Do Car Battery Terminals Need Covers?
When doing research on how to care for your car battery, you may have come across the term car battery terminal covers. These are also called car battery terminal protectors and are round covers shaped like a washer that are installed on a car battery’s terminals. In this article, we’ll answer some common questions about battery terminal covers, and explain how they can help protect a car battery.
How to Prevent Corrosion on Battery Terminals
The main function of a car battery terminal cover is to help prevent corrosion. This is a corrosive substance that accumulates on a car battery’s terminals and it will limit the amount of current that can flow from the battery to the engine and from the car’s charging system back to the battery. This not only makes it more difficult to start the engine, but also limits how much the alternator can recharge the battery, which may result in the car’s battery being left in an undercharged state.
How Is Corrosion Caused?
The chemical reactions that take place inside a car battery cause corrosion. Lead acid batteries emit hydrogen and sulfuric acid gas. These gases react with the metal on the outside of a battery and the heat under a car’s hood to create corrosion on the battery terminals which are made from lead alloy. Battery terminal covers help prevent this process as they absorb vapors at the battery terminal’ base, which then prevents them from flowing to the battery terminals.
