The technology behind our gel battery has the sulfuric acid electrolyte mixed with silica material to form an immobilized gel. VRLA – Gel batteries are recombinant type and do not require water addition, and emit less gas than VRLA type lead-acid batteries. Gel batteries reduce the electrolyte evaporation and spillage that are common to the VRLA battery. Gel batteries are considered to have greater resistance to extreme service temperatures.
Although Gel batteries belong to a VRLA category, its construction is similar to VRLA (flooded) batteries except for the gelled electrolyte. A Gel battery’s separator material is generally not an Absorbent Glass Mat, but microporous plastic material.
Our Solar Gel batteries are maintenance-free batteries with a special gel electrolyte made by mixing acid electrolyte with pyrogenic silica. The design uses pasted plate grids with a large surface area with grids cast from a special Lead-Calcium-Tin-Silver alloy that provides high corrosion resistance, and a special microporous synthetic separator.
