SRA, outstanding reliability for auxiliary backup in extreme temperatures

Outstanding reliability for auxiliary backup in regular and extreme temperatures

SRA is the latest in our new product development program to meet evolving customer critical function needs and keep operating costs down. SRA batteries are engineered to deliver outstanding performance and reliability to ensure the continuity of onboard auxiliary backup applications for passenger safety and fail-safe start-up systems – especially in the temperature extremes of Arctic cold or desert heat.

They are ideal for modern trains such as urban transit (metros, tramways, tram-trains, airport shuttles), regional transport (EMUs, DMUs) and intercity transport (high-speed trains, electric locomotives and passenger coaches).
