Product Details

Sealed lead acid battery, also known as a lead-acid battery, is the oldest type of rechargeable battery and one of the most common energy storage devices. These batteries were invented in 1859 by French physicist Gaston Planté, and they are still used in a variety of applications. Most people are accustomed to using them in vehicles, where they have the ability to provide high currents for cranking power.
