b.b.battery GBS12/33(12V33AH)

Product details

The Zelus GBS12/33B.B.gel battery redefines power reliability with innovative technology. Its core lies in the silicon-gel solidified electrolyte technology, which combines sulfuric acid with fumed silica to form a stable gel, completely eliminating the risk of acid leakage in traditional lead-acid batteries while enhancing resistance to high temperatures (internal heat is evenly conducted to the casing via the gel) and mechanical shocks.Under the 12V voltage framework, the 33Ah capacity (based on C20 discharge standard) paired with a compact 11.3kg design (dimensions 195x129x168mm) provides continuous power for solar power station inverters, off-grid monitoring equipment, and mobile medical instruments, making it particularly suitable for scenarios with large day-night temperature variations or limited installation space.The battery employs deep-cycle lead-calcium grid technology, increasing cycle life by 50% compared to traditional products, achieving up to 2500 cycles at a daily 50% depth of discharge. Coupled with a precision pressure control valve (opening pressure 18-22kPa), it effectively balances internal gas release and electrolyte retention.In practical applications, users can integrate it into road lighting systems to withstand environments ranging from -20°C to 60°C, or use it as a wind power energy storage unit to maintain stable capacity during frequent charge-discharge cycles (monthly self-discharge loss <2%). The Eurobat-certified 12-year float service life, combined with an IP55 protection rating, ensures maintenance-free operation in high-load scenarios like communication base stations operating 24/7, significantly reducing lifecycle costs. Whether for powering golf carts or serving as backup power for emergency firefighting systems, the GBS12/33B.B.leverages the physical stability of gel technology and the safety of VRLA structure to deliver uninterrupted energy support for critical facilities.

Product Features

GBS delivers long cycle life and prolong life in elevated ambient temperatures
The generated heat can easy flow to the case walls because the whole volume of the cell is filled with gel
The immobilization of the electrolyte in the gel makes acid stratification impossible
Maintenance free(no water topping-up required)
Low self-discharge rate, lower than 2% capacity loss per month
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
