FNC® batteries are produced using nickel-cadmium technology and find use in a wide variety of applications. 

These areas of application include in particular power stations, substations, UPS, solar,  telecommunications, and mains-independent power supply installations. FNC® batteries are also used in signalling and control equipment, and for diesel starting.

They have a useful life in service of up to 20 years, are very resistant to cycling (more than 2000 cycles as defined by DIN standards) and stand out for their extremely low internal resistance and high energy density. Long intervals between servicing and low life cycle costs are among the product benefits which they provide.

FNC® batteries are supplied with flashback-proof, hinged-lid vent plugs or AquaGen® recombination vent plugs.
