Modelo: 4 TOPZS 500- Sku: TABBATE040
- Vendor: TAB
Specifications
Product Description
The 2V Stationary Element TAB 4 TOPZS 500 | 650Ah is designed for projects that require greater autonomy and sustained current. Its TOPzS tubular design, translucent polypropylene container, and microporous separators provide high resistance to aging and excellent stability in deep cycles, with an estimated operational life of up to 15 years and ~1200 cycles according to EN/IEC 60896-11. It is the ideal basis for building 12 V, 24 V, and 48 V banks in solar, telecom, and critical backup applications.
Main Features
- High capacity: C10 499 Ah, C20 545 Ah, C100 650 Ah.
- Very low internal resistance (≈0.35 mΩ) and theoretical Icc 6005 A for good peak response.
- Tubular positive plates with polyester sleeve and antimony alloy grids <2%.
- Translucent PP container with level markings; M10 terminals with brass insert and flexible connectors.
- Reduced maintenance: self-discharge ~3%/month; electrolyte density 1.24 kg/l.
Advantages or Benefits
- Superior autonomy per cell: fewer series/parallels to reach the target energy.
- Reliability in variable climates: operating range -20 °C to 55 °C (optimal 10–30 °C).
- Competitive cost per kWh compared to lower capacity or monobloc solutions.
- Quick visual verification of the level and easy management of distilled water at wide intervals.
- Simple integration into cabinets or racks, with standard M10 connections.
Purpose or Applications
Designed for off-grid solar self-consumption, microgrids with generator, telecommunications, emergency lighting, industrial control and monitoring, long-duration UPS, and photovoltaic pumping or irrigation systems.
