He demonstrates resistance between two copper bars lying down, one on top of the other, with several greases between them. Since corrosion is one of the biggest car battery terminals enemy, I will address some important things. Choisissez un pays ou une région pour afficher le contenu spécifique à votre emplacement géographique. Because it’s not commercially recommended for this application, I strongly recommend using some sort of dielectric grease instead of petroleum jelly.

Applying a small amount of grease to battery terminals prevents corrosion and aids the removal of battery leads. To view the purposes they believe they have legitimate interest for, or to object to this data processing use the vendor list link below. One of the main reasons for this is caused by battery overcharging, making gas escape, passing by terminals, and react with the metal creating oxidation.The main characteristics of a silicone-based grease are that it has very good resistance to hot vapors and can withstand temperatures from -40 °C (-40 °F) all the way to +150 °C (302 °F).

Examples might be garage doors, springs, car door hinges, sliding doors, bolts, hinges, chains, etc. If we want to compare the resistance of different greases, we need to make sure to measure them first. By sealing gaps between contacts corrosion won’t form, and the final result is low resistance, which is good for electrical connections. And it’s more important to grease terminals of a lead-acid car battery types independently from Lithium based types batteries because the Lithium ones will not vent out harsh acid vapours to make terminals corrode.Some of our partners may process your data as a part of their legitimate business interest without asking for consent. The battery will work either way, as long as terminals and clamps are clean out of the corrosion and they are connected and well tight together. Here you can find more about dielectric grease vs conductive grease, and how their application compares to each other on car battery terminals. Wax-based grease is used in applications where parts are moving and rubbing to each other, especially in the bicycle industry to lube chains. Eventually, gas will find a way to escape due to high-pressure buildup inside a battery through terminal seals making terminals corrode.

In our situation, with car battery terminals, we need as little resistance as possible to maintain a solid electrical connection. months and ensure all the cells are filled equally, otherwise a lot of damage may be caused to the battery. It’s recommended for using on hinges, sliding surfaces, spark plugs, chains, lathes, and electrical connections. Prevents the contact resistance from increasing during operation and ensures lower loss than with untreated contacts. There are several types of grease out there you might consider when it comes to greasing terminals to prevent corrosion.

This lubricant is not commonly recommended for protecting terminals, but it can be used in emergency situations. If you do decide to use grease then we would use either copper grease or petroleum jelly (Vaseline) and only apply after connecting the leads to the terminals. When using this product please be careful not to use too much to the point that you would create a barrier between the terminal and the clamp preventing a solid connection.
