How to maintain a car battery?

I am happy to answer your question. With the current trend of automobile electronics, more and more electronic devices are used in the car, and the battery is not only used to start the engine, but also for power supply in some. devices. , daily maintenance of the battery is essential. Here are some interview methods shared with you.

1. When you drive daily, you should first turn off the electrical appliances, then turn off the engine

When you turn off the engine, you should first turn off some electrical equipment of the car. As long as the battery is still in use, the battery will work all the time. This will not only consume power, but also accelerate battery aging. to turn off all equipment in the car and turn it off when parking.

2. Regularly clean thecar battery poles

The battery may accumulate acid-etched powder and stains during daily operation. a damp cloth Wipe off dust, oil, white powder and other contaminants that can easily cause leakage on the panel and the positive and negative electrodes. In addition, you can also apply special grease to the two battery electrodes to protect the battery.

3. Check the battery status regularly

In order to maintain the best performance of the battery, it is best to check the battery every six months to see how much energy it has stored. What is the capacity? Typically, the lifespan of a battery is around 3 years, and if properly maintained, it can last up to 4 years. But the further we go, the more the time needed to check the battery decreases.

Here are some maintenance methodsn daily batteries. I would like to share them with you. I hope they will be useful to you.

1. Make sure the car has electricity

2. Do not use a washer gun car

1. The function and principle of automobile batteries.

The car battery is a device that converts chemical energy and electrical energy into each other. According to the maintenance method, it can be divided into three categories: ordinary, low-maintenance and maintenance-free batteries. Their functions are:

(1) Providing electrical energy to start the car.

(2) When the generator is overloaded, it can help the generator to power the electrical equipment.

(3) The car battery is a large-capacity capacitor that can absorb the instantaneous high voltage generated in the circuit inside the car, thus protectingi the car's electrical equipment.

(4) In addition to providing electrical energy to the vehicle, it can also store excess electrical energy generated by the operation of the generator.

2. How to maintain the battery?

(1) Car batteries also discharge while parking, powering anti-theft modules or certain electronic devices. Daily discharge can reduce capacity by more than 1%. Long-term power loss will shorten the battery life or directly discard it. Car owners should regularly start their vehicle and drive it a certain distance, or remove the battery when parked. Negative terminal to prevent battery loss.

(2) Clean the battery terminals regularly. If corrosion occurs, it will increase the resistance value and affect normal charging and dischargingdrums. This must be dealt with in time. Check whether there is any aging phenomenon on the insulating surface of the wire harness and apply special grease to protect the wire harness.

(3) When the electrolyte level of the battery is insufficient, distilled water should be added until it reaches between the lines of upper and lower scale. Do not add electrolyte, as the battery density has been adjusted at the factory. If electrolyte is added, the electrolyte density of the battery will increase, its internal resistance will increase, the voltage will decrease, the charging capacity will decrease, and the aging of the battery plates will be aggravated.

(4) The time between starting the vehicle should not exceed 5 seconds. If the vehicle cannot start, the interval between restarts should not be less than 15 seconds. If it does not start three times, it must be stopped fornt a few minutes before restarting to avoid excessive battery discharge and damage. And if the car still does not start after several starts, the cause must be looked for in other aspects such as the circuit, ignition coil or oil circuit.

(5) During daily driving, you should always check whether the small hole on the battery cover is ventilated. If the small hole in the battery cover is blocked, the hydrogen and oxygen generated cannot be discharged. When the electrolyte expands, it will cause the battery shell to burst and affect its service life. In addition, for maintenance-free batteries, the condition of the battery can be judged by looking at the color of the observation hole. Green means the battery is good; black means the battery is low; white means the battery electrolyte level is too low; red means the battery is damagedaged.

Finally, I wish everyone a happy life!

How to maintain the battery? Keep the battery dry at all times, remove dust and mud from it to prevent corrosion from contact points and remove oxides from poles and connectors to avoid increased resistance. Avoid excessive discharge. Try to avoid leaving the vehicle for a long period of time. If you need to park it for a long time, you can drive the vehicle for a while or use a charger to charge the battery in time. The vehicle cannot start, continued use of the starting opportunity will cause the battery to overcharge. If it is damaged due to discharge, the correct method is to start the car each time for no more than 5 seconds and the interval between restarts is not less. more than 15 seconds. If it fails to start several times, the cause must be foundin other aspects such as circuit ignition coil or oil circuit. The above is my opinion on battery maintenance, thank you

1. The most important thing about the car battery is that the car cannot not be left in a powered state for a long time. for a long time, which will often lead to serious battery problems; Many people have the habit of leaving the headlights on when the car is turned off after driving at night, which will soon lead to insufficient battery power.

2. Maintain the general cleanliness of the vehicle. Some cars are parked under the trees. If leaves fall on the car for a long time, the wind may blow into the hood. If it stays on the battery for a long time, there will be safety hazards. Cover it with a car cover when parking the vehicle.

3. As the saying goeshe proverb, the car is not broken when it is running, but when it is discharged, if you park it for a long time, the battery will lose. some power.If the battery is to be parked for a long time, unscrew the primary wire from the battery. In this way, the battery will not be discharged in the off-circuit state and the damage to the battery will be reduced.

4. Many people like to listen to music while driving, which actually has no impact. However, if we still listen to music when the car is parked, the battery is exhausted. If there is no charge in discharge state, the battery will appear in power state soon.

5. For power supplies, the main “killer” is dust. If it builds up too much, it will form a short circuit condition on the battery, which will often be directly. burn the battery. Clean the contacts around the battery.

InNormal circumstances, car batteries do not need to be maintained, unless your car is not used for a long time, then you need to remove the negative electrode and charge it every time. two months. You should pay attention to normal use. If you always drive back and forth for several kilometers, the damage to the battery will be relatively significant. It is recommended to take your family for a walk to a remote place during the weekend and leave the battery. be fully charged for regular high-speed journeys. It has many advantages. It can not only remove carbon deposits from the vehicle, but also fully charge the battery. Generally, the car battery can be fully charged after running at high speed for more. More than an hour. This type of battery can maintain the best conditions. If you do not uses the car for a long time, such as half a month or a month, you should cut off the battery cable or start the car after two weeks and drive it for tens of kilometers to ensure that the battery can be used Normally. The above is my personal opinion, I hope it can be helpful to everyone

1. Turn off all the lights before putting out the flames

Some older models do not support the auto power off function after stopping the engine, so you need to manually turn off the interior lights and reading lamps before turning off engine. If you need to find something in the car or need lighting, you can use your cell phone or flashlight for lighting, so you don't turn on the reading light and forget to use it. turn off, which will result in loss of powerbattery life.

2. Avoid parking the vehicle for a long time

The battery installed in the vehicle will discharge for a long time period. long-term storage. , many car owners will find it difficult to drive the car or even the battery will be completely discharged after returning from a business or tourism trip, so it is best to drive the car once a week, and the time driving is preferable. more than 20 minutes, so that the battery can be charged while the vehicle is driving.

3. Close the windows before turning off the engine

The car window and sunroof switches are powered by batteries, so it is best to close all windows before turning off the engine, rather than closing them after turning off the engine, or even closing the windows by long pressing the lock button after leavingthe car.

Carefully check the cap area for rust. Once rust appears, use a professional cleaning agent.

During daily driving, you should always check whether the small hole on the battery cover is ventilated. If the battery cover hole is blocked, it will cause hydrogen and oxygen cannot be discharged. When the electrolyte expands, it bursts the battery shell and affects its lifespan.

If the battery is not used for a long time, it will discharge slowly. Therefore, it is better to start the car every certain period and run it for about 10 minutes. more than 15 minutes to charge the battery, the battery has a certain lifespan and needs to be replaced after a certain time.

1. It is strictly prohibited to operate or place thehas battery in a low power state. Power loss state (battery voltage drops 20%) means the battery is not charged in time after use. In a depleted state, the battery is prone to sulfation. Lead sulfate crystals adhere to the plates and block the ion channels, causing an increase in the internal resistance of the battery, insufficient charging, slow charging, and a decrease in battery capacity. The longer the battery is left unused, the more severely damaged it will be until it is discarded. 2. When the battery is not in use, it should be charged once or twice a month to keep it in good condition. 3. When not used for a long time, the battery ground wire should be disconnected. 4. The battery charging current should not be too large, and the charging voltage should not be more than 20% of the battery voltage.e the battery. It must be charged at a current of one twentieth of the battery capacity and charged continuously. 24 hours

Battery, also called storage battery, is a type of battery whose working principle is to convert chemical energy into electrical energy. The normal lifespan of a car battery ranges from 1 to 8 years, which depends a lot on the condition of the vehicle. If the vehicle's generator is recharged normally and the electrical devices have no leaks or grounding, it can in principle be used for more than 3 years. If you feel that it cannot be charged or the starter is weak and the headlights are visibly dimmed, you should remove the battery and charge it with a charger for 12 to 24 hours. If it still does not work and the vehicle has been charged. used for a long time, you should consider replacing the battery.

SIf the battery is not used for a long time, it will discharge slowly. Therefore, it is better to start the car at regular intervals and run it for longer periods of time. 15 minutes to charge the battery. It has a certain lifespan and must be replaced after a certain period.

PS: When the car lights are dim and red, the horn is not loud and the starter is weak, the battery should no longer be used and must be charged immediately. During use, you should try to maximize the charging possibilities and always work in a fully charged state. When using the battery in winter, you should always keep it fully charged to prevent the electrolyte from freezing due to its low density, which could damage the battery.

The battery plays a big role in the use of the car. If she cannot provideenergy normally, problems will occur in the engine and circuit system of the car. Therefore, car owners usually take good care of them to avoid the dilemma of the engine not starting or the car suddenly stalling midway. In fact, car owners only need a minute or two to service the battery every time they check the engine.

Here are some tips for maintaining the battery yourself: Tips:

1. Use a cloth wet to scrub the exterior of the battery to remove dust, oil, white powder, etc. of the panel and the battery heads (i.e. the positive and negative poles). Wipe away dirt that can easily cause leaks. If the battery is frequently scrubbed in this manner, white acid-etched powder will not accumulate on the battery's cell head and its lifespanlife will be longer.

2. Open the battery water filler cap and check if the water level is at the normal position. Generally, there will be upper and lower limit marks on the side of the battery for your reference. If it turns out that the water level is below the lower mark, distilled water should be added. If distilled water cannot be obtained immediately, filtered tap water can be used in an emergency. Don't add too much water, the standard is to add some in the middle of the top and bottom markings.

3. Check if the battery charges normally. If you have an ammeter, after starting the engine, measure the voltage at both poles of the battery. It must exceed 13V to be considered normal. If you find that the charging voltage is too low, you should ask a professional to check the charging system. If there is no amthree-function father meter, you can carry out a visual inspection: after starting the engine, open the battery water filler cap and see if there are bubbles in each small cell. The normal situation is that bubbles will continue to come out of the water, and the more oil comes out, the more oil will bubble; If you see no bubbles, there is probably a problem with the charging system. Particular attention should be paid to the fact that hydrogen will be generated during this inspection, so do not smoke during the inspection to avoid the risk of explosion and fire.
