SBS-AFT/GFT Series Batteries

The SBS "AFT/GFT" series sealed valve regulated, lead acid (VRLA) rechargeable batteries are maintenance-free. The AFT series combines AGM absorbed electrolyte technology with a catalyst to ensure minimum gassing, reduced float currents, increased life, and safety. The GFT series utilizes a gelled electrolyte, along with a catalyst, and are designed for universal float service and cycling, particularly in areas of poor or unreliable utility power.

The SBS "AFT/GFT" series VRLA batteries are the first monobloc batteries to use a catalyst vent cap design. This reduces the float current by over 50% and the energy required by the battery. It also lowers the heat generated by the battery, and increases the battery's life and reliability.

Gel Technology:

Gel technology has a number of advantages over the equivalent AGM battery range, particularly for telecommunication applications such as:

  • Increased durability and deep cycle ability for heavy demand
  • Full recovery from deep discharge even when battery is not immediately charged
  • Suitable for unstable main power
  • High tolerance to discharge when a full charge has not been achieved
  • Improved cycle life — Limiting design protects the positive plates
  • Superior performance with longer discharges
  • Operates cooler — gel technology provides better thermal transfer


  • Telecommunication
  • UPS
  • Emergency Lighting
  • Stand-by power
  • Switchgear
  • Control systems


  • Compact and modular design lasts 10 years
  • ETSI/19"/23" integration
  • High power volume ratio
  • Central gassing system on all models up to 150AH
  • Excellent cycling ability and low self-discharge rates
  • Front access terminal connections
  • Maintenance-free and low installation costs
  • Operates under extreme conditions
  • Rackable standard component
  • Integral flame arrestor
  • Meets BELLCORE recommendations
  • Compression plate absorbs grid expansion
  • Several rack options available to satisfy voltage and space requirements
  • Four 50AH-150AH AFT/GFTs will fit in a 19" rack
  • Two 200AH AFT/GFTs will fit in a 23" rack
