TECHNOLOGIES
Fiamm technologies have been developed and optimized during years to meet different market needs. AGM-technology based products are manteinance free, as well as GEL-technology that enhances product behaviour even in critical conditions. Flooded products ensure high reliability thanks to a low maintenance and specific attitude to different discharge rates.
AGM Technology: (Absorbed Glass Mat) batteries offer improved performance with faster charging, longer life and safer operation. These Batteries are constructed with an absorbent glass-mat separator between the negative and positive plates. Special safety valves are fitted to minimize electrolyte dry-out ovet the life of the battery.
Gel Technology: Gel Batteries use a jellified electrolytrev between psitive and negative plates to minimise dry out of the cell. Batteries with a GEL internal structure are very versatile. They offer excellent long life and perform well in a wide range of temperature conditions.
Flooded Technology: Batteries with a flooded electrolyte are extremely robust and havethe longest life of lead acid accumulators. These cells are manufactured with clear containers showing electrolyte levels to allow periodic topping up.

FG
General Purpose AGM Battery
The FG battery range has been designed to cover a wide range of applications. The footprint of batteries is also ideal for critical installations. Connection is simple on smaller model sizes thanks to the easy ‘fast-on’ terminals. Fiamm's FG batteries are designed with unsurpassed proven reliability and are compliant with the highest recognised international standards and is designed to meet medium to long discharge rates and with a design life of 5 years. The FG is designed around AGM VRLA technology, fully recyclable, non- spillable and maintenance-free. and is available in 6V or 12V versions with a capacity range from 1.2Ah to 42Ah. The FG range is non-hazardous for air/sea/rail/ road transportation and is 100% recyclable. Batteries can be installed in upright and horizontal planes.
Fiamm Batteries, with a very long life spam classification, are designed for more than 12 years operation in accordance with the Eurobat Guide.
Flame Retardant Casing: Most Fiamm batteries are made with flame retardant plastic to provide an extra level of safety and customer assurance. This material o ffers maximum strenght over life.
Fiamm Lead Acid batteries are 99% recyclable. Our Products are perfect for the circular economy. Lead Recovered from our used batetries can be reprocess repeatedly without any loss on performance
Designed to perform in higher operating conditions with excellent life characteristics. In indoor applications such as data centres and general battery rooms, operators, when using these batteries, can increase room temperatures, and save on costly air-conditioning and other cooling costs.
