The grid | power FNC-VR is based on the proven Nickel Cadmium fibre structure technology. It therefore withstands the highest shock and vibration stresses and has a long service life and cycle life even under extreme temperature conditions. Due to the integrated low-pressure valve including a flame-resistant degassing port, the oxygen and hydrogen gases produced during charging are recombined with an efficiency of up to 90 %.

The grid | power FNC-VR is therefore extremely low-maintenance and water refilling can be extended to an interval of 20 years under optimal conditions. This significantly reduces the maintenance effort and the associated maintenance costs.

The battery is particularly well suited for stationary systems for uninterruptible power supply in the autonomy range between one hour and several days. Here, it can be operated safely even under extreme temperature influences with a long service life and good performance characteristics.
