Qoltec 12V 150Ah Gel Battery (GEL) - VRLA, Maintenance-Free, 41.8kg

The Qoltec 12V 150Ah Gel Battery is a high-performance, maintenance-free VRLA battery designed for reliable energy storage in demanding applications. Utilizing advanced thixotropic gel electrolyte technology, it offers superior resistance to deep discharge and extended cycle life, making it an ideal power source for backup systems, renewable energy, marine, and mobile applications.

Advantages

Gel technology provides greater durability and stability compared to conventional flooded batteries. The battery is sealed and maintenance-free, eliminating the need for water refilling. With a design life of 10-12 years (EUROBAT Long Life), it ensures long-term reliability. The use of pure (non-recycled) lead and high-quality ABS plastic housing maximizes lifespan and protects internal components.
