Saft is at Innotrans 2012 to launch the latest addition to its portfolio of specialized railway batteries - the new SRA LT/HT series that deliver outstanding performance and reliability in auxiliary backup applications even when operating at extreme temperatures, both cold or hot. Visitors to Booth 15.1/226 can also see Saft’s high power engine starting solutions, including nickel-based capacitor and battery technologies, as well as Saft’s comprehensive range of batteries for backup applications from energy to high power.
Saft SRA LT/HT extreme temperature nickel-cadmium batteries ensure the continuity of auxiliary systems for passenger safety and fail-safe train start-up. They come in two versions: SRA LT that delivers a greater available capacity than standard Ni-Cd batteries at low temperatures (- 50°C to + 40°C), enabling a smaller battery to support the required load profile; SRA HT that offers superior charge efficiency at high temperatures (- 20°C to + 65°C) providing an increased capacity that ultimately results in a more compact battery solution.

The optimized electrical performance, extremely compact cells and very high energy density of the SRA LT/HT batteries are the ideal basis for battery systems that are lighter in weight and occupy less onboard space on a wide variety of modern trains such as urban transit (metros, tramways, tram-trains, airport shuttles), regional transport and intercity transport (high-speed trains, electric locomotives and passenger coaches).

The SRA design is fully compatible with Saft’s well established range of standardized railway battery systems while the robust and reliable Ni-Cd construction ensures a long and predictable service life.

Powering the perfect start for diesel engines
Reliable engine starting performance is a vital factor for the increasing number of train operators who demand multiple start capability to enable engines to be stopped during daily breaks in operation, saving fuel and reducing noise and gas emissions. Saft has responded to this challenge by developing advanced nickel-based capacitor and battery technologies that provide the high cranking power essential for consistent and reliable starting of large diesel engines on locomotives and DMUs.

Comprehensive range of auxiliary backup batteries
Saft is also showing its comprehensive range of batteries for auxiliary backup applications to suit all needs from energy to high power. Highlights of this range include the SRM+ that offers the ideal compact and cost effective solution when energy is the main requirement, together with the MRX for medium power applications, where its block format ensures fast and easy commissioning, installation and maintenance.
