How to clean the car engine to improve performance

Found in the auto repair factory repair, car washing people in a continuous line, but few people clean the engine. Said engine is the car's "heart", so clean the engine is also very important, you can use the Auto diagnostic tool to check whether the engine is good, to avoid security problems.

Due to the use of the car environment is very complex, the engine used for a period of time, into the engine room of dust and impurities in the engine surface carbon and other harmful substances, if long time does not clean up these harmful substances, it will be transformed into sludge, penetrate the surface of the engine, will not only cause rusting metal parts, plastic parts deformation aging, but also lead to engine power reduced and fuel consumption increased, and even produce a variety of oxidation due to damage to the engine, if you are unsure, you can use Launch X-431 PAD and Launch X431 V Pro to be checked.

Therefore, to achieve the objective of saving, it is necessary for the engine regularly cleaning.

Cleaning the engine can ask the professionals, you can also do it yourself by following the procedure performed. First Auto Electric mask with plastic film, then the film with a wet towel on top of the lid to prevent high-pressure water rushed into the distributor, causing the car difficult to start. By the engine side from top to bottom will be attached to the class dirt engine and engine room side appearance rinse with water cannons; next engine external cleaning agent evenly sprayed around the engine and engine compartment.

Cool for about three minutes, with a fiber brush to clean all the parts that can reach the engine room, and rinse with water cannons quickly brushing off the dirt. Then external engine cleaner sprayed on engine surfaces (steps ibid.). Until the engine looks clean. Finally, rinse the engine with a wet towel and dry machine with hands REACH dry.

In addition, proper selection of some gasoline additives products can also reduce carbon deposition engine oil produced, when cleaning, avoid the time-consuming, in a timely manner use the Autel MaxiSys MS908 and Autel Maxidiag Elite MD701 auto tools, to improve the performance of the car there is a certain Help.

Exhaust smoke color can diagnose automobile problems

Automobile exhaust is the biggest factor in air pollution, in daily use the car, there may be too many people do not pay attention to their own car exhaust? However, the exhaust also contains more colors of automotive information in it, we can color from exhaust or OBD diagnostic tool to determine the car whether have problem. Look at the different colors represent exhaust what kind of information it.

White smoke
If you find smoke coming from the car, there may be a cylinder head gasket or engine damage caused by low temperatures. The former due to the cylinder head gasket is damaged cooling fluid into the combustion chamber, not only reduces the quality of the mixture, and the exhaust pipe into steam white smoke, then the need to replace the gasket; while the latter is due to the engine is cold the combustion chamber, with drops of water on the inner wall of the intake manifold, etc., together with a mixture combustion exhaust white smoke. In this case only improve vehicle temperature.

Blue exhaust smoke
If the car's exhaust emissions out of the blue, then you have to pay attention, because the car is likely to burn oil, and some brands of cars to a lot more to look at. If this phenomenon is best to check where the car round in the end there is a problem, you can use Autel MaxiSys Pro MS908P and Autel MaxiDas DS708 diagnostic tool for testing, early detection of problems will not cause too much damage to your car.

Generally because of the following reasons: the cylinder wall and the piston gap is too big, too much oil into the cylinder; oil sump inside adds a lot of oil fleeing into the cylinder; fleeing into the high-temperature gas cylinders inside the oil pan, so contaminated oil deterioration, thinning, affecting lubrication.

Black exhaust smoke
When black smoke exhaust pipe, usually burning gasoline over the car engine, cylinder gasoline mixture components beyond the normal level. You can use the Launch X431 Diagun III and Launch X431 V+ Pro3 diagnostic tool to check.

Generally because of the following reasons: air filter is dirty, inadequate intake; carburetor out of order; no carburetor EFI car, it may be contaminated oxygen sensor in the exhaust pipe, unable to gas distribution The computer provides the correct information. These problems will lead to carbon deposition valve affect the tightness of the combustion chamber, resulting in decreased engine power, resulting in decreased vehicle power, sluggish acceleration.

How to timely discovery brake failure

For brake failure, we may only appear in the braking force of brake or abnormal noise will be found. If you are traveling at high speed and other conditions, it is very dangerous! In fact, we usually use the Auto diagnostic tool you can determine the brake system problems, and these details are likely to be ignored for everyone.

First, when the brakes shudder
This situation occurs mostly in old car, because the use of wear, brake disc surface roughness has a certain degree of misalignment. It is proposed that, as the case opt lathe sanding disc technology, or replace the brake pads.

Second, when the brake quickly stopped, the steering wheel will always to the side deflection
In fact, this situation is what we called "partial brake", the main reason for the failure is about the brake system Cylinder uneven forces on the brakes caused. And in the process of moving due to the rotation speed brakes, wheel cylinder uneven role in the fast friction difference is very small, we can hardly feel it. But when the vehicle stopped quickly when the difference is obvious, that the speed of the wheel stopped on one side of priority, the steering wheel will deflect. This may need to Launch X431 GDS and Launch X431 V Pro tools to detect.

Third, driving need heat 10 minutes before the brake force
Is provided by the engine brake system pressure to promote calipers grip brakes, or push the brake drum friction brakes. So like the above conditions, may provide pressure transmission pipelines loss of pressure occurs, resulting in not timely provide braking force. This situation should be checked at the pretext of the vacuum booster hose and brake master cylinder engines have cracks or loose condition.

Fourth, the brakes do not return
Step on the brake pedal, the pedal does not rise, no resistance, a phenomenon that the brakes do not return. Need Autel MaxiSys Mini MS905 and Autel MaxiSys MS908 tool to determine whether the brake fluid missing; whether the brake wheel cylinders, pipes and joints leak; whether the master cylinder, slave cylinder parts damaged.

How to maintain the vehicle fuel system

The fuel system is an important source to provide power for the car to run, a lot of cars with the failures are due to the fuel system is not working smooth, so how to maintain good vehicle maintenance in the fuel system is also an important part of, and in accordance with OBD diagnostic tool test results to distinguish fuel system maintenance methods will be slightly different. According to different engine fuel, the fuel system can be divided into gasoline and diesel vehicles, they should pay attention to what in the maintenance of the process?

Gasoline vehicle maintenance
Data show that: the 50% gasoline engine failure is caused by the fuel system, and the faults of fuel system and about 50% are caused by unclean because of fuel, therefore, How to remove the fuel oil in the water is an important part of the maintenance of diesel vehicles.

Gasoline will have some water, these are some of the extraction of water produced during some are generated due to external factors. At normal temperatures, the fuel may dissolve some moisture on their own, but in the winter the temperature decreases, the water solubility of the corresponding smaller, the excess amount of water will be dissolved together. The proportion of water is more than oil, it will slowly separated out, stay in the oil or filter the bend, causing the oil supply is not continuous. When the temperature is below the freezing point of water, the water will freeze coagulation, causing oil is not continuous.

In addition, gasoline, water will corrode and destroy the fuel supply system components. Therefore, we must timely use of Launch X-431 PAD and Launch X431 IV GX4 Master tool to effectively remove the fuel oil in the water, you can help the effectiveness of some detergents.

Diesel car maintenance
Diesel, for example, diesel fuel contains paraffin, which was dissolved at normal temperatures in diesel, and serves as lubricating oil and diesel fuel pump nozzle tip. In the winter, large temperature difference between morning and evening, and sometimes sudden cooling, paraffin will crystallization, thus crystals of various units together and form a "paraffin crystallization network" This network extends to all of the liquid, the complete control of diesel, resulting in Diesel loss of mobility, clogged filters, affecting the normal oil supply.

Once this phenomenon, the old traditional way is to spray the tank with water, you can make diesel fuel temperature, paraffin reintegration into diesel, but this method is not only time consuming, but can not completely dissolve paraffin diesel fuel, particularly paraffin oil pump and filter is inside. In this case, some people will be blended with gasoline or ethanol in diesel, used this method to solve the problem. But the engine oil system will cause a lot of negative effects. Such as excessive wear on the pump nozzle and fuel system components for corrosion.

The correct approach is actually very simple, as long as you join in gasoline or diesel fuel alcohol into a dedicated high-tech formula additives can, using Autel MaxiSys Pro MS908P and Autel MaxiSys Mini MS905 tools to detect. Meanwhile, in order to better conserve your car, maintenance of good fuel system, a method of maintenance of the regular cleaning is also very important.

Cars common fault and repair methods

In the long-term use of the car will be some glitches, especially tires, fuel, brake system is the most prone to security risks. How that happens should deal with it? If you use Auto diagnostic tools, it is easy to solve this problem without having to go to the repair shop testing.

Troubleshooting I: a puncture.
The tires are most likely to be worn and damaged areas. Especially when walking the mountain will always be stones or nails puncture the tire, many owners in order to save trouble, go to roadside repair shop repair about to continue on their way, and in fact, this method can only be a temporary remedy, when running at high speed will have the very big safe hidden danger. Recommendations the owner to find professional auto repair shop for repair in the repair shop, because the professional shop have car diagnostic tools, and repair will be more secure with special heating after vulcanizing machine.

Troubleshooting II: fuel consumption have increased significantly.
After a period of time in the car, many owners will find that fuel consumption increased by 10% between then more than this in the offing. In fact, the fuel consumption by up also indicates that there has been a potential failure of the vehicle. This is the first thing to understand the reasons for increased fuel consumption, you can use the Launch X431 V Pro and Launch X431 Diagun III tools to detect and then to be addressed. Factors leading to increased fuel consumption are many. For example, the clutch slip number of revolutions of the engine will be lost, resulting in increased fuel consumption, the need for timely replacement of the clutch pressure plate and drive wheels.

Troubleshooting III: brake failure.
Brake failure include: brake pedal stroke is too large, the braking action is slow, and even loss of braking efficiency is low, increase braking distance. In this regard, there are three troubleshooting methods. Continuous brake pedal, pedal gradually increased and flexible feel, but when you pause for a moment and then pedal is still low, there is air in the brake system, exhaust brake system response time. Foot brake is not working, but when the brake pedal several times in a row tread with good results, the brake pedal free travel is generally too large or brake gap is too large. Pedal free travel should be adjusted, and then check the brake clearance, if necessary brake repair disintegration.

For the car appeared glitches, the owner must not be ignored, it is a reminder of the existence of your vehicle invisible faults, timely resolution or use Autel Diagnostic Tool, not only to ensure traffic safety, but also to extend the life of the vehicle. So, please take it seriously.

How to repair the fuse circuit in electric vehicle

Electric vehicle mainly consists of three parts electric drive systems, power systems, and auxiliary systems, electric vehicle systems the main circuit power supply system needs to be installed to protect high-current fuses to ensure timely primary line short circuit cut off the power, you can use auto diagnostic tools to detect and avoid damage to the battery and prevent the vehicle from overheating circuit caused the fire and other accidents.

Power supply system includes a battery, power management system and charger, and battery power system protection to avoid damage when subjected to a short circuit is particularly important during the battery protection fuse choice when you need to know the following use conditions for proper Fuse Selection:

a) the maximum system voltage value

b) rms current in the primary circuit

c) overload current and frequency and time overload

d) After the failure of the entire loop time constant L / R

e) the expected short-circuit fault current size

According to the current use of the electric vehicle industry fuses, maximum system voltage is 700VDC most models are generally less, there are a few models will be slightly higher than this voltage, fuse protection for the battery can be divided into two kinds of 500VDC and 700VDC Lord, the current level of more to 200A ~ 400A.

A50QS and A70QS quick fuse is a fuse to protect the use of electric vehicle batteries, which has a small, easy to install, fast breaking, anti-overload and other characteristics, safety, full compliance with the requirements of electric vehicles and conditions.

In electric vehicles the main circuit box and a high-voltage power distribution, its output is mainly connected to the car auxiliary power systems, power distribution inside the box under normal circumstances would include electric heating fans slip, air-conditioning compressor branch, DC / DC slip and slip charger.

This 4 support on the road, to be installed on each branch circuit protection fuses aimed at each load short-circuit protection circuit can be promptly cut off the power to prevent a vehicle fire. This line protection fuse several choices available, especially air conditioning branch fuse choice is particularly difficult, because there will be a large influx of starting current instant start when the air conditioning compressor, if often fuse according to the general selection method occur during normal use of air conditioning fuse malfunction, affect the use, so the air conditioning branch fuses for overcurrent must be considered, leaving an appropriate margin, to avoid false choice. If the primary use of Launch X431 V Pro and Launch X431 Diagun III in the main circuit to detect battery protection, to avoid traffic accidents.

How to solve the automotive air conditioning odor and refrigeration poor

Automotive air conditioning system is mainly based fluoride as the medium through the system pressure transformation, to reach refrigeration purposes. It consists of the evaporation tank, an expansion valve, a compressor, a blower, a condenser, a drying tank and lines. Evaporation tank is working in air conditioning systems work properly in cold environments encountered relatively hot outside air will produce water, which is in the evaporation tank structure, design outlet truth; wet environment evaporation tank and ventilation ducts and dust on the surface provides a breeding ground for mold and fungus favorable conditions for mold and fungus will soon multiply to mold and fungus group group of organisms that produce rotting smell that smell will open with the air conditioning, mixed in the air which, contaminate the entire car interior, occupants often make people feel uncomfortable, but also people have severe dizziness, chest tightness and discomfort. Early use of OBD diagnostic tool that can identify and solve such problems in advance.

Auto repair industry in order to solve this problem, is often demolished evaporation tank cleaning surface evaporation tank in order to achieve this approach fundamentally eliminate the odor, but every once demolished, they need to put fluoride, fluorine and other installation and processing a series of processes, cumbersome and technical difficulty, and low labor productivity. Because evaporation tank often work in a wet environment, and humid environment can easily produce mold, just to clear the air conditioning mold, over a period of time may have odors occur.

In addition, the automotive air conditioning systems as well as common problems and slight leakage of fluorine refrigerant adverse phenomenon, which also adds a lot more difficult to repair, Launch X431 V+ Pro3 and Launch X431 IV GX4 Master automotive tools can be easily resolved.

Automotive air conditioning system, air conditioning piping in power fluoro circulating from the compressor, the compressor lubrication oil is accomplished by fluorine. In the pipeline, together with the fluorine fluorine oil circulation to the entire system, which directly affect the flow of circulating air conditioning cooling performance, fluorine and fluorine oil for a long time at high temperature and high pressure and low temperature and pressure in the changing environment, coupled with the compressor work long hours under wear metal debris, etc., will produce gum and other deposits, some of these sediments are filtered out, part of the precipitation in each pipe, a small amount of the deposit does not affect the air conditioning cooling performance, but the deposition increasing material will affect the circulation flow rate of fluorine, which affects the air conditioning cooling performance. Air conditioning maintenance, we exclude the circuit, mechanical, pressure, temperature (including engine temperature) and fluorine and other reasons, the air conditioning refrigeration is still bad, we can use Autel MaxiSys MS908 and Autel MaxiSys Mini MS905 tool, the problem would be easily solved .

How to maintain the car battery

Battery plays an important role in the automobile use process, if it can not supply normal, car will not start running, while the car's power consumption in winter than in other seasons is much greater, and the battery is also afraid of low temperature, low temperature battery electrical capacitance is much lower than the normal temperature. So after entering the winter, special care for the battery is quite necessary, the battery life of about two years, if you use OBD Diagnostic Tool to check and timely care can prolong life.

First, external battery with a damp cloth to wipe it again, the panel, on the stigma (ie, both positive and negative poles) of dirt, oil, white powder and so easy to wipe clean the dirt caused by leakage and apply special grease to protect trailer coupling, to prevent corrosion.

The second step is to check the battery electrolyte leakage or deformation phenomenon. Some models are equipped with all maintenance-free battery, relevant or labels, do not disassemble the battery for this, if there is leakage, deformation of the phenomenon, it is best to go to the pits to solve. Maintenance-free battery life of about two years, expired on the use of Launch X431 Diagun III tool to check the battery voltage load voltage and starting performance, promptly replace if necessary.

The third step, if the car is parked in the open air or cold a few weeks do not, you should remove the batteries, stored in a warmer room, to prevent freezing damage to the rear battery self-discharge. When the ambient temperature is below minus 10 degrees, fully discharged battery will freeze, you must thaw the frozen processed before charging the battery, or directly charging may cause an explosion. If this happens, it is best to use a professional car repair small current slow charging stations.

So, in fact, battery maintenance is not difficult, you can try to use the owner Launch X431 GDS and Autel MaxiSys MS908 diagnostic tools, car to do maintenance on a regular basis, to extend its working life.

Car Remote Control Common Problems and Maintenance

The remote control of the car has not only brought the convenience for people, but also some problems may exist. Many car owners may not pay enough attention to the car remote control, which will lead to safety hazard both for your life safety and property safety. In view of it, with the help of a kind of OBD Diagnostic Tools, it is sure to be effectively avoided by making a full checking for your car including the remote control. Below are some common problems and the solving methods for the car remote controller.

1. No response with the remote control

If the indicator light of the remote control is not bright or dark after pressing the button, it may be the remote control battery is insufficient. After changing the battery, if still not bright, you should check whether the positive and negative polarity of the battery has been installed backwards and whether it has a good contact with the soleplate. If no problems with the above checking, and still not bright with the indicator light, then you should check whether the button can work well. If there is response with the indicator light when pressing some buttons, while no response with other buttons, it is more likely that the button has been damaged, or the remote control damaged. In fact, you can easily make it by using a Launch X-431 PAD Auto Scanner or an Autel MaxiSys MS908 Auto Diagnostic Tool to do a full checking for your loved car and without too much trouble.

2. Sometimes unable to control the door of your car

First you should make sure whether there is problem with the remote controller with the above description. If no problem with the remote control, and it appeared after changing a new battery or guard against theft system components, you should match a new remote control according to the fixed program, and not all models need to be matched, different models have different rules. If there are two remote controls, you can first test whether the other one can work well, if there is response, it may because the password of the first one has been lost, and need to be matched. If it still can’t work after matching, there may be problems with the receiving host or the transmitting antenna. And if the host of the remote control is blocked or there is strong interference source, the host will not correctly receive electromagnetic waves from the remote control, and can't control central door lock.

3. Too close effective distance when disturbed with the remote control

If this appeared after a period of using with the remote control, it may because the battery is at a low power. If sometimes far and sometimes near with the effective distance, it may be the influence of the surrounding environment. If the host of the remote control is blocked or disturbed, this kind of problem will also appear. For example, the bursting disk will have the blocking function for the host of the remote control, as well as the other electric equipment in your car.

Well, if you still have problems with the maintaining the car as well as the remote control, we sincerely suggest you to go for a Car Diagnostic Tool Online Store before driving, so that it may be much safer for you. More information about the car diagnosis please stay tuned for our later news on our website.

When the water temperature of your car engine is too high, you should immediately pull over and shut down your car, and then waiting for rescue a trailer. When driving on the highway, you should stop your car at a rest area as far as possible, or at the emergency lane. Please note: Open the air conditioning hot air when necessary. Though it may be too hot inside the car, it will effectively lower the temperature of the engine.

DIY Inspection and Site Remediation
1. Check the engine compartment pipeline, water tank, and whether there is leaking at the bottom of the car.

2. Check the antifreeze storage pot of liquid level with the help of a kind of tool for diagnosing your car, such as the Launch X431 IV Full System Diagnosis Tool and the Launch X431 Diagun III Automotive Analysis System. If finding out lacking of antifreeze, you should be go to the nearest car wash shop, gas station or comprehensive supermarket to buy antifreeze as soon as possible.

3. Timely supply according to the current consumption of antifreeze speed in order to arrive at the repair shop with safety. When at a n emergency, you can use pure water supplement, but don't try "mineral water" and "natural water", and after that, you must go to a garage or 4s store to perfusion antifreezing solution as soon as possible, and to adjust to the correct concentration of antifreeze.

4. If you are not sure about the correct reason, we suggest you to use the Car Diagnostic Tools before driving or take the advantage of the rescue trailer service, and move your car to the repair station or 4s shops to do further inspection and maintenance.

Spare Tire Maintenance and the Changing Method

For most of car owners, the spare tire is probably the one of the most unusual objects of a car, in view of it, when doing the tire maintenance, they tend to ignore to test and maintain the spare tire. Little imagine, even the spare tire is not commonly used, it often plays an important role at a crucial moment. Well, how to make a full checking and maintenance for your loved car? We sincerely suggest you to go for an OBD Diagnostic Tool Online Shop for help, where there is sure to be kinds of tools that you can choose to diagnosis your car, as well as will save more money for you than having your car checked in a repair store.

Regularly check whether there is wear
Usually, during the maintenance or before driving, few car owners tend to check the spare tire of their car, which makes it evaded, and hardly to play an important role at critical moments. In fact, the role of the spare tire is crucial, especially at long-distance driving at a high speed.

In general, as to the testing of the spare tire, it mainly includes checking the tire pressure and whether there is abrasion and crack. And you can make it with the help of a kind of Car Diagnostic Tool, such as the Autel MaxiSys MS908 and Launch X431 V Pro Automotive Diagnostic, etc. Before the tire reached up to the wear mark line, you should replace the tires as soon as possible. If there is a tiny crack at the sidewall, you can not use it to run long distance or at a high-speed driving, because the tire is thinner, high-speed will make the tire flat.

When using tire, pressure should be adjusted
In order to keep the shape and the use, when storing a spare tire, it is usually different from the common used tires on the choosing of the pressure. In general, the low pressure tire is between 2.0 to 2.5, while the spare tire is between 2.5 to 3.0, so it is not qualified, after changing the spare tire, you should look for professionals to adjust the air pressure, otherwise, it can not be normal used.

Moreover, the spare tire should not be used for a long time to replace the common used tires. Because a long time use may have a certain influence on the vehicle braking system, steering system and suspension system, as a result, it will bring huge hidden trouble for driving safety.

Frequently changed
Many car owners will often encounter such a situation: After the puncture, they want to replace the spare tire, but found the spare tire has been serious aging after placed over the years, and already a waste tire. This is mainly because the tire belongs to rubber products, too long a storage time will appear the aging phenomenon. In general, tire aging period will be 4 years or so, therefore, after four years, the spare tire should be replaced.

Tips: How to change the spare tire?
Step 1: Lift up the car with a jack, before the tire divorced from  the ground,  fasten the tighten nut the of the wheel.
Step 2: Continue to lift up the car with a jack after fastening the tighten nut, and after the tire has been fully separated from the ground, remove the original tire of your car.

Three kinds of methods to solve the problem of automobile horn

Speaker is a device frequently used while driving, like Auto Diagnostic Tool for the mechanic is the same, if the speaker appear problem, it will be very convenient when driving. Sometimes honked the horn, very hoarse, and even a little voice at all. what causes it?

Let's take a look at how the horn works. When you press the horn button on the steering wheel or other locations, the current from the battery flows through the loop on the horn relay solenoid, solenoid relay attract dynamic contact switch is closed, current will flow to the speaker place. Electromagnet current work inside the horn, so that the diaphragm vibration sound. If the problem is not very serious, the owner can solve their own, Launch X-431 PAD and Launch X431 Diagun III Auto Diagnostic tool can check and fix this problem.

The failure in many of the speakers, especially some design defects speaker mounting location, in the rain, very easy to cause the horn drenched by rain, causing damage to the speaker. When the speaker does not ring, common failure parts have no more than 3 points, namely the horn itself, horn switch contacts and the horn wiring harness, when fault occurs can refer to the following steps to check, of course, you also need some car diagnostic tools.

(1) Sometimes does not ring, press the horn switch, if the speaker sometimes loud, sometimes not loud, mostly horn switch contacts inside the contact is not good, and some are also speaker itself.

(2) hoarseness is due to poor contact plugs, especially the various contacts around the steering wheel, as a result of frequent use, easy to make contacts to wear.

(3) does not ring entirely first checks to see if the fuse is blown, then unplug the speaker plug, use a multimeter to measure when the horn switch here has power.

Use and Maintenance Guide of Car Battery

Among all the car maintenance, the battery maintenance is also very important. While many car owners do not pay enough attention and have not a better knowledge of both the using and the maintenance of the car battery. As a result, they have not formed a good using habit and make the battery life shortened, and even do harm to the other electrical equipment. So, how to check whether the battery can still support working with your car? Maybe you can use a car diagnostic tool for help. A common battery life can be up to 2 or 3 years, if unreasonable used, you may change the battery of your car within 4 months.

Well, how to judge whether the battery need charged, and not make it in a state of loss of electricity? You can determine the working state of the battery by the brightness of the headlights or the strength of the stereo sound. If you wait until the brightness of the light become dark, the power storage would have entered into a state of loss of electricity and unable to start. In order to guarantee the normal work of the battery car owners should better start the engine to recharge it for every half an hour after the using of the battery.

Here are four errors for the using of the battery. All should pay attention:
1. Not charged with the new battery for the first use
Battery charged at the first time is called the first charge, which has a big influence for the battery life of your car. If not charged, and used directly, the capacity if the battery will be not large enough and shorten the battery life. While if charged directly, it will also shorten the battery life. In general, the first charging of the battery is after filling the electrolyte, and use a small current to charge it for about one hour and then you can use it.

2. Ignore the vent of battery
The vent of the new battery cover is usually sealing, when using you must first remove the adhesive paper, otherwise the air vent cannot be ruled out the gas during the chemical reactions, and will lead to an explosion because of the high pressure.

3. Too freely to add distilled water for the battery
Usually after adding the water for the accumulator, you must let the car run for a period of time, and charge the battery through the generator, making the distilled water and electrolyte fully mixed, and then the battery performance will not be affected. Well, after a long time of driving, we suggest you to use a king of tool to make a full checking for your car, including the battery life, such as the Autel MaxiSys Pro MS908P and Launch X431 IV GX4 Master Auto Diagnostic Tool, both are the best choice for you. Conversely, if not running after adding distilled water, distilled water and electrolyte will not be fully mixed, and it can cause the battery self-discharged or damage battery polarity.

4. Battery charge capacity not matched with the engine
If the charge capacity and engine don't match, battery charge quantity is small, the startup resistance increase, battery will put severe electricity, and is sure to shorten the battery life. If charging a small car with large capacity, the active substance will not be fully used, as a result, it will lead to a decline in economy. When loading, the battery is based on the starter battery power, voltage and the load of electrical equipment, so in exchange, it is important to note that matching the engine charge capacity.

Well, for more detailed information about the car maintenance please continue to pay attention to our Auto Diagnostic Tool Online Store and we will upload the latest and most practical knowledge for maintaining your loved car for you.
