Should you use dielectric grease on battery terminals? Dielectric grease does not conduct electricity. Proper application is important! Do NOT get grease between the terminals! This will inhibit good connection and shorten battery life.
Is it OK to put grease on battery terminals?
In the Cleaning a Car Battery section, it says to prevent corrosion, you should put grease on the clean terminal post before you reattach the cable. It will not interfere with the electrical connection, but will help prevent future corrosion by displacing the air in the surrounding space.
What is the best thing to put on battery terminals?
Step 5: Rub petroleum jelly onto the terminals and reattach the cables. Once the terminals are dry, dab a bit of petroleum jelly onto them. This will lubricate them, help prevent further corrosion, and help strengthen the connection. Reattach the positive and negative cables, and you're all set!
Can you put dielectric grease on connectors?
Dielectric grease ensures longevity of your connection points and creates a proper seal. Dielectric grease helps create extra insulation for electrical connectors, prevents arcing and is ideal for any electrical connections with rubber gaskets.
When should you not use dielectric grease?
See all 4 photos Since it's a low-viscosity grease, many experts advise not to use dielectric grease in high-temperature components that will see in excess of 500 degrees Fahrenheit.

What is the best grease for electrical connections?
Dielectric grease is often used to seal the connection between spark plugs and spark plug wires. Dielectric grease, or tune-up grease, is a silicone-based grease that repels moisture and protects electrical connections against corrosion.
Where should I put dielectric grease?
What should I put on my battery terminals to prevent corrosion?
An inexpensive way to keep corrosion from building up on your car's battery terminals is to apply a tablespoon of petroleum jelly to both the positive and negative posts. Use a wrench to remove the battery cables from the posts, and rub the petroleum jelly onto each terminal.
Can dielectric grease cause a short?
However, unless a dielectric lubricant is applied, the connector will continue to wear and will eventually oxidize and corrode. Dielectric grease has two primary benefits: Dielectric properties become especially important in multi-pin connectors, eliminating the possibility of a short between pins.
How do you use dielectric grease on battery terminals?
Is Vaseline a dielectric grease?
The difference between Dielectric Grease and Vaseline is that the dielectric grease is mainly used for sealing and protecting the electrical circuits and components while Vaseline is majorly used for coating the equipment parts to prevent them from corroding.
What causes buildup on battery terminals?
What Causes Battery Corrosion? The most common cause of battery corrosion is when hydrogen gas released from battery acid causes a chemical reaction with the metal terminals. Corrosion typically looks like a flaky layer of white or green discoloration that sits on your battery terminals.
Can you put dielectric grease on relays?
The copper grease is OK but messy and should not be necessary. Die electric grease is for use on the secondary ignition connections. It's main purpose is to prevent arcing of high voltage connections. Anywhere else is not recommended.
Do I need to use dielectric grease?
Most commonly applied on spark plug boots, lightbulbs, and battery terminals, dielectric grease is, in theory, a protectant like car wax. It's not required, but it could help extend and maintain the life and quality of your vehicle and its parts.
How do you grease battery terminals?
Is Lithium grease the same as dielectric grease?
– The lubricating oil within the lithium-based grease is held tightly against a metal surface which helps it do a better job than oil in lubricating and protecting against rust. Dielectric grease, on the other hand, is a waterproof grease that repels moisture out of a connection.
Does dielectric grease go bad?
It can stay for years. Some people tend to think that dielectric grease products automatically go bad two or three years after they have been opened. However, this is not correct. If you have a dielectric product that is still thick and pasty, you should not shy away from using it.
What grease improves conductivity?
Silicone dielectric grease will prolong connection life as well as, and have just as good conduction performance, as a properly selected metallic powder grease (conductive grease).
Can you put wd40 on battery terminals?
WD-40 Specialist Fast Drying Contact Cleaner can act as a protective layer, applied on the poles and terminals of the car battery and successfully eliminate oil, deposits of grease and mud.
Is petroleum jelly electrically conductive?
In fact, Vaseline is an electrical conductor. You prefer other forms of grease because of that. It's purpose is to fill any air gaps that would promote ozone build up in the joint.
How do I keep my car battery from corroding?
Apply battery-terminal grease to the terminals to help prevent corrosion. It's available at any auto parts store and usually comes in a little ketchup-like packet. Another great option is AMSOIL Heavy-Duty Metal Protector. It creates a protective coating on terminals that wards off corrosion.
Where do you put dielectric grease on a spark plug?
How do you keep electrical connections from corroding?
Using a high quality sealed electrical connector can protect against moisture and contaminant causing corrosion. The simplest way to prevent corrosion damage is to use heat shrink terminals and electrical wire connectors in place of non-insulated, vinyl or nylon insulated options.
Where should you not use dielectric grease?
Dielectric grease is silicone-based grease that repels moisture and prevents electrical connections from corroding. The grease is a non-conductor of electricity. You are therefore advised not to apply it on mating surfaces of electrical connection.
What can replace dielectric grease?
Silicone-based Grease Silicone grease or silicone based grease has been considered to be one of the excellent options for the best dielectric grease alternatives. The best possible electrical insulation offered by the silicone based grease can prove to be one of the excellent options.
Is wd40 a dielectric?
With a dielectric strength of 35KV, WD-40 can restore electrical connections, protect components from moisture and even rescue flooded equipment.
How do you get corrosion off battery terminals?
Mix a very small amount of water with some of the baking soda in a lid or small dish. Then, use the toothbrush to apply the paste to the terminals and clamps. Scrub thoroughly until the white substance disappears. If necessary, you can make use of steel wool to help remove the corrosion.
What is the white stuff on battery terminals?
The white substance which you see around battery terminals is either lead sulfate or anhydrous copper sulfate. Anhydrous copper sulfate changes to blue color when exposed to moisture.
Does corrosion drain car battery?
Without proper attention, your car's battery can corrode, possibly leaving you without a working car. Corrosion can drain power out of a battery and shorten its life. Battery corrosion is typically apparent at the terminals, a problem that can be resolved by careful cleaning.
