What should be paid attention to in battery maintenance in a car?

There are three precautions for battery maintenance, one is to check whether the battery is fixed on the car and whether there are bumps on the surface of the shell; The second is to check whether the battery cable is connected reliably and whether there is dust in the exhaust hole; The third is to pay attention to check the charging situation and quality status through the electric eye on the battery, green means qualified, black means power loss, white means battery damage needs to be replaced.

The maintenance measures and precautions for automobile batteries are as follows:

1. Always keep the battery clean and dry, and keep the ventilation hole unobstructed. When oxides appear on the plates or chucks, they should be wiped clean and coated with a little butter to avoid corrosion.

2. Do not use the starter continuously, no more than 5s each time, and use it again after two starts and breaks for 10 15s. The degree of battery discharge in severe winter shall not exceed 25%, and in summer shall not exceed 50%.

3. The battery with sufficient electrolyte shall not be placed in the case of insufficient charging for a long time and should be charged regularly, otherwise it will lead to scrapping.

4. When charging the battery, the voltage should not be too low or too high, and the standard voltage for 12V charging is generally (within the range; The standard voltage for 24V charging is (28 range.

5. The height of the electrolyte liquid level should be higher than that of the electrode plate (10 15) mm, the liquid level should be too low to replenish distilled water in time, do not replenish the electrolyte, and the non-distilled water can be replaced by rain or snow water, and do not use river water and tap water.

At present, lead-acid batteries for automobiles can be roughly divided into two types according to the maintenance situation used: maintenance batteries and maintenance-free batteries.

The lead-acid battery is composed of positive and negative plates, separators, shells, electrolytes and terminal posts, etc., in the process of use, the maintenance lead-acid battery will cause excessive decomposition of water due to its own characteristics, so that the electrolyte is reduced.

The maintenance-free battery is made of lead-calcium alloy, with less water decomposition and low evaporation, compared with the traditional lead-acid battery, it does not need to add any liquid, and the corrosion of the terminal post, wire and body is small, the overcharge resistance is strong, the starting current is large, and the power storage time is long.

For the use and maintenance of maintenance-free lead-acid batteries, the following points should be noted:

1. The battery will slowly discharge itself until it is scrapped if it is not used for a long time, so if it is not used for a long time, the battery wire should be disconnected, and the car should be started once in a while to charge the battery.

2. When the dashboard shows that the battery is insufficient, it should be charged in time.

3. The density of the electrolyte should be adjusted according to the standards in different regions and different seasons.

4. Distilled water or special rehydration solution should be replenished when the power is lost, and purified drinking water should not be used instead.

5. When starting the car, the uninterrupted use of the starter will cause the battery to be over-discharged and damaged, 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.

6. When driving daily, pay more attention to check whether the small hole on the battery cover is ventilated.

7. Check whether there is oxidation in the positive and negative electrodes of the battery.

8. Check whether the circuit is aging or short circuit to prevent the battery from shortening its life due to over-discharge.

For the use and maintenance of maintenance-free batteries, the following points should be noted:

1. The battery should not be over-discharged during use, and the discharged battery should be charged in time.

2. If the vehicle is not used for a long time, the battery should be removed or the negative wire of the battery should be disconnected. When the battery is shelved and deactivated, it should be fully charged and check the status of the battery frequently, and replenish the power in time when the voltage is low.

3. It is forbidden to use the method of short-circuit ignition of the battery to test whether the battery has electricity.

4. Always check whether the connection part is firm and whether the terminal surface is clean to ensure good contact.

5. The exhaust hole of the battery can not be blocked, and it must be prevented from being sealed by ice water in winter, otherwise the internal pressure of the battery will increase and the shell will burst accident.

6. It is strictly forbidden to place metal tools and conductive objects near the battery terminals, so as to avoid metal objects and battery terminals from colliding, resulting in short circuit ignition and burning of batteries and terminals.

Precautions; The battery should be handled gently and not skewed to prevent the electrolyte from flowing out.

When checking the density and level of the electrolyte, do not raise the instrument too high, so as to avoid the electrolyte droplets on the human body or other objects.

Car battery is one of the indispensable power for the normal operation of the car, how to avoid abnormal use, shorten the service life of the car battery, and extend its use time is a problem that many car owners are concerned about. So today, let's talk about what should be paid attention to when maintaining car batteries?

1.If the owner does not drive for a long time, it is best to power off the battery, and then start the vehicle once in a while, and when the battery is found to be in deficit, it must be charged in time. In addition, when disconnecting the battery, it is necessary to unplug the negative terminal of the battery first, and then unplug the positive terminal, and check the status of the battery when reconnecting.

2.When the ammeter pointer shows that the storage capacity is insufficient, charge it in time. The storage capacity of the battery can be reflected on the dashboard.

Sometimes on the road it is found that there is not enough power, and the engine stalls and cannot start. As a temporary measure, you can ask for help from other vehicles and use the battery on your own vehicle to start the vehicle roll, connecting the negative pole of the two batteries with the positive pole.

3.Drive a section of the road every once in a while. Vehicles are difficult to start because they cannot be left for a long time without meeting.

Even when the vehicle is not in use, the battery should be turned on every few days to ensure that the battery is always fully charged. However, cars often travel short distances and start and stop, which will lead to long-term undercharging of the car battery and shorten the service life. 20-30 minutes on the highway at a steady speed can give the car battery enough time to recharge.

4.Maintenance-free batteries should be kept with sufficient power at all times. If you use the car a lot, the battery will be fully charged.

But if you don't use the car often, such as parking for a few days without a car, the battery will run out. When starting, there will be a weak start. The headlights dim when idling because when the engine is idling, the generator is not powerful enough and if the battery does not provide enough current, the headlights will dim.

When the car is parked for a long time, you need to drive the car out and walk around for about 20 minutes to allow enough time for the battery to recharge.

The battery should be inspected for more than 2 years, and the vehicle will not open the cracked key for a long time, which will damage the battery. The battery should be inspected for more than 2 years, and the service life of the battery is 2-3 years. If the vehicle is not opened for a long time, the battery will be damaged, and the vehicle will consume power and damage itself if the battery is not opened for a long time.

Don't wait for the battery to drain the battery in the morning before charging, the vehicle must be warmed up in advance before starting, all the lights, sound and air conditioning must be turned off before the ignition, the vehicle should not start for a long time, the vehicle can be removed from the negative pole of the battery if it does not start for a long time.

These problems should be paid attention to when raising and protecting the battery of the car car

1. Turn off all lights before turning off the fire.

2. Turn off the air conditioner and stereo before turning off the fire.

3. Avoid parking the vehicle for a long time.

If you don't drive the car for a long time, you need to do a power off treatment, and if the battery loses power, it must be powered on in time.

If you don't drive the car for a long time, it is necessary to perform the punishment of power-off disposal, and if the battery loses power, it must be energized in time.

The battery should be inspected for 2 years and the width of the car should be inspected, and the car beam should not be opened for a long time, which will damage the battery. The battery should be inspected for more than 2 years, and the operating life of the battery should be 2-3 years, and more should be checked when the life is about to expire; If the vehicle is not turned on for a long time, the battery will be damaged, and the battery will be consumed and damaged by the vehicle if it is not turned on for a long time.

As we all know, the engine is the core component of the car, but compared with the car battery, it is also a very important component, because it is responsible for the start of our car, providing stable power for the electrical appliances of the car, and ensuring the normal use of the electrical appliances on the car. So how should we take care of our batteries? What to do if your car battery dies?

How do I care for my battery?

1.When we maintain the car, we can do a simple maintenance of the battery, regularly wipe off the sludge and residual electrolyte on the outside of the battery, and then wipe off the dust, oil, white powder and other dirt that are easy to cause leakage on the panel and positive and negative electrode heads, so that the electrode head of the battery will not accumulate too much white acid etching powder, and some butter can be applied, which can prolong the service life of the battery.

2.Avoid some bad driving habits. For example, some car owners are accustomed to turning off the ignition and turning off the lights without turning off the empty switch, which leads to the high automatic operation load of the space-time switch next time, which will cause long-term wear and tear of the battery.

In addition, listening to songs in the car and charging the phone for a long time after the ignition is turned off will also cause damage to the life of the battery.

3.For a car that can't be put out for a long time, the battery will be slightly reduced, which will eventually lead to difficulty or even no start in the car. This is because the battery discharges itself during a long period of time.

Therefore, it is recommended that car owners try to drive once a week for about 20 minutes each time, so as to prevent this from happening.

What should I do if the battery suddenly dies?

1.The power generated by the downhill slope is used to start the vehicle, but this method is only suitable for manual transmission models, but there is a disadvantage that when the vehicle is in gear, it will cause some damage to the gearbox.

2.Prepare an emergency starting power supply for the car. This power supply is lightweight and easy to carry.

When the car battery dies, it can be used as an emergency power source. Also, if you're going fishing or something, you can also use this as a power bank. Don't worry about the power outage of your phone, it's very convenient.

3.If the car is due to battery failure, such as the lack of emergency starting power and car power, a manual cart is also a good method. The engine is powered by the power of the wheels, but there must be several strong partners in the car, otherwise you can only wait for rescue in the middle of nowhere.

Of course, this method is only suitable for manual traffic jams.

4.Usually, prepare a jumper in the car and find a rescue vehicle. Connect one end of the red line to the positive pole of the rescue vehicle and the other end to the positive pole of the rescue vehicle.

Then connect one end of the black wire to the negative pole of the rescue vehicle and the other end to the engine block of the rescue vehicle. But bury, in this process, do not touch the body of the metal wire to prevent short circuits.

Millions of car purchase subsidies.

1. The battery needs to be checked if it is used for more than two years

Generally, the service life of car batteries is 2-3 years, for new cars'The original battery can be used for 3 years. So if your battery has been used for almost two years, be aware that its useful life may have expired. At this time, you should check more, do a good job of testing in advance, find problems and solve or replace them as soon as possible, so as to avoid the loss caused by the sudden "lying down" of the battery during use.

2. What do I need to pay attention to after replacing the battery?

New batteries may be running low on power, including those found in new vehicles, which may not be 100% charged. Therefore, after replacing the battery with a new one, or after buying a new car, it is necessary to let the engine run for a longer period of time to ensure that the battery of the grinding section can be fully charged.

3. Is there any damage to the battery if the vehicle is not opened for a long time?

Because the battery will self-discharge, if the vehicle is not used for a long time, it may cause the battery to run out, and eventually the vehicle cannot be started or the battery is damaged or damaged.

If the vehicle is not used for a long time, it is best to try to restart it every 15 days and let the engine run for about 20 minutes each time to allow the battery to be fully charged again.

<> "The correct way to maintain the car battery.

Car battery is one of the indispensable power for the normal driving of the car**. How to avoid abnormal use, shorten the service life of the car battery, and prolong its use time is a problem that many Li Shu car owners are concerned about.

In general, the service life of a car battery is 2 to 3 years, and the length of the battery life has a lot to do with the climate and the usage habits of the car owner.

Common factors that shorten battery life include: air humidity, dust, corrosion, loose or overtight electrodes, wear and tear, and damage to automotive cables.

In extreme cases, these factors can lead to battery rupture or even more serious accidents, with humidity and dust being considered the two most common culprits. Keeping the battery clean and tidy, regular inspection is an effective means to extend the service life of the car battery, but the cleaning of the car battery is different from daily necessities, and wiping it with a rag is far from enough.

During the cleaning process, the first thing to check is whether there is an open flame in the working environment, especially to pay attention to the prohibition of smoking during cleaning, and to disconnect the negative terminal of the battery from the car cable when the engine is turned off. Because the acid containing a large amount of sulfur in the car battery will produce flammable hydrogen, which is easy to occur in case of open flame, which is dangerous. Then remember to dry everything before and after cleaning to avoid short circuits.

Keeping the above precautions in mind, the real cleaning officially begins, and the specific steps are as follows:

1.Use a professional battery electrode brush or a discarded toothbrush to clean up dust and corrosion on the positive and negative levels of the battery. If you accidentally get clean-up residue on your hands, be sure to wash your hands promptly.

2.Apply petroleum jelly or lipids to the contact surface to form a protective film.

3.Carefully inspect batteries, cables, and other factors that could potentially shorten battery life.

4.Reconnect the cable and battery, strictly following the order of the positive and then negative electrodes to prevent electric shock or damage to the car's electrical system.

5.Finally, a full check is carried out to start the engine to ensure that the battery connection is working properly.
