Qoltec 53081 gel-accu 12V 120Ah GEL 34,8kg

The Qoltec 53081 Gel Battery is a high-performance, maintenance-free VRLA battery designed for reliable backup power and cyclic applications. With a nominal voltage of 12V and a capacity of 120Ah (C20), it delivers consistent energy for UPS systems, solar installations, marine use, and more. The advanced gel electrolyte technology ensures deep discharge resistance and a long service life of up to 12 years in float service.

Advantages

This gel battery offers exceptional durability and safety. The thixotropic gel electrolyte immobilizes the acid, preventing leaks and allowing operation in any orientation. It withstands deep discharges better than conventional AGM batteries, making it ideal for frequent cycling. The pure lead plates and ABS container maximize lifespan and reliability.

Suitable for

• UPS and backup power systems
• Solar photovoltaic systems
• Marine and boat applications
• Campers, caravans, and motorhomes
• Electric vehicles and forklifts
• Alarm and security systems
• Telecommunications equipment
• Emergency lighting
