b.b.battery GB12/30(12V30AH)

Product details

The Zelus GB12/30B.B.gel battery redefines reliability standards for industrial-grade power supplies. Its core innovation lies in the perfect combination of solid lead coating and silicon-based gel electrolyte. Certified by Eurobat for deep-cycle technology, it maintains a nominal capacity of 28.5Ah even at C10 discharge rate. The compact 11.3kg body incorporates B7 standard terminals compatible with various connection solutions, while its specially designed acid displacement prevention structure ensures stable performance during transport vibrations or high-frequency charge/discharge cycles. Test data shows this model achieves an astonishing durability of 6.8 years of daily cycling under 50% depth of discharge conditions.For scenarios requiring 24/7 uninterrupted operation—whether it's hospital life-support equipment, traffic signal control cabinets, or off-grid solar energy storage systems—its wide temperature range adaptability and annual self-discharge rate below 0.1% ensure continuous power supply for critical equipment during sudden outages. The modular design supports multi-battery parallel expansion, while the intelligent pressure equalization valve effectively prevents overcharging risks, making it the ultimate solution to replace traditional lead-acid batteries.

Product Features

The sulfuric acid is mixed with silica fume, which makes the resulting mass gel-like and immobile
Increased durability and deep cycle ability for heavy demand
High temperature stability, mechanical strength and low acid displacement
Superior performance with deep discharges
Patented safety valve to have accurate pressure operating for long battery life
A small distribution of the special valve opening and closing pressure is important for a good (cycle) life time of the battery
Strengthened rib design to maintain structural integrity
