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.
Lithium-ion vs. Lead Acid: Performance, Costs, and Durability
Lead-acid batteries rely primarily on lead and sulfuric acid to function and are one of the oldest batteries in existence. At its heart, the battery contains two types of plates: a lead dioxide (PbO2) plate, which serves as the positive plate, and a pure lead (Pb) plate, which acts as the negative plate. With the plates being submerged in an electrolyte solution …
