Specifications
Product Description
The 2V Stationary Element TAB 4 TOPZS 353 | 460Ah is a TOPzS tubular cell designed for demanding solar applications and backup systems. Manufactured with tubular positive plates and a translucent polypropylene container, it offers high stability, very low self-discharge, and a service life that can reach up to 15 years. Thanks to its vented lead–acid chemistry and robust construction, this 2 V element is perfect for forming modular banks of 12 V, 24 V, or 48 V in residential, commercial, or industrial installations.
Main Features
- Certified capacities: C10 353 Ah, C20 384 Ah, and C100 460 Ah at 25 °C.
- Low internal resistance (≈0.46 mΩ) and theoretical short-circuit current 4514 A for excellent response.
- Tubular positive plates and microporous separators that maximize cycle life (~1200 cycles, EN/IEC 60896-11).
- Translucent PP container with visible max./min. levels and sealed lid for minimal emission.
- M10 terminals with brass insert and flexible connectors; easy series/parallel assembly.
- Reduced maintenance: electrolyte density 1.24 kg/l, self-discharge ~3 %/month at 20 °C.
Advantages or Benefits
- Long-term reliability: the tubular plate prevents loss of active material and maintains stable capacity.
- Budget optimization: low total cost of ownership compared to monobloc batteries and comparable cycles.
- Visibility and control: translucent container for quick review of electrolyte level.
- Flexibility: allows scaling of 12/24/48 V banks with 6/12/24 elements according to required voltage.
- Safety and service: gas/electrolyte-tight terminals and convenient access for periodic maintenance.
Purpose or Applications
Especially suitable for off-grid solar energy, self-consumption with storage, telecommunications, emergency lighting, control and monitoring, long autonomy UPS, solar pumping, and hybrid microgrids.
