ZeMaRail

Hawker ZeMaRail VRLA, AGM and Gel are maintenance-free rolling stock batteries with gel instead of liquid electrolyte. The main effect of gel electrolyte in AGM-technology is the higher cycle performance and deep discharge resistance. An additional side effect of Gel electrolyte in AGM-technology is the more efficient heat management.

The hydrogen recombination is equal (up to 98%) than at a standard AGM type (gel with rigid separator has less). Those batteries are certificated by Swiss Federal Railways. The certification of includes: cycling, deep discharge, shock and fire protection requirements for the entire battery system including the tray.
