EPS Type batteries are made in AGM technology and are constructed by plates, separators, safety valves and a container. Since the electrolyte is held by a glass-mat separator and plates, the batteries can be used in any chosen position without the risk of leakage. EPS type batteries have a pressure relief valves that allows safe dispersal of any excess pressure inside the cell (VRLA). Due to advantages such as sealed construction, maintenance-free, low internal resistance, and long-term storage, EPS batteries are the base of the emergency power supplying.
