Lead-acid battery for railway applications

In the rail lead-acid batteries in sealed design, the electrolyte is bound in a glass fibre fleece (Absorbent Glass Mat). The valve-regulated batteries are almost maintenance-free, as no water needs to be refilled. 
In addition, the high energy density leads to a space-saving design and therefore allows optimal use of the given installation space. They are leak-proof and can be used in various applications, including as an on-board power supply or starter battery, especially when minimal maintenance is required.
The stability of the batteries even under difficult environmental conditions is another advantage. The active mass is held firmly in the electrode even under high cycle loads, shock and vibration. The HOPPECKE ESS (Extended Stability Standard) means that unwanted overheating of the battery is excluded.
