Valve Regulated Lead Acid (VRLA) Batteries
Maintenance Free Battery Construction. A lead acid battery is made of a number of lead acid cells wired in series in a single container. Lead acid cells have two plates of lead hung in a fluid-like electrolyte solution of sulfuric acid. While in use, the battery generates power by reducing the lead plates, turning them into lead-sulfuric-oxide.
