a kind of battery that can be repeatedly charged and discharged, and it is called secondary battery. Its voltage is 2V, usually three lead-acid batteries are connected in series, and the voltage is 6V. The car uses six lead-acid batteries in series to form a 12V battery pack. Generally, lead storage batteries should be supplemented with sulfuric acid after a period of use, so that the electrolyte insists on containing 22~28% dilute sulfuric acid.
Usage of automobile battery
Develop a prominent habit of using electricity in the car. The most important thing to maintain the vehicle battery is to develop good electricity habits, such as not listening to the radio loudly, charging the mobile phone and using the charging pump. When the car is turned off, the battery is simply dead for a long time, and the battery is dead more times, and its life will be greatly reduced.
Regular running, high-speed running. Driving at high speed on a regular basis has many advantages, not only eliminating carbon deposits in the car, but also fully charging the battery. Generally, the battery can be fully charged after driving at high speed for more than one hour, so the battery can be kept in the best condition.
Don't put the car on hold for a long time. If you don't use the car for a long time, such as 20 days or a month, you should cut off the battery line, and maybe start the car for dozens of kilometers every two weeks to ensure the normal use of the battery.
Be careful not to connect the battery directly with high-power appliances. At present, many vehicle-mounted electrical appliances, such as vehicle-mounted refrigerators, vacuum cleaners, air pumps and so on. , with great instantaneous power. Please do not use the car battery to supply power directly. You should burn the vehicle first, then connect the electrical equipment. This is a good protection for the battery.
Maintenance method of automobile battery
Don't start the car frequently. Many car owners will have difficulty starting the car in winter, so they will start it again and again. But the correct way should be: start the engine for no more than 3 seconds at a time. If the first launch fails, don't rush to launch again and again. Judging from the working principle of the car, starting the motor continuously at this time will definitely cause the battery to be over-discharged and damaged. The restart interval should be more than 5 seconds.
Predicting the precursor of battery "strike", some batteries will become very internal resistance after use, and will show the phenomenon of full charge and complete discharge. When the car owner uses the battery for about two and a half years, he should carry out routine maintenance and inspection on the battery, which can play a preventive role. Forgetting to turn off the interior lights when stopping the car is a simple mistake of many new car principals. After a night's consumption, the battery may be dead at any time and the car will not start. In this case, if conditions permit, you can try to charge the battery. If it still doesn't work, you may need to replace the battery. Try not to use CD, cigarette lighter and other electrical appliances when the vehicle is not started, and use less on-board electrical appliances during driving.
Turn off the air conditioner before turning off the engine. Most car owners are used to not turning off the air conditioner or letting the air conditioner start actively after the vehicle starts. This will cause the air conditioning system to start running actively after turning on the incineration switch of the vehicle every time, which will directly lead to the excessive instantaneous power load of the vehicle, which will cause battery loss after a long time.
Measures to avoid bulging of automobile storage battery
Avoid using high-power electrical equipment.
Because the original car battery only considers the power required by the original configuration in the car when it leaves the factory, the electric equipment added privately in the later period will increase the load of the battery, leading to the "overwork death" of the battery in advance. So try not to install and use high-power audio equipment, car headlights, car refrigerator, air pump and other power-consuming equipment without permission.
Clean the battery regularly.
Regularly clean the outside of the battery with a damp cloth, and wipe off the dust, oil stain and white powder on the panel and the positive and negative electrodes. Avoid accumulating too much dirt to cause leakage.
Avoid battery loss
Batteries should avoid energy loss. Don't use car radios, CDs and other power-consuming equipment for a long time when the engine is turned off, and don't use cigarette lighters to charge electrical appliances for a long time. It is easy to cause damage when the battery is cut off.
Influence of aging of automobile battery on automobile
The computer is locked, which is time-consuming and expensive. If the battery is so old that it is completely dead, there may be more troubles waiting for you besides letting the car lie down; The sudden stop of power supply system will lead to the sudden locking of vehicle-mounted computer and the loss of system data. At this time, only by going to the 4S store to decode can we get out of trouble.
The car is lying in the nest and people are on the road. This is an embarrassing thing that car owners often encounter, especially when they go to work in the morning rush hour or pick up people at the airport, they suddenly fall into the predicament that the vehicle is turned off or can't start normally, which can only make people sigh that "the battery should be checked earlier".
Damage the system and increase vehicle consumption. This is one of the most difficult reasons for vehicle wear for car owners. We should know that more than 70% of the power system wear comes from the lack of battery power at the moment of cold start of the vehicle; Moreover, unstable battery power supply can easily damage other vehicle-mounted appliances (such as GPS, etc. ).
Headlights are blurred, endangering safety. In the daily use of vehicles, it is generally difficult for the owner to directly detect the working condition of the battery; But with a little attention, you can still draw an intuitive judgment. For example, insufficient battery power will dim the brightness of headlights and affect driving safety at night; Especially when the vehicle is idling, if the headlights gradually dim, it means that the battery must be replaced now.
The current is unstable, affecting the quality. As for enthusiasts who buy high-end cars, they may spend a lot of money to modify entertainment equipment. If they don't enjoy the expected sound quality, don't be too busy wondering if they have spent money. Check the battery. Maybe it's this negligence that causes the high-end car stereo to fail to work properly.
The post will present oxidized white powder, which will corrode the electronic circuits buried in the engine room, leading to leakage, short circuit and even spontaneous combustion of the vehicle.
In winter, people are in a bad mood, and in summer, they go on strike. In winter, it is easy for car owners in the north to find that their batteries are a little emotional from time to time, which makes the vehicle start very tangled; In summer, car owners in the south will find that their batteries seem expensive, and they will always go on strike because of lack of electricity.

This is Ji Xian. I am right "How long will the car battery be dead?" What should I do if the car battery is dead? The working principle, usage, maintenance methods, measures to avoid bulging, the influence of aging on automobiles and the top ten brands of automobile batteries are introduced in detail. In fact, in order to achieve the best service life of automobile batteries, in addition to the parallel battery life extender to prevent vulcanization, we should also pay attention not to discharge or lose power to avoid the positive plate of automobile batteries from softening. If you often stop to listen to music or drive at a low speed for a short distance, it will take about half a month to charge the car battery, so that the service life of the car battery will be the longest, and this important part of the car battery will always be in the best working condition.
