FNC^®-A batteries are used on the railways and in automatic guided vehicle systems, in UPS installations and in standby systems (e.g. for lighting and monitoring). They possess all the benefits of FNC^® technology and are moreover characterized by enhanced charge acceptance and greater energy density, together with lower water consumption, extended maintenance intervals and longer service life.

Their compact, stable design improves the mechanical stability of all electrochemically active constituents, thereby distinctly enhancing the reliability of the overall system, and leading consequently to longer life even under the most extreme conditions of use.
