When you open the hood and see a white, bluish, or green powder on your battery terminals, that’s corrosion. It may not look serious at first, but corrosion creates resistance that restricts the flow of electricity. That means your battery, starter, and alternator all have to work harder just to get the car running. Left unchecked, corrosion can shorten battery life, weaken charging efficiency, and eventually leave you stranded. How Corrosion Develops Battery corrosion occurs because of the natural chemical reactions inside the battery. As the battery charges and discharges, small amounts of acid vapor escape. When that vapor mixes with the surrounding air and metal, it creates the powdery residue you see on the terminals. Heat and humidity are two factors that Tampa drivers are well aware of, which accelerate this process, making batteries in Florida more prone to corrosion than those in cooler climates. Contributing Factors While corrosion ... read more
