A VRLA battery is short for “valve-regulated lead-acid battery.”
The Valve Regulated Lead Acid (VRLA) Battery is a type of rechargeable battery.
Battery terminals are the electrical contacts used to connect a battery to a charger or a load (a device that needs energy).
Lead-acid batteries continue to provide base load to the battery economy because of cost effectiveness and long life.
Lead-acid batteries have been around since 1859 when Gaston Planté invented them.
