What Does it Mean When You See Corrosion on the Positive Terminal of Your Battery?
Have you ever noticed corrosion on the Positive Terminal of your Battery and wondered what it meant? The substance can be either greenish blue or white, depending on the type of metal of the terminal ends. If the substance is greenish blue, its copper sulfate. The copper from the terminal clamp reacts with the lead in the battery. If the clamps are aluminum, it’ll be whiter in color, creating aluminum sulfate. In either case, you may notice the battery quality start to degrade.
What Causes Corrosion on Battery Terminals?
There are a few things that can cause Corrosion on Battery Terminals:
- Overcharging: When you see corrosion on the Positive Terminal, this means the Battery may be overcharging.
- Vibration: Automotive batteries are designed to withstand vibration, but too much vibration can still cause damage.
- Environmental factors: Batteries are also susceptible to damage from extreme heat or cold.
- Loose connections: If the terminal clamps are loose, they can allow moisture and air to enter and cause corrosion.
