Specifications
Product Description
The 2V Stationary Element TAB 7 OPZS 490 | 737Ah is a ventilated lead-acid stationary battery with tubular positive plate (OPzS) that stands out for its high capacity, stability in float operation, and reduced maintenance. Designed to operate continuously in demanding environments, it offers safety and reliability in self-consumption systems, telecommunications, and critical backup.
Main Features
- Capacity: C100 ≈ 737 Ah; nominal OPzS capacity (C10) ≈ 490 Ah.
- Nominal voltage: 2 V; tubular technology that maximizes cycles and minimizes corrosion.
- Design life: up to 20 years at 20 °C in float operation.
- Low self-discharge (≈2–3 %/month at 20 °C) for greater availability.
- Translucent SAN container with level markings and cap with ceramic anti-return filter.
- Dimensions and weight (wet): 166 × 206 × 536 mm (L×W×H) approx.; 39 kg.
Advantages or Benefits
- Excellent performance in long discharges (C10–C120) typical of solar systems.
- Low total cost of ownership: lower water consumption and extended maintenance intervals.
- Quick visual inspection of electrolyte level for preventive maintenance.
- High reliability in industrial and mission-critical environments.
- Modularity to scale banks to 12/24/48 V with standardized connections.
Purpose or Applications
Suitable for off-grid or hybrid photovoltaic installations, UPS with high autonomy, telecom base stations, emergency lighting, industrial control, railways, and airports.
