FIAMM FHT Batteries

Alpine Power Systems' experienced technical support & sales team is here to assist your needs:

FIAMM FHT batteries have been design to withstand harsh environmental conditions. Special grid alloy and superior grids design grant 7 years design life at 95°F. FHT range has front terminal design ideal for installation on cabinet 19” and 23”; it allows easy access for maintenance reducing the installation footprint and maximizing the energy density. FHT uses proven VRLA technology with 99% internal recombination efficiency, is non-spillable and maintenance free therefore requires no topping up of electrolyte during its float-life.
FHT range is compliant with the highest recognised international standard, it is non-hazardous for air / sea / rail / road transportation and it is 100% recyclable. FHT has a self-discharge rate less than 2% per month, guaranteeing long shelf-life. Alpine Power Systems is an approved value-added reseller of FIAMM battery products.

FIAMM FHT Battery Specifications:

  • Superior alloy grid, designed to resist corrosion and provide short recharge time
  • Leak resistant post seal, threaded female M8 terminals with high conductivity and maximum torque resistance
  • One-way safety relief valves allow gas to escape and prevent the ingress of oxygen and flame arrestors prevent sparks or flames entering the battery
  • Flame retardant ABS/PC plastic to IEC 707 and UL94 FV0 (LOI greater than 28%) to guarantee superior thermal stability
  • Installation in any orientation (excluding permanently inverted)

FIAMM FHT Battery Technology:

FIAMM FHT Batteries use AGM (Absorbed Glass Mat) technology. The electrolyte is absorbed in fiberglass seperators with 99% internal gas recombination efficiency. Blocs are grants non-spillable and maintenance free therefore requires no topping up of electrolyte during its whole life. Low self-discharge allows 6 months of shelf life.
