FIAMM FAT Battery series of valve regulated batteries has been designed for high reliability and safety for front terminal telecom installations. The FAT battery series’s front terminal design is ideal for installation in 19” and 23” cabinets. The front terminal design also allows easy access for maintenance, reduces the installation footprint and maximizes the energy density.
FAT 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. The FAT series is compliant with the highest recognized international standards, non-hazardous for air/sea/rail/road transportation and is 100% recyclable. FAT batteries have a self-discharge rate less than 2% per month, guaranteeing long shelf-life.
FIAMM FAT Series uses AGM technology. The electrolyte is absorbed in fiberglass separators with 99% internal gas recombination efficiency. Blocs are non-spillable and maintenance-free. They do not require topping up electrolyte during its life and its low discharge allows 6 months of shelf life.
FIAMM FAT Battery Series Battery Features
- Special lead calcium tin alloy grid, designed to resist corrosion and provide short recharge time
- VRLA AGM technology using low resistance high microporous fiberglass separators
- Leak resistant post seal, threaded female M6/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 plastic to IEC 707 FV0 and UL94 FV0 (LOI greater than 28%)
- Installation in any orientation (excluding permanently inverted)
