If you have two or more batteries in parallel and one of the batteries is not holding a charge as well as the others, it will cause an imbalance. To equalize batteries in parallel means to bring them all to back up to the same stat. If your car battery is ever flooded, it's important to know how to properly equalize the voltage. Flooded batteries need to be equalized because they have a higher risk of sulfation. Sulfation occurs when lead sulfate builds up. Equalization is a process of charging batteries that helps to restore capacity and improve performance. It is often used on lead-acid batteries, which can suffer from sulfation – a build-up of lead sulfate crystals on the battery pla.
