- Vendor: TAB
Specifications
Product Description
The 12V Stationary Battery TAB 4 TOPZS 500 | 650Ah is a 12 V bank composed of six 2 V TOPzS elements with tubular positive plates. It offers high capacity, excellent stability in deep discharge, and very low maintenance, making it a professional solution for solar self-consumption, microgrids, and continuous backup systems. Its translucent polypropylene container allows for quick visual inspection of the electrolyte level, while the M10 terminals facilitate safe and scalable connections.
Main Features
- Configuration: 6× 2 V TAB 4 TOPzS 500 elements (12 V bank).
- Certified capacities: C10 499 Ah · C20 545 Ah · C100 650 Ah (25 °C).
- Reference energy: ≈7.80 kWh at C100 (12 V × 650 Ah; usable depends on DoD and temperature).
- Tubular plates, microporous separators, and translucent PP container per cell.
- Low self-discharge (~3 %/month at 20 °C) and typical lifespan ~1200 cycles / up to 15 years.
- M10 terminals with brass insert and flexible connectors for series/parallel assembly.
Advantages or Benefits
- Great autonomy per battery: fewer parallels needed to reach system capacity.
- Competitive total cost of ownership compared to conventional lead-acid monoblocs.
- Simple inspection and maintenance thanks to the translucent container and service caps.
- Solid response to demand peaks due to its low internal resistance per cell.
- Compatibility with DC protections, battery monitors, and standard ventilation systems.
Purpose or Applications
Suitable for off-grid solar energy, self-consumption with storage, telecommunications, emergency lighting, industrial control and monitoring, long autonomy UPS, marine, and caravans with continuous consumption.
