GEL Technology: Stability Without Compromise
This model belongs to the VRLA (Valve Regulated Lead Acid) class, but with a gel electrolyte that significantly improves its performance characteristics. The GDC series batteries utilize AGM-GEL technology, providing high resistance to deep discharge, minimizing the risk of plate degradation, and ensuring safe, sealed, maintenance-free operation. They are ideal for powering IT and telecommunications equipment, data centers, and are a better solution for solar and wind power stations and off-grid energy systems. The GDC batteries comply with IEC60896-21/22 (for stationary installations) and IEC61427-1/2 (for photovoltaic solar systems) standards.
Maximum Energy Density in a Stable Housing
With a capacity of 100 Ah (C10), the battery provides long-lasting power for critical systems. Its maximum discharge current reaches 800 A (for 5 seconds), ensuring reliable system startups even under sudden peak loads. The maximum charging current is 20 A, guaranteeing efficient recharging without overheating or shortening the battery’s lifespan.
Despite its 30 kg weight (±5% deviation), the battery retains compactness for its class, with dimensions of 215 × 328 × 172 mm, allowing it to fit in standard cabinets and enclosures. The package includes M8 bolts for connections.
Lifespan of up to 15 Years: Durability with Consideration of Cycling
In buffered operation mode, the battery can last up to 10 years, but it is also capable of withstanding a moderate number of charge/discharge cycles. It is important to consider that the depth of discharge (DOD) directly impacts the battery's lifespan:
- At 30% DOD: up to 1,200 cycles
- At 50% DOD: up to 600 cycles
- At 100% DOD: up to 300 cycles
This shows that GEL technology is effective for buffered use, but it is not intended for frequent deep discharges. For this reason, the battery is not recommended for use in off-grid or mobile systems, where cycling is constant.
Temperature Parameters: Adaptive Performance
The recommended temperature range for operation is +15°C to +25°C, as it provides the highest stability and longevity for the battery. However, it remains functional even under more extreme conditions. The battery's capacity changes depending on the temperature:
- 102% at +40°C
- 85% at 0°C
- 65% at -15°C
This performance profile makes the battery versatile for use in indoor environments, technical rooms, and telecommunications systems.
Adhering to Guidelines for Long-Term Operation
Despite its high potential, it is crucial to adhere to the recommended operating conditions:
- Do not use the battery outside the recommended mode.
- Always fully recharge the battery after discharge.
- Calculate the overall system capacity according to the battery class and load specifications.
It is also important to consider the self-discharge rate, which is only 3% per month at 20°C, ensuring long service life without loss of functionality.
