Product Description
grid|power FNC
®
cells are connected to form battery systems and are deployed in standby
applications.
Here, they fulfil one or more of the following functions:
Buffering and supply of the low-voltage networks
Providing power in case of an emergency
To start a standby gen set/engine

cells are nickel-cadmium cells, which are produced with fiber structure
technology. It uses an extremely porous, three-dimensional synthetic fleece, metallized with
nickel.
The particular characteristics are:
The best volume/weight ratio by 90% volume filling of the fiber electrodes with active
material
High to very high values of current can flow during charging and discharging.
No carbonates are formed in the electrolyte.
The batteries have long service life and several charging cycles even under extreme
temperature conditions
It withstands the most extreme of stress caused by shocks and vibrations
Cell housings made optionally either of polyether sulphone, polyamide or polypropylene
A large variety of constructions ranging from high and extremely flat to low with a large
surface area
