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

Applications:

Telecommunication
UPS
Emergency Lighting
Stand-by power
Switchgear
Control systems
