Nickel-cadmium batteries are ideally suited for rail transport in extreme conditions (for example very high and very low temperatures or strong vibrations), so that a safe journey can be guaranteed. The batteries are used both as emergency power batteries and as starter batteries for starting diesel engines and are tailored to customer needs. 
Robustness is a major advantage of NiCd batteries. Safe operation is guaranteed, even if conditions are not optimal for a short time. Thanks to the special technology, the calendar life of these batteries is particularly long; 15 years is not uncommon. Batteries from HOPPECKE can reach up to 3000 cycles. 
The rail | power FNC is frequently used as an on-board power supply battery in various types of rail vehicles, while the rail | power HNCS (a battery in sintered/PBE technology) is particularly used to cover high power requirements (for example emergency traction).
