Description
The low-pressure valve keeps gases inside the cell, where up to 90 % of oxygen and hydrogen becomes water again, so electrolyte loss is minimal. At 20 °C the topping-up interval reaches 20 years and the service life is up to 25 years, so over the whole life the battery is serviced very rarely. At higher temperature evaporation increases and the interval shortens. The manufacturer's brochure states an operating range of −50…+60 °C, which makes it possible to install the battery in unheated cabinets at remote sites. FNC fiber-structure electrodes keep the resistance of the NiCd battery to deep discharges and mechanical loads. The design meets IEC/EN 60623.
How to choose
Between FNC-VR and the open FNC the choice is made by maintenance capability. If the site is visited rarely, the recombination version with a topping-up interval of up to 20 years is more convenient. The capacity and number of cells are determined by the required autonomy, from an hour to several days, and the UPS bus voltage. For rooms with a stable climate a gel or AGM series is enough, for example grid | power VR M with a service life of up to 15 years.

FAQ
How often should water be added to FNC-VR batteries?
The topping-up interval is up to 20 years at 20 °C. At higher temperature the electrolyte level should be checked more often.
What is the degree of gas recombination in FNC-VR?
Up to 90 %. The rest of the gas leaves through the low-pressure valve, so the room still needs ventilation.
In what temperature range does FNC-VR work?
According to the manufacturer's brochure from −50 to +60 °C. For projects at extreme temperatures, check the data for the specific cell type.
What is the service life of FNC-VR batteries?
Up to 25 years, and the batteries meet the IEC/EN 60623 standard.
What UPS autonomy can be obtained with FNC-VR?
The series is designed for autonomy from an hour to several days, and recombination of up to 90 % makes it suitable for remote sites.
