A typical car battery is made up of individual cells, with each housing alternating plates of lead and lead coated with lead dioxide submerged in a sulfuric acid solution. This causes a chemical reaction that releases electrons, providing the juice that spins the starter motor, powers the radio and keeps the lights on, among other functions. Sometimes, especially on cheap batteries, the seal around the post allows sulfate in the battery to escape and react with lead in the post, producing white, flaky deposits. … Continue reading Clean and Prevent Battery Corrosion on the Terminal
