Nickel-Cadmium (Ni-Cd) : SPL – Low maintenance batteries for railroad
Saft SPL Ni-Cd batteries are designed to provide standby power over relatively long discharge periods for rail infrastructure applications such as trackside power and signalling.

Main applications

  • rail trackside power
  • signalling

SPL batteries feature a block battery construction that offers peace of mind and a low overall cost thanks to these features:

  • complete reliability over a long predictable lifetime
  • excellent electrical performance and high resistance to electrical and mechanical abuse
  • operation in ambient temperatures from +40 °C to -30 °C, with extremes to -40 °C
  • minimal maintenance needs
  • capable of operating with renewable energy sources
  • lifetime of 20 years or more

Capacity range
80 Ah to 420 Ah
Example of battery name: SPL 420

Plate technology
The construction of the SPL cell is based upon Saft’s well proven pocket plate technology, but with special features to ensure low water usage by means of the gas recombination cycle
