Improve Battery Terminal Reliability with Specialty Grease
Battery terminals are often found in automotive and power tool applications where environmental factors can impact electrical reliability. If not protected, salt and dirt can corrode battery terminals; causing either an open connection or a short between positive and negative terminals. Moisture intrusion can have a more immediate effect and cause an instantaneous short circuit as well. Grease protects your battery terminals against moisture and corrosion to prevent electrical failures.
When a contact corrodes, insulative oxides form on the terminal surface which results in increased resistance, signal loss and component failure. The corrosion can also be conductive and builds up to a point where it bridges the distance between two terminals and creates a short circuit.
Even with specially designed housings, there is a risk that dust, dirt, or another form of debris could find its way to the contact pin. When this happens, it can interfere with conductivity and lead to a connection that is not solid. Harsh chemicals can also corrode the metal surface and eat away at the pin’s metal plating.
How Grease Helps
Magnets attract, greases don’t. Grease creates an environmental barrier to keep dirt and debris away from the contact surface. PFPE lubricants are recommended to offer protection in the presence of harsh chemicals.
A lot of moisture can cause an immediate short-circuit whereas a small amount can corrode the connector surface over time. Moisture can corrode the terminal surface over time or even cause an instantaneous short circuit. Moisture can take the form of water, detergents, humidity, or salt spray.
How Grease Helps
Connector grease repels water from the connector surface. Connector grease is hydrophobic, meaning it stays in place rather than being washed away over time. Grease also prevents current leakage in conductive environments, such as water, to ensure consistent connectivity. A connector grease can also create a seal for the connector to prevent water ingress at the housing interface.
Case Study
Commercial vehicles are operated for extensive periods of time under a variety of environmental conditions and depend on reliable components that require shortened and/or infrequent servicing. These vehicles are continuously exposed to road spray, which in the winter contains corrosive salts and chemicals. If a battery or starter terminal were to become corroded, it could cause unwanted downtime as the driver would be unable to start the vehicle or the electronics controls would fail to operate properly.
