A valve regulated lead acid (VRLA) battery is also known as sealed lead–acid (SLA) battery is a type of lead-acid battery. In this type of battery, the electrolyte that does not flood the battery but it''s rather absorbed in a plate separator or silicon is added to form a gel.
Lead-acid batteries may be classified as either flooded or valve-regulated lead-acid (VRLA) depending on the state of the electrolyte. In a flooded lead-acid battery, the electrolyte exists in a reservoir as a free liquid. Accidental contact between electrodes is prevented by coating the negative electrode with a thin separator [195].
