VRLA/GEL technology

A gel battery has the sulfuric acid electrolyte mixed with silica material to form an immobilized gel. Although Gel batteries belong to a VRLA category, its construction is similar to VLA (flooded) batteries except for the gelled electrolyte. A Gel battery’s separator material is generally not an Absorbent Glass Mat, but microporous plastic material.

• Recombinant type where water additions are not necessary
• Resistant to extreme service temperature ranges
• Produces less hydrogen
• No electrolyte leakage, as the electrolyte is fixed in the gel. As a result, no insulation faults, no dirty surfaces and no damage to the environment
• Very little self-discharge
• Suitable for medium, partly cyclical loads
• Cells and batteries homologated by different European railways organisations
• Compatible as spare battery for train lighting and Diesel start
• Problem-free, cost-conscious cell replacement
• Fully insulated, maintenance-free fastening technology
