Nickel-Cadmium (Ni-Cd) : SPH – Low maintenance batteries
Saft SPH low maintenance Ni-Cd batteries are intended for rail applications that have frequent or infrequent discharges, such as starting and power back-up. The typical discharge range is from 1 second to 30 minutes.

Main applications

  • diesel engine starting
  • UPS

SPH batteries are an ideal alternative to VRLA (Valve Regulated Lead Acid) batteries, and provide:

  • low maintenance, thanks to gas recombination within cells to prevent water loss under normal conditions
  • capability to do the same job with a smaller capacity battery, by providing high power in a constrained voltage window
  • long lifetime of over 20 years
  • no temperature constraints
  • high resistance to electrical abuse
  • SPH batteries are designed for applications demanding a relatively high current over short periods and can provide very high currents of up to 20 times the battery’s nominal capacity.

Capacity range
11 Ah to 320 Ah
Example of battery name: SPH 320

Plate technology
Sintered / PBE: well-proven sintered positive electrode, a compact plastic bonded negative electrode (PBE).
