The wide range of low, medium and high capaity types makes accurate selection easy based on discharge time and end of discharge voltage. Robust construction and generous electrolyte reserve enable the battery to withstand wide temperature fluctuations in stationary cycling behavior over its +20 years life. Generally operating between temperatures of -20°C to +50°C, they can tolerate extremes of -50°C to +70°C for short periods.

With only periodic checks, the block battery will provide up to +20 years completely faithful service.

They are suitable for railroad signaling, control systems, photovoltaic, emergency lighting, telecommunications etc.
