How to lubricate the battery terminals from oxidation. How to lubricate the battery terminals to not oxidized. Oil-based

the main / KPP

Each driver is obliged to clearly know than to lubricate the battery terminals, so as not to oxidize, for it makes it possible to avoid problems. Irresponsible attitude in this issue will lead to the fact that for starting from the place, the car will need to push, and the term of use rechargeable battery will decrease. As for his recovery, this is a fairly costly thing, and the purchase of new and suppressed.

What kind of tool still use? The question is very relevant among motorists. There are those who try to acquire new funds, but are those who trust only proven methods.

As for modern funds, the following are used:

Molykote HSC Plus. It has high electrical conductivity. Works at temperatures from -30 to + 1,100 degrees Celsius.
Spray-lubricant German production. Well protects terminals from oxidation. Promotes a stable voltage supply.
"CIATIM". It has good performance indicators. It is famous for acceptable cost.

Causes of oxidation

Having understood with the types of lubricants, it should be found out why the battery terminals are oxidized. In fact, there are a number of reasons, here are the main of them:

Bad contact between the end of the wire and the battery itself. During operation, a gap appeared in which there are pairs from electrolyte. Damage is only to sealed.
Terminal coverage scratched or erased. Replacement is needed.
The withdrawal of the battery is not sealed. The electrolyte seeps and the surface of the contact node is discharged.
The generator is rechargeable. In this case, it is worth going to those skilled in the art.

If the battery terminals are constantly oxidized, what to do? Above it was said, how to behave in the case of the reasons given. But how to be when oxidation has become so strong that the car stopped starting. In this case, you need to clean the terminals. For this, sandpaper takes and carefully erased. It is extremely careful to act in order not to damage the insulating shell. Perform work in gloves. For better contact, use one of the lubricants, about which it was above.

When a plus terminal is oxidized, this may occur for the following reasons:

In any place, the tightness of the battery is broken. It is urgent to intervene in the situation, because over time the acid will be able to pass the case without any special problems.
The battery was systematically recharged, which led to overheating electrolyte and as a result, he began to evaporate too much. In this situation, nothing remains except to go on the automotive market or in a car shop to buy a new device.

What to lubricate? At the beginning of the article, the most popular lubricants of both old and new sample were given. Add only lubricant for Liqui Moly battery terminals. Among her features should be noted reliable protection Contacts from corrosion. The motor will work in any weather conditions. The most important thing is that the use of the battery is increased almost two and a half times. Such lubrication prevents current leakage. Before applying it, it should be highly cleaned the necessary place. Again, use the knife or emery paper, as previously written.

As you know, the battery is one of the main elements necessary for the normal operation of the car. Failure or incorrect operation of the battery will somehow affect the functioning vehicle generally. In this article we will talk about the prevention of AKB, in particular, about solving the problem of oxidized contacts.

Causes of the coating of the battery terminals

Before you begin to solve the problem, you need to find out, as a result of which it appeared. The causes of oxidation are several:

Poor battery condition, i.e. Electrolyte leakage. Often, the leakage of the electrolyte occurs when the battery is recharged, and the reason is the incorrect operation of the generator or chain. Also, the electrolyte may be incorrect density or it follows as a result of the closure of the cells of the AKB.
The reason may be wounded in the damage to the battery case. In practice, the leakage of electrolyte comes from the cracks that appeared on the body. It should also be noted that when the electrolyte gets into the battery terminal, the oxidation will be impossible if it comes out through the crack near the contact of the AKB. In the same places, the cracks appear due to the clips vibrating (terminals) in the housing.
Another reason can be a malfunction in the vehicle wiring. And faults, in turn, arise as a result of a bad connection between the clamp and the battery contact. It is often encountered and the problem of a bad connection of the chain in the relay or contact groups.
When the holes of the cans of the battery are clogged with garbage, the level of electrolyte pressure is increased in the bank itself. Crashing banks are usually found on old batteries, but, nevertheless, it causes cracks and cracks through which the electrolyte will go out.
In addition, oxidation may indicate that the battery has already worked out its resource of operation and soon may simply fail.

One way or another, but this problem affects not only the work of the car as a whole, but also on human health. Therefore, it is necessary to solve it immediately.

Preliminary processing

To proceed with the process of lubricating clamps, the acb processing from already existing oxides and dirt should be processed. To remove the dirt, fit and simple distilled water, but it will not be able to help from oxides. In practice, many domestic motorists use a solution of soda. It allows you to almost instantly remove oxidation, but after it the clamps will need to be treated with water. Some motorists claim that for pre-treatment it is quite possible to use the cola, and the result allegedly much effective soda.

If you are a fan of physical methods, it can use emery paper. But it is necessary to take the smallest sandpaper, because scratches can remain from its operation. And in the future, this will cause even faster oxidation of the AKB. However, sandpaper oxidation may not be completely removed - small particles will remain. When the terminals are processed, they must be wiped with a dry cloth for further lubrication.

Review of funds

Below, consider the tools intended for processing battery clamps. The list of funds is far from complete, on modern automotive market You can find dozens of species of various substances intended for these purposes. But we will look at the most popular of them, tested by time.

"Dedovsky" means

The first and most "ancient" method of lubrication of battery clamps is solidol. This "Dedovsky way" has been successful in the 50s of the last century, but over time, there is no popularity with no. The chemical composition of solidol contains a component - a stabilizer of a structure - which, as a rule, is ordinary water. However, its popularity decreased, since the operation of solidol was irrelevant for rubbing nodes, where the temperature rose to 100 degrees. In the case of the battery, this lubricant will be a good option for processing clamps, but the fatty solidol will be best acquired.
Petrolatum. It may seem strange, but the use of Vaseline as a lubricant of battery terminals is a common thing that has been popular about 10-20 years ago. Of course, traditional pharmacy vaseline is not suitable for these purposes. Especially for the processing of clips of car VAZ, technical Vaseline WPTV-1 was created. It is a conservation lubricant with good technical characteristics and protective functions. Technical Vaseline is an oil oil in a compartment with paraffin and ceresine, which makes it possible to ensure the proper level of moisture resistance and low-temperature characteristics.
Even a small lubrication layer is less than a millimeter - it allows to prevent corrosion of metal elements in humidity conditions over several months in a row. Technical Vaseline has high level Water resistance and conservation, as well as adhesive characteristics.
Litol. This lubricant was also no time popular, but with the advent of imported lubricants, its popularity was sent to the background. However, experienced motorists Constantly advise novice to use a litol as a lubricant in friction nodes. Litol is an antifriction multipurpose waterproof material, which began to be produced in the USSR. Since it is waterproof, its use is quite justified in the terminals of the AKB.

Liqui Moly.

Liqui Moly. It is a lubricant designed specifically for terminals battery. It makes it possible to prevent the emergence of corrosion, contributing to the increase in the level of stabiliary of the AKB as a whole. According to the manufacturer, the use of Liqui Moly allows you to reduce battery voltage loss, thereby increasing its service resource. This tool is modern and proven domestic motorists, so in its characteristics you can not doubt. The only drawback is his high price Compared to Solidol.

In essence, Liqui Moly is the same vaseline, only synthetic and acid-resistant. It has red color. According to the manufacturer, it contributes to preventing acid or condensate on force electrocontacts. In addition, Liqui Moly reduces the voltage leak on the battery surface.

Specifications:

good properties for electronics;
full compatibility with plastic elements of the battery;
anti-corrosion characteristics;
it helps to reduce the level of contact resistance.

Presto.

Actually, much different from Liqui Moly. Also designed to protect the contacts of the battery from the oxide and contributes to the prevention of corrosion. Presto has the property of preventing the power loss of the battery, and its operating range ranges from -30 to +130 degrees Celsius. The color of the substance is blue. Protective fooling rings

To prevent this problem, you can use one of the two most valid options:

Felt, spent in motor oil. This method is the same ancient as Solidol. A piece of felt is lubricated in motor fluid And puts on with the Accord terminal or its contact. Contact is delayed in the future, the battery is used in this form.
Felt washers. Such washers can be purchased in stores where they are directly batteries. As in the previous case, felt washers dressed on terminals, after which the contacts need to be tightened as much as possible.

Exploitation car batteries conjugate with elevated loads due to significant temperature fluctuations in motor compartment, the effects of dirt, dust and moisture. In addition, sometimes there are situations associated with the overheating of the battery and reset overpressure through the valves with the separation of acid vapor.

All this inevitably leads to a gradual deterioration of contact and. To reduce the negative oxidizing effect of various reagents on the contact pads of the battery, lubricants are used that flashes from above reliably collected locations of the compound.

Do you always need to protect terminals from oxidation

In a technically serviceable car with good batterywhich has no cracks on the housing, including those caused by excessive effort when clarifying the terminals, their oxidation occurs very slowly. If the car is put on the parking lot in a dry and ventilated place, the risk of deterioration of contact is even more decreasing.

Nevertheless, in whatever ideal conditions, the car was not operated, it inevitably occurs the oxidation and burning of contacts, which is the most strongest on the terminals of the AKB, where at the time of launching the starter pass huge currents in hundreds of amps. In addition, water pairs and oxygen are always present in the air, which slowly, but confidently lead to corrosion of metals.

In the presence of a whitelized fly, which most often occurs on the plus terminal of the battery, the use of protective lubrication makes it possible to continue the operation of the car if it is not possible to replace the battery. To do this, it is necessary to clean the contacts, put the felt gaskets impregnated with lubricant between the battery case and the terminals, connect them to the conductor, tighten and lubricate the contact compound on top. A minus terminal also needs to protect against governments and oxidation, due to the constant finding in the hot rotten space with road dust and moisture.

The use of lubricant for terminals will help extend the operation of the battery and improve the overall reliability of the car. The use of special compositions in order to protect the battery terminals seems to be a reasonable prophylactic measure capable of reduce the number of unpleasant surprises that may appear at the most inopportune moment.

How to lubricate the terminals from oxidation

The main purpose of the lubricant of electrical compounds is the prevention of dirt and oxygen in the place of contact, which contributes to not oxidized.

It is desirable that the protective covering does not collect excess dirt and performed its protective functions as long as possible. There are many different options Protecting the terminals of the battery, each of which has certain advantages and disadvantages. The main condition should be the absence of corrosive effect on contacts, insulation of the wires and the surrounding rubber parts, high temperature and acid resistance.

These compositions are usually based on mineral oil with the addition of graphite powder. They have good water repellent properties and perfectly protect against corrosion. An ordinary graphite lubrication makes temperatures from -20 to +70 degrees, but there are more expensive high-temperature options. In connection with the possible overheating of the boost space in hot weather it is better to apply them.

Graphite is well conducted by electric current, so its penetration inside the contact connection does not deteriorate so much electrical contact, as lubricant with dielectric properties.

This type of lubricant is withstanding a large temperature, has anticorrosive properties, it is well held on the surface, but does not conduct electricity. They are made on an oil basis with the addition of special additives and dyes, which make it easier to apply a protective coating.

it a good option protection against oxidation when using special protection compositions, such as Liquimoly, Addinol, Molykote, Gunk and others.

These lubricants are durable, have a high viscosity, electricity is perfectly carried out, withstand high temperatures (from -35 to several hundred degrees), are perfectly protected from corrosion, moisture, progarov.

Special copper lubricants are available for electrical contacts in the form of sprays, for example, Berner, as well as copper strokes for high-loaded moving connections. They have different properties, but both options can be used to protect AKB contacts.

These lubricants withstand temperatures from -30 to +130 degrees, have an average viscosity, well hold onto the surface and provide high tightness of electrocontacts.

A good form on a wax basis is Presto Batterie POL Schutz, which is able to withstand temperatures from -30 to +130 degrees and is easily applied using an aerosol sprayer.

This is an excellent version of the protection of contact compounds with good resistance to the effects of hot vapors, disinfecting solutions. Silicone grease sticks perfectly to surfaces, neutral and can work with a wide range of temperatures from -40 to +150 degrees. Produced by many verified manufacturers, including Shell, Fuchs, Molykote, Roco and others.

Disadvantage silicone lubricants It is the need to regularly update the protective coating.

These include such common compositions like solidol, lithol, cyatimm 201, Vaseline. These compounds are used to protect against wear of rubbing surfaces, have a high fluidity that increases with increasing temperature in the engine compartment, so they are not very suitable for the protection of electrical contacts. In case of serious problems with the oxidation of contacts, they can be used to protect terminals, but it is better to do it only in winter time years, when these lubricants are fluid.

Exist special compositions based mineral oilscontaining special additives that improve their temperature durability and therefore make it possible to protect them to protect terminals. These include:

Liqui Moly Kupfer Spray - Oil lubricant with the addition of copper powder intended for brake shoes. It can also be used as a protective coating for the outer surface of the contacts;
Liqui Moly Batterie Pol Fett is a special protective lubricant with a red dye. Permissible temperatures - from -40 to +60 degrees.
VMPAUTO MC1710 - Mix different oils, as well as silicone with a blue dye. It can be used at temperatures from -10 to +80 degrees.

These lubricants are designed to form on the rubbing parts of the dry coating. They are not very well suited to protect electrocontacts due to their high penetrating ability, which can worsen electrical contact.

Violation of contact in the Accord terminals, where very strong currents flow, is not only an undesirable, but also dangerous phenomenon. In this regard, it is not recommended to use Teflon lubricants on contact compounds.

How to lubric the terminals

Protective properties of lubricant only with good and good electrical contacts in protected connections. If it is not, then the application of lubricant will not restore it.

When applying lubrication on the terminals, you need to understand that between contact surfaces It is not necessary to apply it in order not to worsen the conductivity. Before connecting terminals with conductors, it is necessary to achieve the perfect cleanliness of the metal on the contacts, up to the processing of coarse cloth or shallow sandpaper, wipe their alcohol, and only then twist. After that, you need to apply a protective composition for the collected and tightened with the desired force. If the lubricant is thick, then it can be anointed to the contacts of the rubber glove, and when using the spray, process the protected surfaces from the canopy.

Application conductive copper lubricant Inside contact sites can be justified in case of their poor quality, the presence of large irregularities that reduce the total contact area.

Attention! If a dielectric lubricant falls into the space between the contacts of the battery with the wiring of the car, this will deteriorate the conductivity of the contact and with a large current will lead to the appearance of exercise, even greater conductivity deterioration, as well as the risk of melting the insulation of wires and even a fire due to high temperatures.

Precautions

As a rule, all technical lubricants in the same degree are toxic for the human body. Therefore, work on their application should be carried out in gloves. If you get on the skin of technical lubricants, it is necessary to immediately wash off with warm water with soap.

Important! When applying the protective lubricant, it is necessary to ensure that it does not fall on rubber tubes, gaskets and others that do not need such a surface treatment. It is necessary in order to avoid the destructive impact of those contained in lubricants Components on these materials.

The car battery is enough "thin" and a very capricious thing, if it is wrong to use it, then you can deal with a matter of days. Of course, now the technology go ahead, all the more advanced types are produced, such as calcium options, it is worth it. But the same braceling terminals from above remain unchanged, but they are in a fairly aggressive environment - it is the heat (in summer), moisture (autumn, spring), snow and cold (winter). They can also be covered by dirt oxides and other "charms". Therefore, in order to protect them, it is desirable to smear protective compositions. But what? And how to do it right, let's understand ...

Actually, the cracks began to lubricate for a long time ago and, and therefore there were no special lubricants before, everything was done almost with infirred means. But really, why do it? Why lubricate the accumulator contacts?

Why lubricate?

There are several reasons here, but still initially this is the reason, so:

In order to improve the electrical contact of the chain, there are lubricants that really improve the throughput properties of electricity
Perhaps the most important reason is protective properties. The thing is that lead (terminals are also made of it) is used to oxidize. Especially under the influence of the environment. Another minus, on the old cars of the terminals were copper, and the contacts, respectively, oxidation appeared from lead, respectively, different metals over time. Well, even if you take old acb, served (made in the surmished technology), then they often outlived electrolyte from cans, and quite violently. Evaporation went along with a part of sulfuric acid, she could also get to contact. Here you - again oxidation.

By the way, many auto electricians recommend processing such protective compositions and body weight, it can also oxidize with time. In fact, so that nothing oxidized these contacts and lubricated the terminals, if it is not 100% protection, then at least the decay products did not appear quite a long time.

So what are scary oxides?

Yes, it is clear how - worsen the wiring of electricity from the battery to the starter. In my practice there was such when the terminals were covered with completely oxidation processes and they really interfered with the engine. Ranally increased resistance, and even completely new battery could not run the motor, because very large currents are needed for startup.

Also these products are scary, and this is even very bad for working battery, if you do not touch the battery for a long time, it will sit in zero.

In general, in any case, you need to remove the oxides and protect the terminals and the accumulator contacts.

Lubrication as a means?

Actually, if the terminals and contacts were already oxidized, then the lubricant is useless here, it will not remove them. You need to start cleaning all the elements of pollution, and the "Daughter", many say "to shine", and this is the terminal and the contact itself and only after that you need to lubricate! And only then the protection will work, it will really not be covered by a raid. Purpose One thing - displace water and create protective properties on the surface.

Another important question is what to take, in the tube (that is, in the form of a thick lubricant) or in the form of a spray. The question here is not unequivocal, the auto electricians recommend that the lubricant is recommended, that is, you need to squeeze "as a paste" and physically smear contacts, work can be done in gloves. Aerosols also have a place to be, however, when spraying, it can fall on the surface of the battery, which is also not very good, so after spraying on the desired surface, we clean all other places.

Old processing method

What did you proceed? Basically Lithol (Nigrol). This is a technical lubricant designed to process a set of nodes.

The second most prevalence is a technical and even "ordinary" vaseline. Its consistency also helped to form a protective layer.

However, these two treatments cannot be called highly efficient, yet lithol and vaseline, poorly carry out energy and do not contribute maximum efficiency. Therefore, if they fell between contact and terminal, the effectiveness fell at times. Another minus can be called that the film that was formed from above was not so effective, and washed off (contaminated) very quickly.

New types of lubricants

Special compositions have been developed for terminals that can actually improve not only protective properties, but also carrying out electricity. Actually a lot of compositions, each self-respecting company will be found on such.

They are specifically tinted with blue or red colors so that the treated surface can be distinguished.

Liqui Moly. Technical vaseline with improved characteristics, paints terminals in red.

VMpauto MC1710. Collect terminals in blue color. We look a little video

Molykote HSC Plus. This composition improves electrical conductivity, and also withstands low and extremely high temperatures (up to + 1000 degrees).
Cyatim. Russian manufacturerThe cost is not high, but approached Litol.

But any lubricant should be correctly applied differently, you simply apply more harm than good.

How to apply?

Actually, everything is simple here, but you need to follow several items:

If there are oxidation products, then you need to remove them
Next, we clean the terminals for clean to remove the "film" of oxidation
We dress the terminal for the contact of the battery and tightly tighten the key
We process the upper and side parts, we need to ensure that the water does not penetrate the connection site. Remember to process separately the terminal and contact - no need, and then connect them!

Actually, all, I think the information was useful for you, proceed correctly and your battery will work for a very long time. That's all, sincerely your autobalkher.

A friend who returned from the maintenance, indignantly waving the resulting account: for the lubrication of the terminals of the battery with it, almost as full tank On gas station! Creek Soul: Why are they generally lubricated?

I remember, in the "Zhigulevskaya" era of the Akb terminal and the tips of the connecting wires are abundantly covered with lithol and other solidols - but is it necessary to do this today? Let's think.

Why lubricate them?

Not at all in order to improve electrical contact in the chain. And Litol, and modern funds presented in photographs are dielectrics, and therefore can only worsen conduction. Their task is to protect contacts from external influence. The fact is that non-ferrous metals (in our case - lead alloy) have a bad habit of oxidation under the action of the environment. Humidity is made in the place of installation of the battery, the malfunction of its ventilation system, and on the ancient machines - and the leakage of the battery. It is clear that all these reasons need to be eliminated, and not only to deal with their consequence, but does not interfere with one another.

What is the scary oxide films?

How does the lubricant fight with oxides?

In no way! If the terminal was already oxidized, then lubricants are useless. In this case, you need to disconnect the battery from the network, clean the terminals and tips to the brilliance, then re-connect the battery - and only then use lubricants. They prevent the appearance of oxides, but are not able to eliminate them.

Spray or smear?

All battery manufacturers, pointing to the need to lubricate the terminals, say precisely on consistant oil-like preparations. They hold longer on the treated surface, creating more reliable insulation in comparison with sprays. Although the appointment of all drugs is one to force water and create a protective surface.

What are bad old tools like lithol?

They are noticeably inferior to modern in efficiency: they are easily washed off with shampoos, they have a loose, loose structure, there are no additives and additives. Yes, and the dye is not provided. Trifle, but with colored lubricant to work more conveniently. However, many instructions for domestic batteries do not change for decades, and therefore still recommended lubricants like the same lithol-24.

Outside or inside?

In the instructions of foreign firms, an erroneous translation is often found when it is recommended to lubricate the terminal before putting on the tip of the wire. In fact, the connection "Terminal - Tip" must have maximum contact "Metal to Metal". Therefore, the applix of the dielectric inside nothing but harm will not bring.

Is it possible to use mechanical cleaning of terminals - for example, emery paper?

Yes. For example, the company "Act" directly indicates the instructions: To remove an oxide film from the battery conclusions, use sandpaper. And in Soviet times for mechanical cleaning of terminals and tips, special metal rams were used - internal and external. Of course, the sandpaper should be shallow, because it is impossible to change the connecting dimensions.

Is the terminal of modern batteries too oxidize?

The current material processing methods have rolled us from shells and other inhomogeneities. Some battery manufacturers even use bushings manufactured by external firms. Podcast space modern cars It is also better protected from exposure to external factors. But the contacts are still oxidized - even slower than 30-50 years ago.

(1) Spray cleaners Electrical contacts are Astrohim, Hi-Gear, Svitol, Permatex and other brands. They are usually made on an oil basis - for example, on a purified vaseline oil. Purifiers oust water and form a protective insulating film on the surface. They are suitable for surface processing of the battery terminals, but are inferior to greases in the strength of the coating.
(2) Consystem Lubricants To protect the battery terminals, supplied, for example, Liqui Moly and Gunk firms. Unlike aerosols, these lubricants create a "long-playing" insulating coating. Their base is also oil. Resistant to shampoos. The bright color of modern lubricants facilitates control over the preparation.

So lubricate or not? Our opinion
The likelihood that the unwashed terminal gives some problems today is small. Materials are high-quality, under the hood relatively clean, the case of the battery is sealed. Yes, and the money is a pity. But still we believe that lubricant is useful. If only because it is one of the additional bricks creating
